Description

TECHNICAL FIELD

[0001] The present invention relates to an integrated performance verification test device and test method of a gas burner for testing various performances of a burner that burns mixed gas. BACKGROUND

[0002] Generally, combustible gas is converted into heat energy through a burner, and the combustible gas mainly uses LPG and LNG. Since the fire power of LNG and LPG is limited, there is a recent attempt to increase the fire power, and mixed gas using a mixture of various gases is used according to the utilization rate.

[0003] However, the fire power of the mixed gas varies according to the mixing ratio, and the burner and the flame are not easily observed to change according to the varying fire power, so it is difficult to grasp the standard of stability.

[0004] For example, a test device for testing mixed gas combustion is "Combustion Test Device" of Korean Registered Patent Gazette No. 10-1823102 (published on January 29, 2018).

[0005] The above-described conventional combustion test device forms a hollow shape with a burner that injects fuel and air, is connected to the downstream side of the burner, has a cavity that generates combustion gas by burning mixed gas in which the fuel and the above-described air are mixed, the cavity has a first cross section cut in a vertical direction, is located adjacent to the burner, and has a combustion chamber arranged according to the first and second cross sections of the combustion gas by a first cross section that generates combustion gas by burning mixed gas and a second cross section cut in a vertical direction. The flow direction of the combustion gas has a third cavity cut in a vertical direction, includes a third cavity placed on the downstream side of the second cavity to deliver the combustion gas to the outside of the cavity, the first cavity is wider than the second cavity, and the second cavity is narrower than the third cavity. The connection part connecting the second cavity with the first cavity and the third cavity is formed in a direction perpendicular to the flow direction of the combustion gas, and the combustion gas generated in the first cavity flows into the second cavity, the flow rate sharply increases according to the flow passage structure in which the second cavity is sharply narrowed, and the combustion test device provides a suffocation phenomenon by the combustion gas flowing through the second cavity.

[0006] The conventional combustion test device of such a structure can simulate a specific situation to perform a mixed gas combustion test.

[0007] However, the conventional combustion test device not only cannot perform a test of a burner caused by mixed combustion, but also cannot perform a comprehensive test of each component from a step of providing a burner to a step of measuring tail gas, so there is a problem that it is troublesome to perform a test while separately providing mixed gas.

[0068] The gas mixture supply unit (110) can supply the gas mixture to be burned to the burner (200).

[0069] The mixed gas can be commercial LNG or LPG mixed with the atmosphere, or it can be a mixture of natural gas (LNG) and hydrogen or other combustible gases.

[0070] The examples illustrate that the mixed gas is a mixture of natural gas and hydrogen.

[0071] The mixed gas supply unit (110) may include a gas tank in which natural gas and hydrogen can be mixed and filled according to a preset ratio, or supplied by changing the mixing ratio of natural gas and hydrogen.

[0077] Multiple gas metering units (120) can be selected to supply the mixed gas using burners (200), or the mixed gas can be supplied through any one of the burners (200).

[0078] Here, in order to measure the accurate efficiency of the burner (200), the information of the mixed gas supplied by the burner (200) can be measured by multiple gas supply measurement units (120), and the measured information is provided to the data acquisition server (190).

[0079] like Figure 1 and Figure 2 As shown, according to an embodiment of the present invention, the integrated performance verification test apparatus for a mixed gas burner may include a burner test section (130).

[0080] The burner testing section (130) can test the burner (200).

[0081] The burner (200) can burn the mixed gas supplied by the supply metering unit (120). The burner (200) can be a cast burner (200), a gas grill, a commercial large burner (200) (commercial gas stove, commercial soup pot, commercial sinker, commercial rice cooker, commercial fryer, commercial dishwasher) or a commercial hot water boiler.

[0082] The burner test section (130) may include a temperature measurement sensor (131) for measuring the flame temperature and the burner's own temperature. The temperature measurement sensor (131) may include a flame temperature sensor (131a) and a salt hole temperature sensor (131b). The flame temperature sensor (131a) can measure the flame temperature at multiple points, such as the flame center, the outer edge, and other different locations.

[0083] The flame temperature sensor (131a) can also understand the trend of temperature rise caused by backfire of the mixed gas by observing the temperature of the measured flame.

