Description

[0001] Device for supplying energy to an object, use of an additional heater and object

[0002] The present invention relates to a device for supplying energy to an object, in particular a building, a hall, and / or a greenhouse, comprising at least one energy unit for generating thermal and electrical energy from a reaction gas mixture comprising oxygen and fuel gas. The at least one energy unit comprises at least one exhaust gas outlet for an exhaust gas stream, by means of which at least part of the thermal energy of the energy unit is released through the exhaust gas stream. Furthermore, the invention relates to the use of an additional heater and to an object.

[0003] It is known in the art that objects such as greenhouses are supplied with thermal and electrical energy using energy supply devices. Such devices can be called, for example, combined heat and power plants.

[0004] For example, DE 102015 104 071 A1 discloses a combined heat and power plant with an engine and a stationary exhaust system. The disadvantage is that the thermal energy and electrical energy generated by the combined heat and power plant are essentially constant. Changing the thermal energy generation alone while maintaining constant electrical energy is not possible or would result in a deterioration in efficiency.

[0005] A disadvantage of the energy supply devices known in the prior art is that the ratio of the resulting thermal energy to electrical energy is essentially constant. Thus, when thermal energy demand increases, for example, in winter, more electrical energy is generated, output, and / or converted. However, this is not always desirable.

[0006] The object of the present invention is to eliminate the disadvantages known from the prior art. In particular, the object is to create a power supply device in which the thermal energy can be controlled at least partially independently of the electrical energy. For example, an increased output of thermal energy should be ensured independently of the electrical energy.

[0007] The problem is solved by a device for supplying energy to an object, a use of an additional heater and an object having the features of the independent patent claims.

[0008] A device for supplying energy to an object is proposed. The device is preferably designed as an energy supply device, genset, and / or combined heat and power plant. The object is preferably designed as a building, hall, and / or greenhouse. The building can be, for example, a residential building, an office building, a warehouse, a cultural building, an assembly building, a sports hall, a swimming pool, a church building, a parking garage, a train station, an airport, and / or a hospital.

[0009] The device comprises at least one energy unit for generating thermal and electrical energy. For this purpose, for example, a fuel can be converted into thermal and electrical energy. The fuel can be a fuel gas, a liquid fuel, and / or a solid fuel. The fuel gas is preferably supplied to the energy unit together with oxygen as a reaction gas mixture. The reaction gas mixture comprises oxygen and fuel gas. The fuel gas is preferably a gaseous hydrocarbon and / or hydrogen. The device further comprises at least one exhaust gas discharge element for discharging an exhaust gas stream from the at least one energy unit. As described above, the reaction gas mixture, the fuel gas, the liquid fuel, and / or the solid fuel is converted into thermal and electrical energy. This conversion usually takes place with the aid of combustion, chemical reaction, and / or oxidation.The resulting gases are called exhaust gases. With the help of the exhaust gas discharge element, the exhaust gases can be discharged as an exhaust stream.

[0010] The exhaust gas stream often comprises at least a portion, preferably a large portion, of the thermal energy of the energy unit. Starting from the chemical energy content of the fuel, a portion is converted into electrical energy and a portion into thermal energy with the aid of the energy unit. Typically, 30%-40% of the chemical energy is converted into electrical energy. 50%-70% of the chemical energy is converted into thermal energy, which is at least partially released via the exhaust gas stream. The thermal energy of the exhaust gas stream can be used to heat the object, for example, with the aid of at least one heat exchanger and / or directly.

[0011] According to the invention, the device comprises at least one energy supply, wherein the at least one energy supply is in fluid connection, in particular in gas connection, with the at least one exhaust gas discharge element, so that additional thermal energy and / or chemical energy can be supplied to the exhaust gas stream.

