Gas Turbine Generator and power plant

Gas Turbine Generator and power plant

Gas Turbine In the main process of air and gas, only the gas turbine cycle consisting of Compressor, Combustor and Turbine is called a simple cycle. Most gas turbines use a simple circulation scheme.
The compressor takes in air from the outside atmosphere and pressurizes it by the axial compressor to gradually pressurize it, 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. The gas then enters the turbine to expand and work, pushing the turbine to drive the compressor and the external load rotor to rotate at a high speed, thereby realizing the conversion of the chemical energy of the gas or liquid fuel into mechanical work and outputting electrical work. The exhaust gas discharged from the turbine is naturally radiated to the atmosphere. In this way, the gas turbine converts the chemical energy of the fuel into heat energy and converts some of the heat energy into mechanical energy. Usually in gas turbines, the compressor is driven by the expansion of the gas turbine, which is the load of the turbine. In a simple cycle, the mechanical work from the turbine is about 1/2 to 2/3 to drive the compressor, and the remaining 1/3 of the mechanical work is used to drive the generator. When the gas turbine is started, the external power is first required. Generally, the starter drives the compressor until the mechanical work generated by the gas turbine is greater than the mechanical work consumed by the compressor, and the external starter trips, and the gas turbine can work independently.
