Abstract

The invention relates to a gas compressor applied to a gas turbine. The gas compressor comprises a gas compression turbine, a shell, a flame tube, a nozzle and an ignition device, wherein the nozzle is provided with a regulating valve for regulating the fuel spraying amount. A first air inlet valve and a second air inlet valve are arranged on the gas compression turbine, and an ultrasonic detection device emits ultrasonic waves to detect the carbon deposition thickness of the inner wall of the flame tube. A central control unit is connected with the regulating valve, the first air inlet valve,the second air inlet valve and the ultrasonic detection device and adjusts the regulating valve, the first air inlet valve and the second air inlet valve according to the detection result of the ultrasonic detection device. When the ultrasonic detection device detects that the carbon deposition thickness of the inner wall of the flame tube is not within the preset thickness range, the first air inlet valve and the second air inlet valve are adjusted to control the amount of air entering the flame tube, and the regulating valve is adjusted to control the fuel spraying amount, so that the air amount and the fuel spraying amount reach the optimal combustion ratio, and the combustion efficiency of a combustion chamber is improved.

Description

technical field [0001] The invention relates to the field of energy utilization, in particular to a compressor applied to 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 3 / 4-3 / 5) flows between the flame tube and the casing...
