Description

TECHNICAL FIELD

[0001] The present disclosure relates to the determination of the power output on a burner device by means of fuel parameters. In particular, it relates to a direct determination of the power output as a function of the air supply for a given air ratio λ. BACKGROUND

[0002] During the operation of a burner device, the ratio of fuel to air is to be adjusted. In this case, the following variants of the adjustment are known.

[0003] According to a first variant, the air actuator characteristic curve and the fuel actuator characteristic curve are determined by means of the power output during the adjustment process. The determination can be carried out, for example, from a small power output to a maximum power output or also vice versa. In this case, the air ratio λ is adjusted for each power output point. As a support, an air supply sensor can also be used. Current air supply sensors are based on rotational speed, mass flow, differential pressure, air volume flow, etc. The absolute power output is then determined by means of the measurement of the fuel supply at at least one point or at a plurality of points. By means of the calorific value H u of the fuel currently supplied, the burner power output is assigned to the respective characteristic point. The power output values of the other characteristic curve points are determined by interpolation, preferably by linear interpolation.

[0004] According to a second variant, the air actuator characteristic curve and the fuel actuator characteristic curve are determined in advance. The characteristic curves are mostly determined empirically in the laboratory. The burner power output is fixedly determined in advance by one of the two characteristic curves by means of a fixed function. Different characteristic curves and / or several groups of characteristic curves are fixedly determined in advance likewise for different fuels. Fundamentally, a new characteristic curve for a fuel with a calorific value H u0 of the fuel with a calorific value H u can be calculated by multiplication by a factor , wherein the result is produced. However, the air actuator characteristic curve must be corrected in appropriate cases, such that λ remains unchanged. In this case, the calorific value is the energy content per fuel quantity.

[0005] According to a third variant, the change in fuel composition is detected by means of a lambda sensor. This can for example be an O2 sensor in the exhaust gas, from which lambda is directly calculated. It is also possible for example to use an ionization electrode, whose signal is evaluated accordingly. In order to maintain the air ratio lambda constant, the air supply can remain unchanged, or the fuel supply can however be corrected until the lambda sensor measures the initial value of the air ratio lambda again. If the at least one air supply signal is readjusted in order to maintain the air ratio lambda constant, the power output also almost always changes with the fuel composition at this point in the characteristic curve. If the fuel supply signal is readjusted in order to maintain the air ratio lambda constant, the power output changes in accordance with the fuel. In order to adjust the power output, for the case of a power output correction, it is necessary to manually or automatically select or calculate a new characteristic curve of the air actuator.

[0006] The conventional gas types in burner installations are such gas types from the E-gas group (according to EN 437:2009-09) and gases from the B / P-gas group (according to EN 437:2009-09). Gases from the E-gas group include almost all gases from the second gas family in which methane is the main component (according to EN 437:2009-09). Gases from the B / P-gas group include all gases from the third gas family in which propane gas is the basis (according to EN 437:2009-09). Mixtures based on methane gas or propane gas ultimately represent mixtures from different gas sources, with which the burner installation can be supplied.

[0007] In general, for different gas types, characteristic curves are provided which are selected in the case of on-site commissioning according to the prevailing gas group. The adjustment is carried out for example by selecting one or more curves stored in the memory of the control unit. These characteristic curves represent the change in the amount of fuel supplied to the burner relative to the amount of air supplied. Instead of the amount of air supplied, the rotational speed of the blower in the air supply to the burner can be plotted. Furthermore, the position of the air valve flap and / or the control signal can be used as a measure of the air supply.

[0008] The characteristic curves can for example be stored in tabular form by means of linear interpolation or however also by means of polynomials as mathematical functions. The assignment of characteristic curves in this form is disclosed in European patent EP3299718B1 granted on 30 October 2019. The application EP3299718A1 for European patent EP3299718B1 was filed on 21 September 2016. European patent EP3299718B1 does not claim any priority.

[0009] If the air temperature, air pressure or air humidity changes little or is determined using measurement technology, the air quantity is suitable as a power output value. In the case of measurement of the air quantity using an air mass flow sensor, the influence of the air temperature and air pressure is taken into account. In the case of lower temperatures, the influence of the air humidity is in particular secondary.

