MHPS receives order to upgrade environmental systems

12 June 2018

Mitsubishi Hitachi Power Systems, Ltd., (MHPS), jointly with its group company Mitsubishi Hitachi Power Systems Environmental Solutions, Ltd., has received an order for environmental systems upgrade work at Unit 3 of the Boryeong Power Station operated by Korea Midland Power Co., Ltd. The upgrade is targeted at reducing emissions of sulfur oxide (SOx), nitrogen oxide (NOx) and particulates in line with the Korean Government's drive to curb air pollution caused by the nation's coal-fired power plants. The new systems are scheduled to go into operation in August 2019.

The Boryeong Power Station is located in the city of Boryeong, South Chungcheong Province, on Korea's west coast, approximately 140 km south-southwest of the capital, Seoul. The plant was launched in 1983 and has an output of 4,800 megawatts. Unit 3, designated for upgrading, has an output of 550 MW. Engineering, procurement and construction will be performed by STX Heavy Industries Co., Ltd., a Korean company with which MHPS has a technical tie-up in flue gas desulfurization systems.

The scope of the order calls for the MHPS group to: 1) supply the core parts for upgrading the FGD equipment, in order to improve the SOx removal rate; 2) deliver a denitration catalyst enabling outstanding NOx reduction; 3) revamp the electrostatic precipitator to enhance the particulates removal rate; and 4) perform engineering of a non-leak gas-gas heater (NL-GGH) enabling heat exchange and flue gas reheating.