[0012] An energy supply is understood to be an element with the aid of which energy can be supplied to the device, in particular in the region of the exhaust gas discharge element. As already described above, the energy can be supplied as thermal and / or chemical energy. Thermal energy is understood to be heat, for example in the form of a heat flow and / or warm air flow and / or warm exhaust gas flow. Chemical energy is understood to be a fuel, in particular a reaction gas mixture and / or a combustible gas, for example a gaseous hydrocarbon and / or hydrogen. The energy supply is preferably designed as an energy supply line with the aid of which the combustible gas and / or the reaction gas mixture and / or a heat flow can be supplied and / or passed to the exhaust gas discharge element.

[0013] This makes it possible to increase the thermal energy and / or chemical energy contained in the exhaust gas stream, in particular without affecting the conversion process within the energy unit.

[0014] It is advantageous if the at least one exhaust gas discharge element is designed as an exhaust gas duct. With the help of the exhaust gas duct, the exhaust gas flow can be discharged efficiently and / or with at least low resistance. Depending on the application, the exhaust gas duct can be thermally insulating or equipped with high thermal conductivity, so that low or high thermal energy is dissipated through the duct wall.

[0015] It is also advantageous if the at least one exhaust gas discharge element comprises at least one exhaust gas outlet for discharging the exhaust gas flow from the device.

[0016] It is also advantageous if the at least one energy unit comprises at least one opening, with the aid of which the exhaust gas flow is transported from the at least one energy unit into the at least one exhaust gas discharge element. The exhaust gas outlet and the opening preferably represent the two ends of the exhaust gas discharge element. It is also advantageous if the energy supply is designed as a heat supply for supplying the additional thermal energy. A heat supply is to be understood as a supply with the aid of which thermal energy, for example in the form of a heat flow and / or heated exhaust gas flow and / or heated air flow, can be supplied. The exhaust gas flow is thus directly heated with the aid of the heat supply.

[0017] It is also advantageous if the energy supply is designed as a fuel supply for supplying the chemical energy, in particular as a fuel gas and / or reaction gas mixture. The chemical energy introduced into the exhaust gas discharge element can be converted into thermal energy, for example, with the help of downstream means, for example with the help of an additional heater. The exhaust gas stream can thus be indirectly heated with the help of the fuel supply. The exhaust gas stream often contains a sufficient concentration of oxygen, so that only the fuel gas needs to be supplied with the help of the fuel supply. The fuel gas mixes with the exhaust gas stream, in particular in a mixing chamber and / or in the exhaust gas discharge element, such that a reaction gas mixture is formed.

[0018] It is also advantageous if the at least one energy supply comprises at least one supply valve and / or at least one supply line. The supply valve can be used to control and / or regulate the supply of thermal and / or chemical energy, particularly in the form of fuel and / or heat flow. The fuel and / or heat flow can be supplied to the supply valve via the supply line.

[0019] It is also advantageous if the at least one supply valve preferably extends into the at least one exhaust gas discharge element. It is also advantageous if the at least one energy supply, in particular the at least one supply valve, is arranged along a flow direction of the exhaust gas flow between the opening and the exhaust gas outlet. This allows the exhaust gas flow to be heated in a targeted manner.

[0020] It is also advantageous if the device comprises at least one auxiliary heater for generating the additional thermal energy. The auxiliary heater can, for example, convert the fuel gas and / or the reaction gas mixture into thermal energy. The fuel gas and / or the reaction gas mixture can be supplied to the auxiliary heater via the fuel supply in the region of the exhaust gas discharge element and / or directly.

[0021] Furthermore, it is advantageous if the at least one additional heater comprises at least one catalyst, in particular at least one hydrogen catalyst and / or at least one hydrocarbon catalyst.

[0022] With the aid of the at least one hydrogen catalyst, hydrogen can be burned flamelessly. A reaction gas mixture comprising hydrogen is fed to the hydrogen catalyst. The hydrogen content of the supplied reaction gas mixture or the hydrogen-oxygen mixture is preferably outside the explosive range, in particular below 4 vol. This prevents an explosion of the reaction gas mixture. With the aid of the at least one hydrocarbon catalyst, a gaseous hydrocarbon can be burned flamelessly.

