Abstract

The invention relates to a gas turbine pneumatic control system based on three-dimensional axial flow. A central control processor is arranged to be connected with an ultrasonic detector, a temperature detector, a rotating speed detector and flow detection equipment and complete data exchange in real time; and meanwhile, the central control processor adjusts the opening and closing degree of an adjusting valve and an guide vane opening and closing angle in real time according to the carbon deposition thickness detected by the ultrasonic detector and the change of the axial flow in a gas compressor, so that the combustion effect in a combustion chamber of a gas turbine is improved; and meanwhile, high-temperature deformation of a gas turbine impeller caused by too high rotation speed of the gas turbine impeller or low efficiency caused by too slow rotation of the gas turbine impeller are avoided, so that the gas turbine is in a stable operation state, and the working efficiency and reliability of the gas turbine are improved.

Description

technical field

[0001] The field of the invention is specifically a gas turbine aerodynamic control system based on three-dimensional axial flow. Background technique

[0002] In the main process of air and gas in the gas turbine, only the gas turbine cycle composed of three major components: the compressor (Compressor), the combustor (Combustor) and the gas turbine (Turbine), is generally called a simple cycle, and the compressor sucks in air from the external atmosphere , and is compressed step by step by the axial flow compressor to increase the pressure, and the air temperature is also increased accordingly; the compressed air is sent to the combustion chamber and mixed with the injected fuel to generate high-temperature and high-pressure gas; and then enters the turbine Expansion works, pushing the turbine to drive the compressor and the external load rotor to rotate together at high speed, realizing the partial conversion of the chemical energy of the gas or liquid fue...
