Retrofit Options for 660 MW Pure Condensing Turbine Exhaust Heating
Taking a 660 MW unit as an example,this paper analyzes and calculates how the operation safety and economy of boiler,turbine and auxiliary equipment is influenced by the three options,namely,the extraction steam heating of the reheater hot section,the extraction steam heating of the reheater cold section,and the extraction steam heating with press regulator of the pure condensing unit.The results show that the extraction steam heating with press regulator produces the best effect.And this heating method can reduce the steam cold source loss and increase the unit economical efficiency.
