Datong No.1 Thermal Power Plant Exhaust Steam Waste Heat Utilization Demonstration Project

• Increased heating: 130MW
• Annual waste heat recovery: 1.79 million GJ
• Increased heating area: 2 million m2
• Annual standard coal savings: 80,000 tons

The project adopts “central heating technology based on cogeneration”, adds two waste heat recovery dedicated heat pump units in Datong No. 1 Thermal Power Plant, recovers the waste heat of the power plant’s steam turbine, and provides heating for the shantytowns and subsidence areas of Datong Coal Mine Group. At the same time, absorption-type large temperature difference heat exchange units are installed in some heat exchange stations, increasing the heating capacity of the first station by 49% and the heating capacity of the heat network by 38%. The renovation project meets the building heating needs of 6.38 million m2 in the “two districts” of Datong Coal.
