Gas turbine (Gas Turbine) is gas continuously to flow as working medium impeller high speed rotation, by fuel
Energy conversion be useful work internal combustion type dynamic power machine, be a kind of rotary vane type Thermal Motor.
Gas turbine structure is most simple, and best embodies out small in size, light-weight, starting specific to gas turbine
Fastly, less with or without series of advantages such as cooling waters.Gas turbine is in working medium and the main flow of combustion gas, only compressor
(Compressor), the gas turbine cycle of this three big component composition of combustion chamber (Combustor) and turbine (Turbine), leads to
Referred to as simple cycle.Most of gas turbines are all made of simple cycle scheme.
Working medium is inhaled from the outside atmospheric environment in compressor, and is allowed to be pressurized by axial-flow compressor step by step compression, simultaneously
Temperature of Working also correspondinglys increase；Compression working medium is pressed to combustion chamber and the fuel of penetrating is mixed and burned the gas for generating high temperature and pressure
Body；Then expansion work in turbine is entered back into, pushes turbine that compressor and external load rotor is driven to rotate together at high speed, is realized
The chemical energy of gas or liquid fuel is partially converted into mechanical work, and exports electric work.The exhaust gas being discharged from turbine drains into greatly
Gas nature heat release.In this way, the chemical energy of fuel is just converted into thermal energy by gas turbine, and partial heat energy is transformed into mechanical energy.
