Abstract

The invention relates to a compressor applied to a gas turbine. The device comprises: a compressor turbine, a casing, a flame tube, a nozzle and an ignition device. A regulating valve is arranged on the nozzle to adjust the amount of fuel ejection; the compressor turbine is provided with a The first intake valve and the second intake valve, the ultrasonic detection device emits ultrasonic waves to detect the thickness of carbon deposits on the inner wall of the flame cylinder; the central control unit communicates with the regulating valve, the first intake valve, the second intake valve and the ultrasonic The detection device is connected, and the central control unit adjusts the regulating valve, the first intake valve and the second intake valve according to the detection results of the ultrasonic detection device; when the ultrasonic detection device detects that the carbon deposit thickness on the inner wall of the flame cylinder is not within the preset thickness range , then adjust the first intake valve and the second intake valve to control the air volume entering the flame cylinder and adjust the regulating valve to control the fuel injection volume, so that the air volume and the fuel injection volume can reach the best combustion ratio, so that Improve the combustion efficiency of the combustion chamber.

Description

technical field [0001] The invention relates to the field of energy utilization, in particular to a device for improving the combustion efficiency of a combustion chamber of a gas turbine. Background technique [0002] The main function of the combustor is to mix the high-pressure air from the compressor turbine with the fuel injected by the fuel nozzle and burn it through equal pressure, convert the chemical energy stored in the fuel into heat energy, form high-temperature gas and send it to the turbine to drive the turbine to do work . [0003] The combustion chamber is composed of shell, flame tube, nozzle, vortex, ignition device and so on. The high-pressure air from the diffuser section of the compressor is divided into two streams: one stream (accounting for about 1 / 4-2 / 5) enters the front of the flame tube, mixes with the fuel sprayed from the nozzle to form an oil-air mixture, and burns after being ignited by the ignition device . The other stream (accounting for ...