[0084] The salt hole temperature sensor (131b) can measure multiple parameters, such as the temperature of the gas injection section of the burner (200) and the temperature of the center of the burner (200). The salt hole temperature sensor (131b) can also measure the temperature of the salt hole metal section or the premixer on the burner (200) respectively.

[0085] The burner test section (130) may also be equipped with a backfire prevention device (133) to prevent backfire of the mixture supplied by the supply instrument section (120).

[0086] The temperatures measured by the flame temperature sensor (131a) and salt hole temperature sensor (131b) of the burner test section (130) can be provided as a data acquisition server (190).

[0087] The burner test section (130) may include a combustion camera.

[0088] A combustion camera can capture the flame of a burner (200) burning.

[0089] Combustion cameras can capture flames using visible light or infrared light, and can also capture the combustion state of a gas mixture through the flame.

[0090] The burner test section (130) may include an efficiency measuring device (135).

[0091] The efficiency measuring device (135) can measure the efficiency of the burner (200). The efficiency measuring instrument may include an efficiency measuring thermometer (135b) for measuring the heating temperature of the container (135a) heated by the burner (200) and filled with the heat medium and the heat medium filled inside the container (135a).

[0092] The efficiency measuring device (135) can measure the efficiency of the burner (200) by measuring the temperature of the heat medium filled in the container (135a) for a preset time. The temperature information and time of the heat medium measured in the efficiency measuring device (135) can be provided as a data acquisition server (190).

[0093] Here, the heat transfer medium used for charging in the container (135a) may be water.

[0094] According to an embodiment of the present invention, the integrated performance verification test apparatus for the mixed gas burner may include a safety device test unit (140).

[0095] The safety device testing section (140) can test the operation of the fire extinguishing safety device (210) installed on the burner (200). The fire extinguishing safety device (210) can be tested by measuring the operating status and operating sensitivity of the fire extinguishing safety device (210) based on the temperature of the burner (200), and by measuring the changing current value in the fire extinguishing safety device (210).

[0096] Among them, the fire extinguishing safety device (210) determines that the flame is extinguished when the combustion temperature of the burner (200) is lower than the preset combustion temperature, and cuts off the supply of mixed gas to the burner (200) to prevent mixed gas leakage.

[0097] The fire safety device (210) can cut off the supply of mixed gas to the burner (200) depending on the change in current value generated when temperature conditions change, such as a thermocouple or thermocouple.

[0098] The fire extinguishing safety device (210) can test the operational sensitivity of the burner (200) when the combustion temperature changes, or whether it is working, based on the mixing ratio or type of the mixed gas.

[0099] like Figure 1 As shown in the embodiment of the present invention, the integrated performance verification test device for the mixed gas burner may include an exhaust gas measurement unit (150).

[0100] The exhaust gas measuring unit (150) can measure the exhaust gas produced when the burner (200) is burning.

[0101] The exhaust gas measuring unit (150) can detect specific components such as NOx and CO, and measure the exhaust gas in the form of measuring the emission amount of the detected specific components.

[0102] The exhaust gas measuring unit (150) can be equipped with a cap (153) on the upper part of the burner (200). Exhaust gas is drawn in through the cap (153), and NOx and CO are detected in the drawn-in exhaust gas by a gas detector (151) to measure the exhaust gas in the form of measuring the emission of each component.

[0103] like Figure 1 As shown, according to an embodiment of the present invention, the integrated performance verification test apparatus for the mixed gas burner may include a test chamber (180).

[0104] The test chamber (180) can provide instrumentation (120), burner testing (130), safety device testing (140) and exhaust gas detection (150) in one test chamber, simulating the actual commercial environment.

[0105] The laboratory (180) comprehensively tests all processes from the supply of the gas mixture to combustion and the exhaust of the combustion gas in a room under simulated real environment conditions. By simulating the real environment, the measurement values ​​used in the actual environment can be obtained.

[0106] The test chamber (180) can be equipped with an environmental measurement sensor (181) to measure the state of the test chamber (180). The environmental measurement sensor (181) can measure the temperature, pressure and humidity inside the chamber, and conduct tests based on the measured temperature, pressure and humidity conditions.

[0107] Of course, the temperature, pressure and humidity information measured by the environmental measurement sensor (181) can be provided as a data acquisition server (190).

