One end of the flow meter communicates with the first connecting pipe, the first connecting pipe is provided with a shut-off valve, and the other end of the flow meter communicates with the second connecting pipe, the first flared pipe body, and the second flared pipe in sequence. Flanges for connecting pipe body, gas collecting guide cylinder and nozzle. The detection method includes step 1: cleaning; step 2: removing water; step 3: adjusting; step 4: recording data; step 5: calculating; step 6: detecting the other end of the nozzle gas path. The invention is a device and method specially used for air flow detection of nozzles of light-duty gas turbine combustors. The invention is used for detecting the gas flow rate of the combustion chamber nozzle of the gas turbine.

Description

technical field [0001] The invention specifically relates to an air flow detection method of a light-duty gas turbine combustor nozzle. Background technique [0002] The gas turbine combustor nozzle is a good combination of fuel and air, which accelerates the combustion speed of fuel in the combustor and improves the utilization rate of fuel. In the combustion chamber of a gas turbine, if the gas flow rate of the nozzle cannot meet the requirements, improper mixing of fuel and air and insufficient atomization will occur during the mixing process of air and fuel, which may cause combustion instability such as gas turbine flameout or flame pulsation. The combustion efficiency will not be very high. Therefore, the gas flow rate of the combustor nozzle directly affects the overall performance of the gas turbine. In view of the problems of unstable compressed air pressure and inaccurate readings of monitoring instruments in the gas flow detection of the combustor nozzle, compres...