[0011] EP2682679A2 relates to the start-up of operating points below and above a target air ratio. Subsequently, a signal of a mass flow sensor arranged in a pipe between an air line and a fuel gas line is plotted. From the signal, a correct or incorrect adjustment of the system is inferred.

[0015] It is an object of the present disclosure to provide as direct a power output adjustment as possible by means of the air supply. SUMMARY

[0016] It is an object of the present disclosure to provide as direct a power output adjustment as possible by means of the air supply. h , the fuel parameter directly determining an actual value of the power output of the burner device P ist . The air ratio λ is used in the determination. Specific parameters of the fuel can be calculated, for example, from values in the literature. The actual value of the power output of the burner device can be specified in kilowatts P ist . The actual value of the power output of the burner device can also be specified relative to a reference value P ist , the result being a relative actual value of the power output of the burner device P ist specified as a percentage of the reference value. In this case, a typical reference value is the maximum power output of the burner device P max .

[0017] The advantage is that only one air supply characteristic curve is required. The actual value of the power output of the burner device P ist can be assigned to the air supply quantity . In the case of a change in fuel and / or fuel composition, the fuel supply characteristic curve is corrected. In the case of a system in which λ is not determined, this correction is carried out manually. Otherwise, the correction can be carried out by means of a λ adjustment. The actual value of the power output of the burner device P ist is calculated from the known air supply quantity at the characteristic curve point by means of the known measured value of the air ratio λ and from the individual scalar fuel parameter . The minimum air requirement is a property of the fuel gas. The minimum air requirement describes the amount of air required for a certain amount of fuel in stoichiometric terms, in other words . The fuel parameter h is assigned to the fuel. The fuel parameter h can also be assigned to a fuel group of fuel compositions that are as close as possible to the fuel parameter h .

[0018] Conversely, it is also possible to determine the air supply quantity P soll for a specific target value of the power output of the burner device . The characteristic curve point is therefore likewise predetermined as a target, for example, air supply quantity . For a fuel-specific value h , the two parameters L min and H U must be related to the same amount. In other words,H U in megajoules per kilomole and L min in kilomoles per kilomole or H U in megajoules per cubic meter and L min are specified in cubic meters per cubic meter. These specifications assume identical environmental conditions, such as temperature and pressure. The actual value of the power output of the burner device can thus be adjusted directly by the power output regulator P ist . To this end, the target air supply is determined by means of λ and h is calculated from the target power output value . The actual air supply is subsequently adjusted to the target value by means of the measured variable . The fuel supply follows as a function of the corresponding adjustment of the λ value of the air supply .

[0019] A further related object of the present disclosure is to provide a method that makes it possible to determine the actual value of the power output of the burner device by means of the air supply P . ist

[0020] A further related object of the present disclosure is to adjust the air ratio λ by means of an O2 control loop using the determined correct fuel supply as the actual value and the target value derived from the target value characteristic curve determined by means of O2 regulation. In this case, rapid power output changes take place by means of the stored characteristic curve. In particular, the prevailing power output is also determined in the case of a change in fuel by means of the λ value determined by means of the measured O2 value and / or by means of the target value of λ.

[0021] A further related object of the present disclosure is to adjust the predetermined power output value by means of the power output control loop by means of the currently determined power output.

[0022] A further object of the present disclosure is to adjust the maximum fuel supply by means of a predetermined power output lower limit in the case of a change in fuel, with the result that a power output upper limit is achieved for each fuel. Preferably, the power output upper limit of each fuel is not exceeded.

[0023] A further object of the present disclosure is to adjust the minimum fuel supply by means of a predetermined power output lower limit in the case of a change in fuel.​ The result is a lower limit of the power output for each fuel. Preferably, the power output is not lower than the lower limit of the power output for each fuel.

[0024] Furthermore, it is an object of the present application that, by means of the adjustment of the fuel actuator, the individual scalar fuel parameters can be estimated and / or determined using lambda regulation h .

[0025] Furthermore, it is an object of the present disclosure that, by means of the calculated power output value, the energy turnover and / or the power output can be determined even in the case of a change in fuel.

[0026] It is a further object of the present disclosure that, by means of the calculated power output value and / or by means of the calculated energy value, the cost of the fuel can be determined even in the case of a change in fuel.

