Analysis and Optimization of Low Vacuum Value of Condenser in a Power Plant
The condenser vacuum value is an important safety parameter for the operation of the conventional island in a power plant.Excessively low condenser vacuum values and excessively high humidity of the final-stage steam in the steam turbine can damage the final-stage blades,jeopardizing the safe operation of the turbine set.During the power generation operation of a power plant in 2015,the vacuum value of the condenser in the conventional island remained at a low level.In 2016,a cause analysis was carried out for the issue of reduced condenser vacuum in the turbine unit,and optimization measures for the condenser vacuum system were formulated and implemented.These measures were effectively verified during the operation in 2020,ensuring operational safety.