[0108] The laboratory (180) is equipped with a heater that can change the temperature, a humidifier that can change the humidity, and a positive or negative pressure device that can change the pressure. According to the actual environmental conditions of different regions, the burner (200) can be tested. The laboratory (180) can also test the combustibility of the burner (200) and the mixed gas under extreme environmental conditions.

[0109] like Figures 3 to 5 As shown, according to an embodiment of the present invention, the integrated performance verification test apparatus for the mixed gas burner may include an airtightness test unit (160).

[0110] When supplying a mixture to the burner (200) or the burner (200), the airtightness test unit (160) can be connected to a pipeline or the like to perform an airtightness test on the valve to control the supply of the mixture.

[0111] The airtightness test section (160) can perform airtightness tests on valves or burners (200) by generating negative pressure inside the cavity, supplying test gas to the valves or burners (200), and detecting test gas leaking into the cavity.

[0112] The airtightness testing unit (160) may include a test gas supply unit (161) and an airtightness testing machine (170).

[0113] The test gas supply unit (161) can measure the supply of test gas stored in the test gas tank through the meter (161a), and supply the measured test gas as the airtightness tester (170) through the test gas valve (161b).

[0114] The test gas supplied by the test gas supply department (161) has a molecular weight most similar to that of hydrogen. Helium (He), which is readily available on the market, can be used to conduct a gas tightness test based on hydrogen, which has the lowest molecular weight in the mixture of gases used for combustion.

[0115] The air tightness testing machine (170) obtains test gas supply through the test gas supply unit (161) and can perform air tightness tests on burners (200) or valves.

[0116] The airtightness testing machine (170) may include a mounting pad (171), a chamber (175), a pressure rupture (177), a linkage operating mechanism (176), and a negative pressure generator (174).

[0117] The stabilizing pad (171) can be formed in the form of a plate, and the stabilizing pad (171) can be used to mount a burner (200) or a valve.

[0118] The mounting pad (171) can be fitted with a supply nozzle (173) for supplying test gas. The supply nozzle (173) is inserted inside the supply port for supplying mixed gas to the valve or burner (200). The valve or burner (200) can be placed on the mounting pad (171).

[0119] An airtight gasket (171a) is installed on the part where the valve or burner (200) is located. The airtight gasket (171a) is used to seal the air inlet of the airtight valve or burner (200) and the fixing gasket (171). The valve or burner (200) can be placed on the upper part of the airtight gasket (171a).

[0120] The airtight pad (171a) can be formed from an elastic material with elastic force, so that it is pressed and adhered under the action of elastic force. The elastic material can be silicone, polyurethane, cyclohexanone, synthetic rubber, etc.

[0121] The shroud (175) is located above the stabilizer pad (171) and can cover the valve or burner (200) on the stabilizer pad (171), forming a cavity space between the stabilizer pad (171) and the shroud (175).

[0122] The cavity cover (175) can be formed into a box-shaped structure with an open bottom. The cavity cover (175) can be moved to the upper part of the placement pad (171) through the linkage mechanism (176) to open the cavity space, or the bottom can be tightly attached to the placement pad (171) to form an airtight cavity space.

[0123] A cover seal (175a) can be installed around the lower part of the hatch (175) to ensure an airtight seal between the hatch (175) and the retaining pad (171).

[0124] A gas sensor (178) can be mounted on the cavity hood (175) or placement pad (171) to detect test gas leaking into the cavity space.

[0125] Information about the gas detected in the gas sensor (178) can be provided as a data acquisition server (190).

[0126] Furthermore, a negative pressure generator (174) can be connected to the mounting pad (171) to discharge the internal air of the cavity space to the outside through a compressor (174a) or a pump, so that the internal cavity space of the cavity cover (175) is in a sealed state, thereby generating a near-vacuum negative pressure in the internal cavity space of the cavity cover (175).

[0127] The pressurized wave region (177) can pressurize the valve or burner (200) mounted on the fixed pad (171) onto the airtight pad (171a), while the valve or burner (200) is firmly supported on the fixed pad (171).

[0128] In order to prevent the pressurized wave area (177) from sealing the test gas vent from the valve or burner (200), the pressurized wave area (177) may form multiple vent holes (177a) that can vent the test gas leaking from the valve or burner (200).