[0027] Furthermore, it is an object of the present disclosure to provide a burner device with a regulation and / or control and / or monitoring facility which has instructions for carrying out the method disclosed herein in a memory.

[0028] It is a further object of the present disclosure to provide a method and / or a device for determining the power output of a burner, the method being used in a burner device, such as, for example, an industrial combustion device and / or a heating system and / or an internal combustion engine, for example of a motor vehicle.

[0038] Figure 1 A burner device 1, such as for example a wall-mounted gas burner and / or an oil burner, is illustrated. During operation, a hot generator burns in a combustion chamber 2 of the burner device 1. The hot generator exchanges thermal energy of a hot fuel and / or a fuel gas into another fluid, such as for example water. The warm water is for example used for operating a hot water heating system and / or for heating drinking water. According to another embodiment, the thermal energy of the hot fuel gas can be used for heating products in an industrial process, for example. According to another embodiment, the hot generator is part of a system with a power output thermal coupling, for example a motor of such a system. According to another embodiment, the hot generator is a gas turbine. Furthermore, the hot generator can be used for heating water in a system in order to extract lithium and / or lithium carbonate. The exhaust gas is discharged from the combustion chamber 2, for example through a chimney.

[0039] The supply air 4 for the combustion process is supplied by a (motorized) operated air blower 3 of the burner device 1. Through a signal line 15, an adjusting and / or control and / or monitoring facility 13 specifies to the air blower 3 the air supply quantity it is to deliver. The air blower rotational speed is thus a measure of the delivered air quantity.

[0040] According to one embodiment, the air blower rotational speed of the adjusting and / or control and / or monitoring facility 13 is reported back by the air blower 3. If the air quantity is adjusted through an air valve flap 4 and / or a valve, the measured value of the valve flap position and / or the valve position and / or a signal from a mass flow sensor 12 and / or a volume flow sensor can be used as a measure of the air quantity. Said sensors are advantageously arranged in a pipe 5 for the air supply quantity . In an advantageous manner, said sensors provide a signal which is converted into a flow measurement value by means of a suitable signal processing facility. The signal processing facility ideally comprises at least one analog-digital converter. According to one embodiment, the signal processing unit, in particular one or more analog-digital converters, is integrated in the adjusting and / or control and / or monitoring facility 13.

[0041] The measurement value of a pressure sensor and / or a mass flow sensor 12 in the side pipe can also be used as a measure of the air supply quantity A combustion installation with a supply conduit and a side conduit is disclosed, for example, in European patent EP 3301364 B1. European patent EP 3301364 B1 was filed on July 7, 2017 and granted on August 7, 2019. Said patent claims a combustion installation with a supply conduit and a side conduit, wherein a mass flow sensor projects into the supply conduit.

[0042] The sensor 12 determines a signal corresponding to a pressure value, which depends on the air supply amount and / or the gas flow in the side conduit (particle flow and / or mass flow). In an advantageous manner, the sensor 12 provides a signal, which is converted into a measurement result value by means of a suitable signal processing installation. According to a further advantageous embodiment, the signals of a plurality of sensors are converted into a common measurement result value. The suitable signal processing installation ideally comprises at least one analog-digital converter. According to one embodiment, the signal processing installation, in particular the analog-digital converter(s), is integrated in the regulation and / or control and / or monitoring installation 13.

[0043] According to one embodiment, the gas flow is a value for the prevailing air through-flow rate. The air through-flow rate can be measured and / or specified in cubic meters air / hour. The air supply amount can be measured and / or specified in cubic meters air / hour.

[0044] The mass flow sensor 12 makes it possible to carry out measurements at high flow rates, in particular in connection with the burner installation during operation. Typical values for such flow rates are in the range between 0.1 meters / second and 5 meters / second, 10 meters / second, 15 meters / second, 20 meters / second or even 100 meters / second. Mass flow sensors suitable for the present disclosure are, for example, OMRON® D6F-W or SENSORTECHNICS® WBA type sensors. The available range of these sensors typically starts at a rate of between 0.01 meters / second and 0.1 meters / second and ends at a rate of, for example, 5 meters / second, 10 meters / second, 15 meters / second, 20 meters / second or even 100 meters / second. In other words, a lower limit such as 0.1 meters / second can be combined with an upper limit such as 5 meters / second, 10 meters / second, 15 meters / second, 20 meters / second or even 100 meters / second.

