Mitsubishi wins coal-fired power plant refurbishment contract in Mongolia

Mitsubishi Hitachi Power Systems (MHPS) has received a contract to upgrade eight units at what is claimed to be Mongolia’s largest coal-fired power plant.

Under the contract, MHPS will partner with Mongolia-based engineering firm, MCS International, to undertake the refurbishment work including addition/renewal of related equipment at on eight units at the thermal power plant in Ulaanbaatar.
The Ulaanbaatar Thermal Power Plant No.4 upgrade is set to be completed by October 2018.

Backed by a Japanese ODA loan from the Japan International Corporation Agency (JICA), the re project is aimed at improving the efficiency and service life of the power plant.

In particular, MHPS will renew the core components of the coal pulverizers in units No. 5 through No. 8 to extend their service life.

Designed to grind coal into fine particles and remove coarse-grained particles to ensure high thermal efficiency of boiler units, the coal pulverizers will help in reducing nitrogen oxides and other emissions.

The firm will also integrate soot blowers to all units from No.1 to No. 8 to prevent fall-off in heat-exchange efficiency. The Soot blowers are designed to help maintain efficiency of heat exchangers by removing soot and dust from boilers and other equipment.
