Application Research on Power Plant Heat Pump Regenerative Thermal System

Abstract:

To recycle waste heat from circulating water, the model of the power plant heat pump regenerative thermal system is put forward, and the indexes of the system are analyzed. It is indicated in the specific case that the absorption heat pump has an advantage over the compression heat pump. Using the extraction steam of the low pressure cylinder as its driving heat source, economize on coal can be realized in the condition that the coefficient of performance(COP) of the heat pump is above the critical COP. For the case of the compression heat pump, the fuel efficiency is improved a little, but on the other hand, as the station service power is increased, the power supply coal consumption is increased too.