[0045] The fuel supply amount is adjusted and / or regulated by means of the regulation and / or control and / or monitoring installation 13 by means of a fuel actuator and / or a (motor) adjustable valve. Figure 1 The fuel in the embodiment illustrated in the middle is fuel gas. The burner device 1 can then be connected to different fuel gas sources, for example to a source with a high methane content and / or to a source with a high propane content. InFigure 1 In this case, the amount of fuel gas is adjusted by the (motor) adjustable fuel valve 9 by means of the regulating and / or control and / or monitoring facility 13. In this case, the control value 19 is, for example in the case of a pulse width modulated signal of the gas valve, the measurement of the amount of fuel gas. It is also the value 19 of the fuel supply amount According to a special embodiment, the fuel valve 9 is adjusted by means of a stepper motor. In this case, the step position of the stepper motor is the measurement of the amount of fuel gas. The fuel valve 9 can also be integrated in a unit with at least one or two safety shut-off valves 7 or 8. Furthermore, the fuel valve 9 can be a valve which is adjusted internally by means of a through-flow sensor, including a target value 19 and adjusting the actual value of the through-flow sensor to the target value 19. In this case, the through-flow sensor can be implemented as a volume flow sensor, for example as a turbine wheel flow meter, a bellows flow meter and / or a differential pressure sensor. The through-flow sensor can also be implemented as a mass flow sensor, for example as a thermal mass flow sensor.

[0046] If a gas valve flap is used as actuator 9, the position of the valve flap can be used as the measurement of the amount of fuel gas. Alternatively, the measurement value from the signal of a mass flow sensor and / or volume flow sensor can also be used as the measurement of the amount of fuel gas. This sensor is advantageously arranged in the supply line for the fuel. This sensor generates a signal which is converted into a flow measurement value (measurement value of the particle flow and / or mass flow and / or volume flow) by means of a suitable signal processing facility. The suitable signal processing facility ideally includes at least one analog-digital converter. According to one embodiment, the signal processing facility, in particular the analog-digital converter(s), is integrated in the regulating, control and monitoring facility 13.

[0047] The person skilled in the art recognizes that the above-mentioned values can also be calculated from a combination of variables determined by sensors. Those values are then the measurement of the fuel supply amount (particle flow and / or mass flow and / or volume flow) of the fuel gas. Furthermore, the person skilled in the art recognizes that the fuel supply amount of the liquid fuel can be determined in a similar manner.

[0048] Figure 2 The burner device 1 is illustrated with an air ratio sensor 20 for determining the air ratio λ. The air ratio sensor 20 for determining the air ratio λ comprises, for example, an O2 sensor. In one embodiment, the air ratio sensor 20 for determining the air ratio λ is an O2 sensor. The air ratio sensor 20 for determining the air ratio λ can be arranged, for example, in the combustion chamber 2 and / or in the exhaust gas path.

[0049] An air ratio sensor 20 generates a signal 21 for determining the air ratio λ. The signal 21 is read in and appropriately evaluated by the conditioning and / or control and / or monitoring facility 13. With the aid of signal 21, adjustments can be made for each air supply... Adjust the predetermined air ratio λ. In this case, through fuel supply... The actuator 9 in the middle and / or supplied by air Actuators 3 and 4 in the middle will measure the air supply volume Adjust to a predetermined target value.

[0050] Figure 3 The illustration shows a combustor device 1 with an air ratio sensor 20 for determining the air ratio λ, which includes an ionization electrode. KANTHAL® (e.g., APM® or A-1®) is commonly used as the material for the ionization electrode. Electrodes implemented by Nikrothal® are also considered by those skilled in the art. The ionization electrode may, for example, be arranged in the combustion chamber 2.

[0051] fuel supply The measured result variable can be used as the air supply quantity through the blower speed. Or the air supply through the position of the air valve. The direct characteristic curves are provided. The air valve position can be specified, for example, as an actuation angle. Combinations of speed and actuation angle are also possible. Figure 4 The diagram illustrates this direct characteristic curve.

[0052] Ideally, an air mass flow sensor can be used to determine the air supply. The corresponding characteristic curve is shown in... Figure 5 The air mass flow sensor can be installed, for example, directly in the air supply duct 11.

