BaoTou Steel Group BaoShan Thermal Station
Waste Heat Recovery (EMC) Project
Project location: Baiyun Ebo Baotou Steel BaoShan Mining Company Thermal Station
Equipment selection: 2 unit 42.7MW steam LiBr absorption heat pump
Main function: District heating
General introduction
The thermal power station of Baoshan Mining Company of Bao Steel is equipped with two low pressure steam heat pump units. The steam extraction of the steam turbine is used as the driving heat source to recover the waste heat from exhaust steam condensation of the steam turbine and raise the district heat water return to 77.9°C.Then it entered the first heating station to further increase the heat district heat water temperature to 85°C, which was used for the heating supply of Baoshan and Barun Mining Company, replacing the Barun hot water boiler house.
Technical Data
Heating capacity: 42.7MW/unit
Driven steam pressure: 0.4-0.6MPa(G)
Qty: 2 unit
COP: >1.8
District heating water: 77.9/60°C
Dimension: 10000*4720*5750mm
Low pressure steam: 15kPa (A)
Operation weight: 108t/unit
Steam consumption: 27.87t/h
Efficiency
Two unit 42.7MW heat pump units recovered 36MW waste heat from steam, compared with the boiler heating system, the steam consumption was saved by 60.2t/h. Calculated based on the central heating cycle of 7 months, the heat pump heating system could save steam amount of 303448t/y, save standard coal 30,000 tons/year, and reduce carbon dioxide emissions by 7.96 tons/year. Finally, economic benefits and social benefits can be achieved.
