Optimal operation of cold end system for steam turbine in coal-fired power plant

The optimal operation of cold end system of steam turbine is an important measure to saving energy in power plant. This article takes the cold end system of steam turbine in coal-fired power plant from actual conditions, in determining the optimized vacuum and optimized cooling water flow, many factors such as economy, thermal pollution cost and water fee of cooling water have been considered. So it is more fit to reality. In the course of study, taking the domestic 600MW unit as an example, the optimal operation of cold end system of steam turbine is analyzed and calculated.
