Optimization of the Valve Inlet Mode for 880MW Steam Turbine in Suizhong Power Plant
Although the steam passage part of the 880MW steam turbine unit in Suizhong Power Plant has undergone modern reformation,the control valve,steam inlet mechanism,control form have not been reformed yet,and the original operation mode of single valve is still in use,which has a significant impact on the unit efficiency.This time,by optimizing the valve opening sequence,optimizing the overlap degree of flow curves,carrying out a large number of bearing load theoretical calculations,conducting optimization research on different steam inlet methods of the valves,recommending reasonable unit operation modes,we solved the problem of single valve being unable to switch,which achieved the expected effect and improved economic efficiency.It has high application and promotion value in similar steam turbine units.
