Yokohama, February 8, 2016 -- Mitsubishi Hitachi Power Systems, Ltd. (MHPS) has received an order to refurbish eight units at the Ulaanbaatar Thermal Power Plant No.4, State Owned Stock Company, which is Mongolia's largest coal-fired thermal power generation plant. MHPS will implement the refurbishment work in cooperation with MCS International LLC, Mongolia's largest engineering company. Refurbishment work is slated for completion in October 2018.

The project, which is financed by a Japanese ODA loan from the Japan International Corporation Agency (JICA), is aimed at improving the power plant's power generation efficiency and extending the facility's service life. The refurbishment, including addition/renewal of related equipment, will be performed on eight power generation units at the thermal power plant in Ulaanbaatar. More specifically, core components of the coal pulverizers in units No. 5 through No. 8 will be renewed to extend their service life, while soot blowers will be added to all units from No.1 to No. 8 to prevent fall-off in heat-exchange efficiency. When completed, the refurbishment is expected to contribute to the realization of a more stable power supply.

Coal pulverizers are used to grind coal into fine particles and to remove coarse-grained particles to ensure high thermal efficiency of boiler units. Coal pulverizers also help reduce NOx (nitrogen oxides) and other emissions. Soot blowers remove soot and dust from boilers and other equipment to help maintain efficiency of heat exchangers.

Led primarily by the development of mineral resources, the Mongolian economy has expanded in recent years. Accompanying this economic growth, power demand in the metropolitan area has increased rapidly, creating an urgent need to strengthen power supply capacity. At many existing power generation facilities, however, antiquated equipment has caused power generation efficiency to deteriorate, and raised concerns about adverse affects to the environment. Through this refurbishment to improve power generation capacity, MHPS hopes to continuously contribute to the development of Mongolia's economic expansion.

By leveraging its broad array of products and services going forward, MHPS will continue to respond to a variety of market and customer needs for thermal power generation systems.