[0129] The central portion of the pressurized wave region (177) protrudes upward in the form of a pipe, maximally shielding the valve or burner (200) from the pressurized portion of the pressurized wave region (177), thus preventing test gas leaking from the burner (200) or valve from being discharged into the cavity space.

[0130] The pressurized breakage zone (177) and the chamber cover (175) are arranged in sequence to tightly attach the chamber cover (175) to the placement pad (171). The pressurized breakage zone (177) can pressurize and break the valve or burner (200), or release the pressure of the valve or burner (200) through the pressurized breakage zone (177) and activate the chamber cover (175) on the placement pad (171).

[0131] The linkage operation mechanism (176) includes a cylinder in which the piston shaft (176a) moves under air or oil pressure. The cylinder is composed of an upper frame (172) on a mounting pad (171) that moves upward from a partition (172a) and the cylinder is mounted on the upper frame (172).

[0132] In addition, on the piston shaft (176a) where it appears, the cavity cover (175) located below the upper frame (172) and the pressurized vent (177) located inside the cavity cover (175) are combined. On the piston shaft (176a), when the piston shaft (176a) appears at a certain distance, the cavity cover (175) is pressurized and lifted, or it is tightly supported with the cup (176b) to form the upper and lower covers (175b) and the upper and lower covers (176b can be).

[0133] The upper brake beam (176b) refers to the upper brake beam (176b) placed on the bottom of the chamber cover (175) when the piston shaft (176a) moves upward to a certain height. The piston shaft (176a) can move the chamber cover (175) to the upper part of the stabilizer plate (171), thereby opening the cavity space.

[0134] If the piston shaft (176a) moves downward to a certain height, the chamber cover (175) can pressurize the stabilizer pad (171) to provide a fitting pressure.

[0135] At this time, between the lower brake beam (176c) and the cavity cover (175), when the piston shaft (176a) moves down, a cover spring (176d) that elastically supports the cavity cover (175) is installed on the lower brake beam (176c), so that the lower brake beam presses the cover spring (176d) in the direction where the cavity cover (175) is located, thereby improving the safety and airtightness of the installation on the mounting (171).

[0136] The end of the piston shaft (176a) is fitted with a pressure corrugation (177), which can pressurize and fix the valve or burner (200) in close contact with the airtight gasket (171a) if the piston shaft (176a) moves downward.

[0137] In this way, the pressure of the pressurized rupture (177) pressurizes the top of the fixed burner (200) or valve, and the supply pressure of the test gas separates the combined parts. This not only prevents the burner (200) or valve from hitting the inside of the cavity space and damaging the cavity cover (175), but also makes it easy to remove the burner (200) or valve from the fixing pad (171).

[0138] like Figure 1 As shown, according to an embodiment of the present invention, the integrated performance verification test apparatus for the mixed gas burner may include a data acquisition server (190).

[0139] The data acquisition server (190) can receive and store information provided by the examination department, instrument department, and measurement department, and output the stored information or output the examination results.

[0140] For example, the data acquisition server (190) can issue product performance records supplied by the mixed gas supply unit (110) based on the combustion rate and gas consumption measured by the burner test unit (130) and the efficiency measuring device (135), or evaluate the airtightness performance of the valve or burner (200) by the airtightness tester (170) and issue evaluation results records, or issue results information in various forms through the burner (200) based on the temperature measured by the burner test unit (130).

[0141] In addition, the data stored on the data collection server (190) can also be used as the basis for the future development of the burner (200).

[0142] The roles and effects of each component will be explained below together with the test method of the integrated performance verification test device for the mixed gas burner in the embodiments of the present invention.

[0143] According to an embodiment of the present invention, the test method of the integrated performance verification test device for the mixed gas burner is as follows: First, the mixed gas is supplied to the burner (200) through the mixed gas supply unit (110).

[0144] The mixed gas supply unit (110) can mix and supply different gases in a storage tank containing different gases at a preset ratio or the required ratio.

[0145] The mixed gas supply unit (110) is converted to a certain pressure by the regulator (115), which can be supplied as a burner (200).

[0146] Before the gas mixture supply unit (110) supplies the gas mixture to the burner (200), the supply unit (120) measures the amount of gas mixture supplied by the gas meter (121), and the measured information can be provided as a data acquisition server (190).

[0147] The gas meter (121) can be equipped with a pressure sensor and a temperature sensor to measure the supply pressure and temperature of the mixed gas.

