CCPP全拼是Combined Cycle Power Plant，中文叫燃气蒸汽联合循环发电机组，主要是先将高炉煤气经燃气压缩机加压，与压送至燃烧室的空气混合燃烧，生成高温、高压的气体，经燃气透平机膨胀做功，推动燃气透平带动压缩机和外部负荷高速旋转。从燃气透平中排出的废气引至余热锅炉，产生高温、高压蒸汽驱动汽轮机，与燃气透平一起带动发电机发电。
CCPP发电机组工艺主要系统有：煤气系统、烟气系统、空气系统及蒸汽系统。主要设备有：燃气轮机、煤气压缩机、空气压缩机、蒸汽轮机、发电机、余热锅炉、煤气电除尘器、煤气冷却器。
CCPP is a combined cycle power plant, which is called gas steam combined cycle generator set in Chinese. It is mainly to pressurize the blast furnace gas through the gas compressor and burn it together with the air sent to the combustion chamber to generate high-temperature and high-pressure gas. After the gas turbine expands and does work, the gas turbine drives the compressor and external load to rotate at high speed. The waste gas discharged from the gas turbine is led to the waste heat boiler to generate high-temperature and high-pressure steam to drive the steam turbine and drive the generator to generate electricity together with the gas turbine.
The main process systems of CCPP generator set include: gas system, flue gas system, air system and steam system. The main equipment includes: gas turbine, gas compressor, air compressor, steam turbine, generator, waste heat boiler, gas electrostatic precipitator and gas cooler.
