The performance test of low vacuum circulating water hea ting for 200MW combined cycle unit is carried out, and its economic performance is analyzed. The experimental results show that provide the same heating load amount of 53MW by low vacuum circulating water heating for 15.9KPa of unit backpressure and steam heating,low vacuum circulating water heating relative to the pumping steam heating to increase the generating capacity of 8.849MW. Experiment of low vacu-um circulating water heating under different backpressure, analysis of the different backpressure on the heating water tem-perature rise, heat absorption of heat water, steam turbine thermal efficiency, heat consumption of steam turbine and the in-fluence of the influence of steam turbine power generation.
