There are several heating schemes for different condensing units changed to heating reconstruction, by comparing the advantages and disadvantages and scope of different heating schemes,the medium and low pressure connecting pipe heat extraction is accepted as 600 MW supercritical condensing unit heating scheme. On this basis,comparatively analysis the characteristics of different driving modes of circulating heating pump, and annual cost analysis method is used to focus on the economy about industrial steam turbine-driven and fre-quency control motor-driven,consider that the industrial steam turbine-driven circulation heating pump can significantly reduce the power consumption rate,and improve economic efficiency of the power plant,better economic benefits in the former case where the same amount of power.
