What is Combined Cycle Power Plant

What is Combined Cycle Power Plant

The gas-steam combined cycle is mainly composed of gas turbine (GT), waste heat recovery boiler (HRSG), steam turbine (ST) and its auxiliary facilities.
The gas turbine generator set, the waste heat boiler and the steam turbine generator set form a combined cycle system. The high-temperature flue gas generated by the gas combustion in the gas turbine combustion chamber drives the turbine blades to work and then enters the HRSG. The heat recovered by the HRSG heats the water into steam with different parameters. The steam enters the steam turbine to work. The gas turbine and the steam turbine drive the generator(s) to generate power.

Why we choose Combined Cycle Power Plant