[0053] The air mass flow sensor can also be arranged in a bypass on the air supply duct 11 above the orifice. An arrangement with a bypass is known, for example, by European Patent EP3301362B1. Furthermore, the air mass flow sensor can be arranged in a bypass above the air valve disc that acts as the orifice.

[0054] Then, for example, the air supply is determined by a combination of the air mass flow rate signal and the air valve position, or by the air mass flow rate signal and the blower speed, or by all three. In principle, the air supply can also be determined by means of a differential pressure sensor above the orifice or air valve, or by any combination of an air mass flow sensor, blower speed, and / or air valve position. .

[0055] In this case, the air supply sensor generates the air supply amount. different measurement results. Thus, the measurement results obtained from the rotational speed and the valve flap position depend on other environmental conditions, such as the air pressure, the air temperature and the exhaust gas path. In order to improve the measurement accuracy , measurement values of environmental conditions, such as the supply air temperature, the air humidity or the absolute air pressure, can also be included in the determination. If an air mass flow sensor or a differential pressure sensor is used, the air supply quantity can be determined even without being influenced by environmental conditions. P ist . Depending on the measurement variable, the influence of environmental conditions, such as also the accuracy of the measurement, is reflected in the actual value of the power output of the burner device 1. In this case, the air supply quantity P and / or the actual value of the power output of the burner device 1 can be calculated in absolute or relative terms with respect to a maximum value and / or another value of the characteristic curve.

[0056] ist . Corresponding considerations apply to the measurement of the fuel supply quantity . The measurement variable of the fuel supply quantity can be a direct characteristic curve of the fuel supply quantity Figure 6 by means of the fuel valve position. The fuel valve position can be specified, for example, as an actuation angle.

[0057] Ideally, the air supply characteristic curve can be preset in the factory on the burner device 1 using, for example, an air mass flow sensor or a rotational speed sensor. Alternatively, the characteristic curve of the individual burner device 1 can also be calculated by means of a fuel meter and / or a fuel gas meter for determining with known fuel and an air ratio sensor 20 for determining the air ratio λ. The calculation is carried out using the relationship between the air supply quantity , the air ratio λ, the known minimum air requirement and the known fuel supply quantity , which is represented by

[0058] If the air supply quantity as illustrated above is adjusted in the factory or on the burner device 1 on site, the power output P ist of each fuel can be determined after the air ratio λ has been adjusted. For this purpose, known parameters are used. Using only one air supply characteristic curve, it is possible to limit the burner with known parameters for each fuel to a maximum power output to a minimum power output between 0.5 and 1.5. In this case, the air supply amount is limited and / or is limited according to . In the case of a change in the fuel or air ratio λ, the actual value of the power output of the burner device 1 can be recalculated and / or adjusted and / or limited directly at any point P ist .

[0059] For manual adjustment of the power output of the fuel, the minimum air requirement L min , the fuel parameters and the target value of the air ratio λ must be known. Initially, the fuel supply amount is calculated and adjusted by . The fuel supply amount cannot usually be entered directly. The fuel supply amount Figure 6 is then known only by the actuation angle of the fuel flap or fuel valve 6 according to the reference gas with the minimum air requirement L min0 . The fuel supply amount is then known only by the actuation angle of the fuel flap or fuel valve 6 according to the reference gas with the minimum air requirement min . The new fuel supply amount is then calculated as for another fuel with the same air ratio λ and the same air supply amount L ist in the case of a change in the air ratio λ with respect to the reference gas adjustment λ0, then is calculated. In the case of a change to a new fuel, the adjustment fuel actuator 9 changes the fuel supply amount 6 assigned to each air supply point by a factor and / or to the extent of a factor in the case of the same λ value. After the fuel supply amount 6 has been multiplied by the determined factor, the new control value and / or actuation angle 19 can be determined directly for the changed fuel composition by means of the known characteristic curve illustrated in . In this case, the characteristic curve can be provided, for example, in the form of a table, in which the intermediate values are interpolated in a linear manner. Furthermore, the characteristic curve can be provided as a mathematical formula and / or mathematical relationship. Figure 6 The power output can be calculated according to the above calculation for an unchanged air ratio λ in the case of the same air supply amount

