Our Business / Thermal Power StationsTypes 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. Steam with hot and high pressure 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, which activates a generator, connected to the turbine, to generate electricity. Steam power generation uses the 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 the use of a gas turbine and a steam turbine.
A high thermal efficiency can be achieved by combining these two methods of power generation: gas turbine power generation by rotating the generator by using the expansion power of combustion gas generated by burning fuels inside compressed air, and steam power generation by rotating the steam turbine by using the collected residual heat of the exhaust gas. Additionally, due to composition of small gas turbines and steam turbines, operation / stoppage can be immediately switched, which quickly responds to necessity.