[0023] The catalyst is preferably designed as a flow-through partition. Furthermore, it is advantageous if the catalyst is arranged in the at least one additional heater and / or in the exhaust gas discharge element such that the reaction gas mixture, the fuel, and / or the exhaust gas flow at least partially flows through it. If the exhaust gas flow, the fuel gas, and / or the reaction gas mixture flow through the catalyst, flameless combustion of the reaction gas mixture can be initiated, for example, with the aid of the thermal energy already contained in the exhaust gas flow.

[0024] Advantages are achieved if the catalyst is permeable, in particular as a grid, hydrophilic, and / or made of titanium. In this case, the catalyst is advantageously designed as a permeable grid. Additionally or alternatively, the catalyst comprises a base body with tubular and / or honeycomb-shaped reaction channels, wherein the base body is preferably made of monolith and / or ceramic, in particular cordierite and / or AlMg silicate.

[0025] It is also advantageous if the device comprises at least one heat exchanger. With the help of the heat exchanger, the thermal energy of the exhaust gas stream can be transferred to a heating fluid. The heating fluid can be, for example, heating water, domestic water, and / or supply air from an air heating device in the building. Since the exhaust stream often contains toxic substances and / or the oxygen content is reduced, this allows the building to be heated with the highest possible air quality.

[0026] It is also advantageous if the at least one energy supply and / or the at least one additional heater is arranged between the at least one opening of the energy unit and the at least one heat exchanger. This allows the thermal and / or chemical energy to be supplied to the exhaust gas stream before the heat exchanger extracts and / or converts the thermal energy to heat the object. It is also advantageous if the device comprises at least two heat exchangers. This makes it possible for the thermal energy contained in the exhaust gas stream to be transferred as completely as possible to the heating fluid and / or for as little thermal energy as possible to leave the device via the exhaust gas outlet.

[0027] It is also advantageous if the at least one energy supply and / or the at least one additional heater is arranged between the at least one opening of the energy unit and a first heat exchanger.

[0028] It is also advantageous if the at least one energy supply and / or the at least one additional heater is arranged between the first heat exchanger and a second heat exchanger. Additionally or alternatively, it is advantageous if the first heat exchanger and the second heat exchanger follow the at least one energy supply and / or the at least one additional heater along the flow direction of the exhaust gas flow. The second heat exchanger is preferably designed as a condensation heat exchanger. With the aid of the at least two heat exchangers that follow the at least one energy supply and / or the at least one additional heater, it is possible for the thermal energy contained in the exhaust gas flow to be transferred as completely as possible to the heating fluid and / or for as little thermal energy as possible to leave the device via the exhaust gas outlet.

[0029] It is also advantageous if the device comprises a cooling water heat exchanger. The cooling water heat exchanger can be in direct fluid communication with the cooling water of the energy unit, in particular the internal combustion engine and / or the gas turbine. Thus, the energy unit can be cooled with the aid of the cooling water heat exchanger, thereby providing thermal energy for the object. Preferably, the first heat exchanger, the second heat exchanger, and / or the cooling water heat exchanger are in fluid communication with one another.

[0030] It is advantageous if the cooling water heat exchanger is arranged within a cooling circuit of the at least one energy unit and / or is fluidly connected to the cooling circuit.

[0031] It is also advantageous if the at least one additional heater and / or the at least one catalyst is arranged within the exhaust gas discharge element, which is designed in particular as an exhaust duct. This allows the exhaust gas flow to be heated directly.

[0032] It is also advantageous if the at least one additional heater and / or catalyst, particularly arranged within the exhaust gas discharge element, follows the at least one energy supply designed as a fuel supply along the flow direction of the exhaust gas flow. The supplied fuel and / or the reaction gas mixture can thus be guided to the additional heater and / or catalyst along the flow direction with the aid of the exhaust gas flow.

