Analysis on benefit of circulating water waste heat recovery of 300MW heatsupply power unit by absorption heat pump

Abstract

Abstract: Abstract:The energy comprehensive utilization rate of 300MW heatsupply power unit under pure condensation condition and steam extraction for heat supply condition is lower, and the energy carried off by lowtemperature circulating water is more than 30% of the total energy consumption of the unit. A waste heat recovery scheme was proposed, in which a steamtype lithium bromide absorption heat pump is used to recover the waste heat of circulating water of heatsupply power unit. Taking a power plant as example, the waste heat recovery capability of the heat pump and the thermal economic efficiency of the whole power plant were calculated in detail. The result shows that to use heat pump to recover waste heat of circulating water of heatsupply power generation enterprise can obtain benefits of both energy conservation and environment protection.