[0060] and / or in the case of a changed air ratio λ as . In the case of an unchanged air ratio λ, the power output is if . In the case of a changed air ratio λ, the power output is ​​The parameters known from the literature can be used, for example and The fuel parameters known from the literature can be used, for example By means of this simple measure, the device is directly and in a simple manner adapted to the new fuel. There is no need to empirically determine a new characteristic curve. In this case, the corresponding power output P ist is also adapted to the new fuel. Advantageously, the correct air supply P soll and / or the correct fuel supply can be determined for a target value of the power output of the burner device 1

[0061] If the air ratio λ is determined by means of an O2 sensor or by means of an ionization electrode, the air ratio λ can be maintained constant by a control loop in the event of a change in the fuel composition. In the case of an O2 sensor, the air ratio λ is calculated directly from the result value of the sensor in accordance with the prior art. For example, the air ratio λ can be calculated from the oxygen content O2 by means of the relationship The fuel supply is then adjusted in such a way that a target value of λ is achieved by means of a control loop. The target value of λ can depend on the air supply In the case of the use of ionization signals and / or ionization flow signals for determining λ, the measured ionization flow is adjusted to a target value which depends on the air supply , wherein the fuel supply is changed.

[0062] In contrast to the reference fuel supply already set on the burner device 1, the new fuel supply is calculated over the entire modulation characteristic curve of the fuel by means of the power output In this case, the same air ratio λ is assumed. In this case, the actuator is adjusted accordingly, so that over the entire modulation range with regard to is replaced by the factor k . Thus, only the changed fuel needs to be adjusted at the power output point; the factor k is therefore known. By means of this factor k the changed fuel actuator position is known over the entire power output range, and thus the changed modulation characteristic curve is defined. The adjusted factor k identifies the unaltered λ according to the above calculation as .

[0063] If other air ratio target values are predetermined for another fuel (for example in the range of a fuel switch), the factor k is adjusted to . ​

[0064] If the fuel modulation characteristic curve has been adjusted for a reference gas with a known minimum air requirement L min0 , the minimum air requirement necessary for the currently prevailing fuel can be determined for the same lambda after adjustment of lambda by the determined factor k as . The minimum air requirement is determined for the changed as .

[0065] If the fuel composition is known, the new actual value of the power output of the burner device 1 P ist can also be calculated as as described above for each air supply point. The target value of the air supply amount P soll can be determined for each target value of the power output of the burner device 1 .

[0066] Figure 7 The minimum air requirement 22 is illustrated for different fuel gases, L min and the individual scalar fuel parameter 23, . As is apparent from Figure 7 , the fuel gases can be combined into groups. The groups are determined by the fact that for a prevailing air supply amount , the actual value of the power output of the burner device 1 P ist remains within predetermined limits also in the case of a change in the gas and in the case of an adjustment of the gas supply amount without changing the air ratio lambda. The individual scalar fuel parameter h then lies within the predetermined limits for each of these groups. The limits are determined by the admissible error of the actual value of the power output of the burner device 1 P ist .

[0067] It follows therefrom that in Figure 7 , the gases identified by the number 24 are gases of the second gas family (according to EN 437:2009-09), including special gases, but no Sardinian gas (= propane-air mixture). These gases have methane as a basis and are mixed with inert gases or smaller amounts of other fuel gases. If the gas is changed within this group and the air ratio lambda is kept constant by adjusting the fuel supply amount , the individual scalar fuel parameter of these gases identified by the number 24 is The actual value of the power output of the burner device 1 after adjusting the air ratio λ in the burner system P ist fluctuate in the range of less than 2%.

[0068] In Figure 7 the gases identified by the number 26 are gases of the third gas family (according to EN 437:2009-09); these gases have fuel parameters with an error of less than 8% with respect to the gases identified by the number 24. If this error is acceptable, no power output correction has to be implemented between the gas group 24 and the gas group 26. However, since it is usually known whether there is a liquid gas (= gas of the third family), a correction can be implemented manually, in which the individual scalar fuel parameters are input.

[0069] In Figure 7 the gases identified by the numbers 25, 27, 28 and 29 form further special gas groups (Sardinia gas, process gas). In each case it is known whether these gases are present and the respective value of the fuel parameter h can be input directly, so that a power output correction can be implemented. The error is for example less than 5.1%.