[0033] Furthermore, it is advantageous if the exhaust gas discharge element, preferably in the region of the at least one energy supply, in particular designed as a fuel supply, comprises at least one mixing section, with the aid of which the fuel and / or the reaction gas mixture is mixed with the exhaust gas stream. If only the fuel gas is supplied by means of the fuel supply, the oxygen contained in the exhaust gas stream can be mixed with the fuel gas with the aid of the mixing section, so that the reaction gas is subsequently formed. The mixing section can be designed as a mixing chamber whose cross-section is similar to, identical to, or different from the cross-section of the exhaust gas discharge element.It is also advantageous if the at least one additional heater and / or the at least one catalyst is adjacent to the supply line of the at least one energy supply, designed in particular as a heat supply, and / or is arranged within the supply line of the at least one energy supply, designed in particular as a heat supply, so that the additional thermal energy generated by the additional heater and / or catalyst can be supplied to the at least one heat exchanger. Such an arrangement of the at least one additional heater and / or catalyst can be very easily retrofitted to existing devices. Furthermore, this arrangement can be more maintenance-friendly, since the additional heater and / or catalyst can be easily replaced.

[0034] Furthermore, it is advantageous if the device, in particular the exhaust gas discharge element, comprises at least one exhaust gas catalyst for purifying the exhaust gas flow. This ensures that the lowest possible levels of toxic and / or harmful substances and / or exhaust gases escape through the exhaust outlet. This is particularly advantageous for environmental protection.

[0035] It is also advantageous if the exhaust catalytic converter follows the energy supply and / or auxiliary heater along the flow direction. This allows for the post-treatment of potentially toxic and / or harmful substances and / or exhaust gases produced by the energy supply and / or auxiliary heater. This can further reduce pollutant emissions.

[0036] It is also advantageous if the energy unit is designed as a combined heat and power unit. It is also advantageous if the energy unit comprises at least one internal combustion engine, a gas turbine, and / or a fuel cell. The energy unit comprises a fuel inlet for supplying the fuel. The fuel inlet for the energy unit and the fuel supply for the auxiliary heater can be supplied by a common fuel supply. For example, it is advantageous if the energy unit and the auxiliary heater use the same fuel, in particular hydrogen.

[0037] It is also advantageous if the energy unit includes a generator for converting kinetic energy into electrical energy.

[0038] Furthermore, a use of an additional heater for supporting a device for supplying energy to an object, in particular a building, a hall and / or a greenhouse, is proposed.

[0039] According to the invention, the additional heater is arranged within an exhaust gas discharge element of the device and / or the additional heater is in fluid communication with the exhaust gas discharge element of the device by means of at least one energy supply designed as a heat supply, so that additional thermal energy generated by the additional heater can be supplied to the exhaust gas flow.

[0040] The device is preferably designed according to the preceding description, wherein the aforementioned features may be present individually or in any combination. The auxiliary heater preferably comprises at least one feature of the preceding description relating to the auxiliary heater, wherein the aforementioned features may be present individually or in any combination.

[0041] Furthermore, a system comprising at least one object, in particular a building, a hall, and / or a greenhouse, and at least one device for supplying energy to the object is proposed. The device is designed according to the invention as described above, wherein the aforementioned features may be present individually or in any combination.

[0042] Further advantages of the invention are described in the following exemplary embodiments. It shows:

[0043] Figure 1 is a schematic representation of a system with an object and a device for supplying energy to the object according to an embodiment, and

[0044] Figure 2 is a schematic representation of a system with an object and a device for supplying energy to the object according to an alternative embodiment.

[0045] Figure 1 shows a schematic representation of a system 22 with an object 21 and a device 1 for supplying energy to the object 21 according to an exemplary embodiment. The object 21 can be, for example, a building, a hall, and / or a greenhouse. The device 1 comprises an energy unit 2 designed to generate thermal and electrical energy. In the exemplary embodiment shown, this energy is generated, for example, via an internal combustion engine that is part of the energy unit 2. As an alternative to the internal combustion engine, the energy unit can comprise, for example, a gas turbine and / or a fuel cell.

