The working process of the gas turbine is that the compressor (ie, the compressor) continuously draws in air from the atmosphere and compresses it; the compressed air enters the combustion chamber, mixes with the injected fuel, burns, becomes high-temperature gas, and then flows into the gas turbine. The expansion work is carried out to push the turbine impeller to rotate together with the compressor impeller; the function of the heated high-temperature gas is significantly improved, so that the gas turbine drives the compressor while still having the remaining work as the output mechanical work of the gas turbine. When the gas turbine is started from a standstill, it needs to be rotated with the starter. After it is accelerated to be able to operate independently, the starter will be disengaged.
The working process of a gas turbine is the simplest, called a simple cycle; in addition, there are regenerative cycles and complex cycles. The working fluid of the gas turbine comes from the atmosphere, and finally to the atmosphere, which is an open cycle; in addition, there is a closed cycle in which the working fluid is closed and recycled. The combination of a gas turbine and other heat engines is called a compound cycle device.
The initial temperature of the gas and the compression ratio of the compressor are the two main factors affecting the efficiency of the gas turbine. Increasing the initial temperature of the gas and increasing the compression ratio accordingly can significantly increase the efficiency of the gas turbine. In the late 1970s, the compression ratio reached a maximum of 31; the initial gas temperature of industrial and marine gas turbines was up to 1200 °C, and that of aviation gas turbines exceeded 1350 °C.