[0070] In Figure 7 the gas identified by the number 30 is pure hydrogen gas with .

[0071] As already mentioned above, in the case of a change of the gas group within the specified accuracy range, no power output correction has to be implemented. In the case of a change of the gas group to the gas group, it is known which gas group is present. The correction can be implemented manually by changing h .

[0072] Sometimes, different gases or gases from several gas groups come from different fuel supply lines and shut-off valves which close and open the respective fuel supply line. Then, the gas parameters can be changed by means of a switching of the fuel supply quantity . Thus, the power output or the burner modulation can be adjusted.

[0073] Known fuels are for example:

[0074] - natural gas from a supply network,

[0075] - liquid gas,

[0076] - gas on Sardinia,

[0077] - process gas with known composition (first gas family),

[0078] - liquid fuels, such as heating oil EL and the like,

[0079] - mixtures comprising hydrogen, and

[0080] - pure hydrogen.

[0081] Since each of the compositions is known, the individual scalar fuel parameters h are also known in each case.

[0082] If the special gas groups 15, 27, 28, 29 are excluded, the power output correction can also be further automated in this case, knowing when they are present. For this purpose, the factor k is determined by regulation. In order to determine the factor k , it is necessary to know the gas supply quantity of the reference gas (with L min0 ) as a linear equivalent of the position of at least one fuel actuator 9 or . This case is illustrated in Figure 6 . In this case, the factor k can be determined by regulation using an O2 sensor, an ionization sensor or any other similarly functioning sensor. Figure 8 for illustrating this method.

[0083] If the value 22 of L min is greater than the threshold value 31, it relates to a liquid gas with the value . Between the threshold value 31 and the threshold value 32, the gas can be interpreted as a methane gas with additives. This is essentially the case for gases from the second gas family from the supply network. The value is used here. Below the threshold value 32, the gas is interpreted as a hydrogen-methane gas mixture. Figure 8 The mixing ratio in L min changes there as a function of the composition, and thus of L min , along the characteristic curve identified by the number 30. Thus, the mixing ratio of the gas and / or the fuel can be used to specify a function of the fuel parameter h . Since the deviation with respect to methane with is relatively large in the case of hydrogen with the gas parameter , it is of particular interest to detect the H2 content in the methane by means of the lambda-regulated burner. Using the specified method, it is possible to automatically determine both the air ratio and the power output of the burner unit in the case of a predetermined air ratio lambda of hydrogen to, for example, methane, and to make the control unit available.

[0084] For known process gases and also for other gases (e.g. liquids, fuels), it is assumed that these do not occur in the general supply network. For these, a separate scalar fuel parameter h is assumed, if the respective fuel is fed in.

[0085] The current determined actual value of the power output of the burner installation 1 can be used P ist to directly operate the power output regulator in a closed control loop. The actual value of the power output of the burner installation 1 can be adjusted P ist to a predetermined target value of the power output of the burner installation 1 P soll .

[0086] The power output target value can be generated by a superordinate temperature control unit. It can also be predetermined as a target value directly by an operating unit and / or a unit for heating a product and / or in the case of a dominant residual fuel from a chemical process to the power output regulator.

[0087] As a result of , the maximum power output for the fuel installation 1 P max is implicitly adjusted to the maximum fuel supply , and the minimum power output for the fuel installation 1 P min is implicitly adjusted to the minimum fuel supply . Equivalently, and / or can be calculated upwards and limited and / or limited downwards to these calculated values for the respective fuel (directly). Thus, in any case, it is ensured that the burner installation does not operate outside the intended power output range.

[0088] The energy turnover can be calculated in a simple manner from the determined actual value of the power output of the burner installation 1 P ist , in which the actual value of the power output of the burner installation 1 P ist is integrated over time. Thus, the energy turnover can be calculated even in the case of a change in fuel.

[0089] If it is known when the fuel switches, the energy turnover of the individual fuel can be calculated. In the case of automatic recognition of the fuel parameter h , the switch can be detected by a change from h .

[0090] If the energy turnover is known, the energy costs can be determined directly, provided that the cost per energy unit is known. If the costs of the individual fuels differ, this switching can be detected as described above. Thus, the consumption costs of the individual fuels can be calculated.
