Our Business / Thermal Power StationsTypes and Mechanism of Thermal Power Generation

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.
