Gwangyang Off-Gas Combined Cycle Power Plant

_{Korea’s first Off-Gas Combined Cycle Power Plant}

Power Plant Overview

The Gwangyang Plant, the nation’s first of its kind to be built, was completed in December 2010.
Its total installed capacity reaches 284MW. Off-gas combined cycle power plant in Gwangyang where they produce electricity by
using the off-gas as fuel is an eco-friendly power plant that has the replacement
effect for the import of crude oil amounting to 57 billion won annually and 180,000 ton of greenhouse gas reduction effect.

Pohang Off-Gas Combined Cycle Power Plant

_{The world’s first to produce electricity using the fuel combining
BFG(Blast Furnace Gas) and FOG(FINEX Off-Gas)}

Power Plant Overview

The Pohang Plant, the world’s first to produce electricity using the fuel combining BFG(BlastFurnace Gas)
and FOG(FINEX Off-Gas), is equipped with facilities with total installed capacity of 290MW.
FOG generated from the FINEX plant is high in generating efficiency as its standard heat is higher than BFG.

In addition, off-gas combined cycle power plant in Pohang introduced a nitrogen oxide reduction device and minimized pollutants by
establishing the internal management standard (30 ppm) that is more tightened than the legal management standard (50 ppm)
and is now taking the lead in improving the atmospheric environment.

The Principle of Off-Gas Combined Cycle Power Generation

제철소: 제철공정에서 발생하는 부생가스를 연료로 공급합니다. 발전소: 가스압축기를 통해 부생가스를 압축,공금하여 가스커빈에서 1차전력을 생산한 후, 배출되는 고온의 배기 가스를 회수하여 스팀터빈에서 2차 전력을 생산합니다.