[0148] If the supply metering unit (120) measures the amount of mixed gas supplied to the burner (200), it supplies mixed gas to the burner test unit (130), and the burner (200) installed in the burner test unit (130) burns the mixed gas to test the burner (200).

[0149] The burner test section (130) measures the temperature of the flame and the burner (200) itself using a flame temperature sensor (131a) and a salt hole temperature sensor (131b).

[0150] The flame temperature of the gas mixture is measured by a flame temperature sensor (131a), which measures the flame temperature at multiple locations on the flame.

[0151] Here, the flame is not only measured on the flame temperature sensor (131a), but the flame can also be photographed by the flame imaging camera to capture the combustion state of the mixed gas.

[0152] Then, the salt hole temperature sensor (131b) measures the temperature of the salt hole metal section or premixer. The salt hole temperature sensor (131b) measures the temperature of multiple salt hole metal sections or premixers at multiple locations and provides the temperature information of each measurement to the data acquisition server (190).

[0153] At the same time, the burner test unit (130) will measure the current value of the fire extinguishing safety device (210) on the safety device test unit (140) installed on the burner (200), and provide information on whether the fire extinguishing safety device (210) is working and its working sensitivity to the data acquisition server (190) based on the measured current value.

[0154] When the mixed fuel is burned in the burner (200), the combustion efficiency of the burner (200) is measured by the efficiency measuring device (135) of the burner (200). The efficiency measuring device (135) heats the heat medium in a container (135a) for a preset time when the heat medium is filled in the container (135a) and measures the efficiency of the burner (200) by measuring the temperature change.

[0155] Of course, the temperature, time and other information measured by the efficiency measuring device (135) will be provided as data acquisition server (190).

[0156] Then, when the burner (200) is tested in the burner test section (130), the exhaust gas generated by the mixed gas of the burner (200) is collected from the exhaust gas measurement section (150), and the content of specific components in the exhaust gas is measured by the gas detector (151).

[0157] The amount of specific components detected in the exhaust gas measured by the exhaust gas measuring unit (150) can be provided as a data acquisition server (190).

[0158] Furthermore, the burner test section (130) can be equipped with a backfire prevention device (133) to prevent the mixed gas supplied by the burner (200) from backfire. In the event of backfire, the combustion state of the burner (200) can also be photographed by a flame camera to observe the flame state caused by the backfire.

[0159] In addition, when testing the burner (200), the burner test section (130), supply measurement section (120), exhaust gas measurement section (150), and safety device measurement section form an environment in the test chamber (180) just like using the burner (200) in an actual environment. The test chamber (180) can be tested under the extreme conditions of the actual environment, such as temperature, humidity, pressure, etc., for heaters, humidifiers, positive pressure or negative pressure devices.

[0160] At this time, the laboratory (180) can maintain certain environmental conditions by measuring the temperature, humidity and pressure information by the environmental measurement sensor (181), and the information measured by the environmental measurement sensor (181) can be provided as a data acquisition server (190).

[0161] In addition, the airtightness test unit (160) can perform airtightness testing on valves or burners (200), and the information tested by the airtightness test unit (160) can be provided as a data collection server (190).

[0162] When conducting a gas tightness test on a valve or burner (200) in the gas tightness test section (160), in order to transport the valve or burner (200) to be tested into the cavity cover (175), the linkage mechanism (176) is activated to move the piston shaft (176a) upward.

[0163] When the piston shaft (176a) moves upward, the pressure wave area (177) located at the end of the piston shaft (176a) moves upward. On the upper brake beam formed by the piston shaft (176a), the lower end of the cavity cover (175) rests on the lower end of the cavity cover (175), and the cavity cover (175) also moves upward from the mounting plate (171) together, opening the cavity space.

[0164] When the cavity space is open, position the supply nozzle (173) of the test gas supply in the area so that it faces the supply port of the valve or burner (200), and then activate the linkage operation mechanism (176) to move the piston shaft (176a) downward.

[0165] When the piston shaft (176a) moves to the port, the chamber cover (175) is fixed to the stabilizing pad (171) by the load, the chamber space is sealed, and the pressurized rupture (177) continues downward to the piston shaft (176a) until the burner (200) or valve top is pressurized.

