| Abstract: | In this paper, the present situation of waste heat recovery in the power plant is firstly introduced. The scheme of applying a large-scaled CO2 heat pump for heating in the power plant is then advanced based on the comparative analysis of the advantages and disadvantages between the LiBr absorption heat pump and the CO2 heat pump. Based on the comparison among the extraction heating, the compression heat pump and the absorption heat pump, the strengths and needs of using a steam turbine to drive the CO2 heat pump are discussed. This is followed by the analysis of the problems may be encountered in the application of the large-scaled CO2 heat pump. Finally, the development trend of the utilization of heat pump in the power plant is evaluated. |
