The off-gas power plant generates power by using off-gases produced in steelmaking process. It is an eco-friendly power plant providing a substitute for crude oil imports worth 57 billion won and reducing greenhouse-effect gases of 180,000 tons a year.
The Off-gas Combined Cycle Power Plant uses a method in which a gas turbine generates electricity in the initial cycle by combusting off-gas. Then the HRSG recovers the waste heat generated from the gas turbine and produces steam. The steam is then used to drive the steam turbine which generates power.
