Specialists from the National Research Institute for Mechanical Engineering - NARIME (Ministry of Industry and Trade) have successfully researched, designed and made a rotary heat recovery air dryer for boiler in coal-fired thermal power plant.

This is a heat exchanger arranged behind the boiler to salvage heat of exhaust fume to heating air provide for fuel combustion, in order to improve the thermal efficiency of the boiler in coal-fired thermal power plant.

This research is considered as an important contribution to improve localization capability in supplying and installing air dryers in coal-fired thermal power plants with a capacity up to 300MW, and create conditions for businesses to save costs in localization of the large mechanical equipment.

The product is in tested operation at Hai Phong Thermal Power Plant.

NARIME is a state research and development agency on science and technology in mechanical engineering field with 15 units specialized on research, design, consultancy manufacture… Thermal power is an important part of the works that NẢIME was and is implementing.

NARIME, recently, has been restored, replaced a lot of important spare parts with a high economic value and replacing imported ones as bearings for coal grinding machine, bag dust filtering system, motors, generators… in accordance with requirements of thermal power plants.
