Thermal Power

Steam power generation

Fuels such as heavy oil, LNG (liquefied natural gas), and coal are burned inside a boiler to generate steam at high temperature and high pressure. This steam is used to rotate the impeller of the steam turbine. This drives the power generators connected to the turbine that generates electricity. This system has a thermal efficiency of around 42% to 46% and functions as a base-to-middle-load supply.

Combined cycle power generation

This method of generating electric power incorporates a gas turbine whose waste heat is reused to drive a steam turbine. The gas turbine is powered by high-temperature combustion gas that, after being discharged from the gas turbine, is efficiently recovered by means of a heat recovery boiler. This produces steam of sufficient temperature and pressure to drive the steam turbine and generate electricity. This configuration ensures high thermal efficiency, as the cost per unit of power generated is lower than that of oil-fired thermal power. It is used to provide the base-to-middle-load supply.

Gas turbine power generation

This electricity generating system makes electricity by burning fuels such as LNG (liquefied natural gas) or kerosene to produce high-temperature combustion gases with sufficient energy to rotate a gas turbine.
