Optimization of Regenerative Stage Numbers for 1 000 MW Wet Cooling Units

Abstract

Abstract

To optimize regenerative extraction steam system for turbine-generator units and cycle heat efficiency, the reasonable regenerative stage numbers should be determined according to the turbine structure and boiler feed water temperature. Based on the characteristics of 1 000 MW single-reheat and double-reheat wet cooling turbine, constraints of the regenerative stage numbers and unit economy, the optimization of regenerative stage numbers are stated. The results show that the optimization of regenerative stage numbers for 1 000 MW single-reheat and double-reheat wet cooling turbine are nine level and ten level.