[0046] Figure 1 shows an exhaust gas discharge element 3, which discharges the exhaust gas flow from the energy unit 2. The exhaust gas discharge element 3 is designed as an exhaust gas duct. Furthermore, the exhaust gas discharge element 3 comprises an exhaust gas outlet 6, through which the exhaust gas flow is discharged from the device 1. An opening 7 in the energy unit 2 enables the exhaust gas flow to be transported into the exhaust gas discharge element 3. The exhaust gas flow is guided by the exhaust gas discharge element 3 along a flow direction 10 from the opening 7 to the exhaust gas outlet 6.

[0047] The device 1 comprises at least one energy supply 4, 5. In the exemplary embodiment of Figure 1, the energy supply 4, 5 is designed as a fuel supply 5. Additionally or alternatively, the energy supply 4, 5 can be designed as a heat supply 4, which is shown and explained in more detail in Figure 2.

[0048] In the embodiment shown, the device 1 further comprises a supply valve 8 and a supply line 9, which are part of the energy supply 4, 5 designed as a fuel supply 5 and are in fluid connection with the exhaust gas discharge element 3.

[0049] The supply valve 8 and / or the fuel supply 5 is arranged along the flow direction 10 of the exhaust gas flow between the opening 7 and the exhaust outlet 6. Within the device 1, in particular within the exhaust gas discharge element 3, an additional heater 11 is located, which is designed to generate additional thermal energy, for example, from additional fuel gases and / or reaction gas mixtures. This additional heater 11 comprises a catalyst 12, which can be specifically designed as a hydrogen catalyst or a hydrocarbon catalyst. With the aid of the catalyst 12, the fuel gas and / or the reaction gas mixture, which is introduced in particular through the fuel supply 5, can be flamelessly burned.

[0050] The energy unit 2 comprises a fuel inlet 20 for supplying the fuel. The fuel inlet 20 for the energy unit 2 and the fuel supply 5 for the auxiliary heater 11 can be supplied by a common fuel supply. For example, it is advantageous if the energy unit 2 and the auxiliary heater 11 use the same fuel, in particular hydrogen. This allows the catalyst 12 of the auxiliary heater 11, which is designed as a hydrogen catalyst, to be operated.

[0051] Furthermore, Figure 1 shows the integration of at least one heat exchanger 13, 14 within the device 1, wherein the energy supply 4, 5 designed as a fuel supply 5 and / or the additional heater 11 are arranged between the opening 7 of the energy unit 2 and the at least one heat exchanger 13, 14. Specifically, two heat exchangers 13, 14 are shown, wherein the additional heater 11 and the energy supply 4, 5 designed as a fuel supply 5 are positioned between the opening 7 and a first heat exchanger 13 of the two heat exchangers 13, 14. Additionally or alternatively, the additional heater 11 and / or the energy supply 4, 5 designed as a fuel supply 5 can be arranged between the first heat exchanger 13 and a second heat exchanger 14, which can be designed as a condensation heat exchanger.

[0052] The device 1 further comprises a cooling water heat exchanger 15. In the illustrated embodiment, the cooling water heat exchanger 15 is arranged within a cooling circuit 17 and / or fluidly connected to the cooling circuit 17. Both the auxiliary heater 11 and the catalyst 12 are arranged within the exhaust gas discharge element 3, which is designed as an exhaust duct. The auxiliary heater 11 and / or the catalyst 12 are arranged along the flow direction 10 of the exhaust gas flow downstream of the energy supply 4, 5, which is designed as a fuel supply 5.

