Mitsubishi Hitachi Power Systems (MHPS) has secured an order for a refurbishment of eight units at fourth thermal power plant in Ulaanbaatar, Mongolia.
The company will carry out refurbishment work at the country’s largest coal-fired thermal power generation facility, with support of engineering firm MCS International.
MHPS plans to complete the refurbishment work at the thermal power plant by October 2018.
Japan International Corporation Agency (JICA) has financed the project, which will help to enhance the facility’s power generation efficiency and service life.
The refurbishment will include the addition and renewal of related equipment on eight power generation units at the thermal power plant.
The firm will renew the core components of the coal pulverisers from units No. 5 to No.8 to extend their service life.
It will also add soot blowers to all units to prevent fall-off in heat-exchange efficiency.
According to MHPS, the refurbishment will help in the realisation of a stable power supply.
Coal pulverisers will be used to grind coal into fine particles, in addition to removing coarse-grained particle for high thermal efficiency of boiler units. These will also allow in reducing NOx (nitrogen oxides) and other emissions.
Soot blowers enable in removing soot and dust from boilers and other equipment, helping to enhance efficiency of heat exchangers.