[0166] As the piston shaft (176a) descends, the lower brake beam (176c) formed on the piston shaft (176a) also descends, pressurizing the cover spring (176d) located between the chamber cover (175) and the lower brake beam (176c). The elastic force of the cover spring (176d) presses the chamber cover (175) tightly against the fixing pad (171) through the fixing pad (171), making it fit tightly. Gas is supplied inside the chamber cover (175) to prevent leakage through test (177). (200) or the top of the pressurizing valve, so that the air inlet of the burner (200) or valve is tightly pressed together through the airtight pad (171a).

[0167] If the airtight hood and burner (200) or valve are fixed by the linkage operation mechanism (176), air is released into and out of the chamber space through the negative pressure generator (174) port, so that the chamber space is in a vacuum state below atmospheric pressure.

[0168] If the cavity space is in a vacuum state, the test gas supply unit (161) provides test gas as a gas tightness tester (170). The test gas is supplied by the burner (200) or valve through the supply nozzle (173) at a preset pressure.

[0169] If the test gas is supplied within a preset time and the test gas cannot be detected by the gas sensor (178) inside the chamber (175), it can be determined that the burner (200) or valve is airtight; if the test gas is detected, it can be determined that the burner (200) or valve is not airtight.

[0170] The results or information of the airtightness test of the burner (200) or valve can be sent to the data collection device for storage and the test results can be issued.

[0171] After the airtightness test is completed, if the linkage mechanism (176) moves the piston shaft (176a) upward, the pressurized valve or burner (200) will be released from pressure to release its fixation. If the piston shaft (176a) moves upward, the upper brake beam (176b) will suspend the bottom of the chamber cover (175) from the bottom of the chamber cover (175), and the chamber cover (175) will be installed upward together, opening to the outside from the upper exhaust chamber cover (171), thereby allowing the air in the chamber cover to move upward from the test space. The airtightness test can be performed with the valve or burner (200) being removed.

[0172] Therefore, according to an embodiment of the present invention, the test method of the integrated performance verification test device for the mixed gas burner is to comprehensively collect and test information from the initial mixed gas supply to the supply as a burner (200) and the various components that generate exhaust gas during the combustion process. This method is not only easy to test and collect data, but also allows for the digitization of various information into large data. Through this large data, the safety standards of the burner (200) can be conveniently set, and a safe burner (200) can be developed.

[0173] Furthermore, by providing mixed gas in multiple proportions through the mixed gas supply section (110), the present invention not only facilitates testing of the burner (200) as the mixed gas mixing ratio changes, but also measures the combustion rate of the mixed gas, gas consumption, etc., thus enabling product evaluation of the mixed gas.

[0174] In addition, the present invention can also install an efficiency measuring device (135) on the burner (200) to conveniently measure the efficiency of the burner (200).

[0175] Furthermore, the present invention can measure not only the temperature of the burner (200) itself, but also the temperature of the flame in the burner test section (130) through the salt hole temperature sensor (131b) and the flame temperature sensor (131a), observe the temperature changes caused by the mixed fuel, and also take pictures of the flame through the flame photography camera to understand a more accurate combustion state.

[0176] Furthermore, the present invention can also conveniently measure the amount of exhaust gas produced during combustion using an exhaust gas measuring instrument (150).

[0177] Furthermore, the present invention can simulate the environment in which the burner (200) is actually used and test each configuration, thus providing accurate information on the use of the burner (200) in a real environment.

[0178] Furthermore, since the present invention is installed in a test chamber (180), the combustion state of the burner (200) under various environmental conditions or extreme combustion conditions can be easily monitored.

[0179] In addition, the present invention can not only conveniently test the airtightness of valves or burners (200) through the airtightness test section (160), but also form a negative pressure in the internal space of the chamber (175) to quickly determine the test gas leakage caused by poor airtightness.

[0180] Furthermore, the present invention also uses the linkage operation mechanism (176) in the airtightness test section (160) to link the chamber cover (175) and the pressurized rupture (177) to work together, which not only makes it convenient to install and remove the valve or burner (200) to be tested in the airtightness test section (160), but also allows for rapid testing.

[0181] The embodiments of the present invention have been described above, but the scope of the present invention is not limited thereto, and includes all changes and modifications in the technical field to which the present invention pertains that are easily altered by a person with ordinary knowledge and are considered to be of equal scope.