[0053] In the area of ​​the energy supply 4, 5, designed as a fuel supply 5, there is a mixing section 19 in the exhaust gas discharge element 3, which is responsible for mixing the fuel or reaction gas mixture with the exhaust gas flow. The auxiliary heater 11 and the catalyst 12 are adjacent to the supply line 9 of the energy supply 4, 5, designed as a fuel supply 5, and are configured so that the additional thermal energy generated by them can be passed on to the heat exchangers 13, 14.

[0054] Figure 1 also includes an optional exhaust gas catalyst 16, which serves to purify the exhaust gas flow and follows the auxiliary heater 11 and the energy supply 4, 5 in the flow direction 10. The energy unit 2 is designed as a combined heat and power unit and includes, among other things, a generator 18, which is responsible for converting kinetic energy into electrical energy. The generator 18 can provide the electrical energy for the object 21.

[0055] Figure 1 further shows the use of an additional heater 11 to support the device 1 in its function of supplying energy to an object 21. The additional heater 11 is positioned within the exhaust gas discharge element 3 such that the additional thermal energy it generates can be efficiently introduced into the exhaust gas stream. This allows additional thermal energy to be introduced into the device 1 without the energy unit 2 also having to increase the electrical energy and / or reduce the efficiency of the device 1. With the aid of the at least one heat exchanger 13, 14 and / or the cooling water heat exchanger 15, the object 21 can be supplied with thermal energy. Additionally or alternatively, it is conceivable that the thermal energy in the exhaust gas stream is used elsewhere for the object 21 and / or serves directly to heat the object 21.It is also conceivable that only one of the heat exchangers 14, 15 is arranged within the exhaust gas discharge element 3.

[0056] Finally, Figure 1 shows a system 22 that enables optimized thermal and electrical energy generation and utilization, with particular emphasis on the efficient use of waste heat and the minimization of energy losses. The illustrated device 1 is capable, for example, of providing both thermal and electrical energy for an object 21 and, moreover, ensures improved exhaust gas treatment through the use of the exhaust gas catalyst 16. However, it is also conceivable that the auxiliary heater 11 and / or the catalyst 12 provide improved exhaust gas treatment.

[0057] In the following description of the alternative embodiment shown in Figure 2, the same reference numerals are used for features that are identical and / or at least comparable in their design and / or mode of operation compared to the first embodiment shown in Figure 1. Unless explained in detail again, their design and / or mode of operation corresponds to the design and mode of operation of the features already described above.

[0058] Figure 2 shows a schematic representation of a system 22 with an object 21 and a device 1 for supplying energy to the object 21 according to an alternative embodiment. Here, too, the object 21 can be, for example, a building, a hall, and / or a greenhouse.

[0059] In contrast to the embodiment of Figure 1, the energy supply 4, 5 in the embodiment of Figure 2 is designed as a heat supply 4. The heat supply 4 is directly connected to the exhaust gas discharge element 3. The auxiliary heater 11 is not located inside, but outside the exhaust gas discharge element 3.

[0060] The energy supply 4, 5 designed as a heat supply 4 also comprises the supply valve 8 and the supply line 9. In contrast to the fuel supply 5 in Figure 1, the supply valve 8 does not control the supplied fuel, but rather a heat flow. The heat flow is generated with the help of the additional heater 11, in particular the catalyst 12 of the additional heater 11. With the help of the supply line 9, the heat flow can be supplied to the exhaust gas flow in the exhaust gas discharge element 3. Thus, in the embodiment in Figure 2, thermal energy is supplied to the exhaust gas flow with the help of the heat flow from the additional heater 11. In the embodiment in Figure 1, chemical energy is supplied to the exhaust gas flow with the help of the fuel supply 5.

[0061] The two exemplary embodiments in Figures 1 and 2 each show exemplary configurations. It is conceivable that an exemplary embodiment (not shown) comprises both the fuel supply 5 and the heat supply 4. It is also conceivable that the device 1 comprises more or fewer heat exchangers 13, 14. The heat exchangers 13, 14 can be designed as air / air heat exchangers and / or as air / water heat exchangers.
