Types and Mechanism of Thermal Power GenerationOur Company / Thermal Power Stations

Thermal power generation is the process of obtaining thermal energy by burning fuels such as LNG etc., to convert into electric energy by using power- generating facilities.

Steam Power Generation

Steam power generation is a power generation method utilizing the expansion power of steam. Hot and high-pressure steam is generated from heat by burning heavy crude oil, LNG (liquefied natural gas), coal, etc. This steam is used to rotate the impeller in a turbine and activates a generator connected to the turbine to generate electricity. Steam power generation uses thermal energy with a relatively low temperature (600°C or lower).

Combined Cycle Power Generation

Combined cycle power generation is a power-generation method combining a gas turbine and a steam turbine.
High thermal efficiency can be achieved by combining two methods of power generation: gas turbine power generation from rotating a generator utilizing expansion power by generating combustion gas via burning fuels in the compressed air, and steam power generation from rotating a steam turbine collecting the residual heat of the exhaust gas. In addition, as combined cycle power generation comprises small gas turbines and steam turbines, operation /stoppage can be immediately switched and can be operated in response to changes in demand.
