Gas Power Station Boiler is the same name of Gas Power Plant Boiler. It is another type of gas steam boiler used to generate electricity. In May 2019, power plant boiler manufacturer Taishan Group won a project of changing coal into gas. The project consists of two sets 170 tons per hour natural gas power station boilers.

The gas power station boiler is single drum natural circulation chamber combustion vertical steam boiler. Burners are under the side walls of the furnace; the economizer has three stages, and air preheater has one stage. The air preheater is tube type, the frame is steel structure, and the tail is superimposed structure. The inside of drum adopts cyclone separator for primary separation of steam and water, and steel mesh and shutter for secondary separation. The temperature control of superheated steam adopts self-made condensate spraying desuperheating device. The furnace adopts membrane wall, and the water supply adopts centralized downcomer; platform and staircase are of grid structure.
