摘要
Abstract
When thermal power heating units participate in peak shaving operation,how to meet the steam demand of heat consumers under low load condition of steam turbine is a topic worthy of research.Taking the heating condition of a 350 MW thermal power unit with low load as research objective,a scheme for intermediate pressure control valves to participate in heating regulation was proposed.By changing the open angle of the intermediate pressure control valves,the steam pressure for external heating could be adjusted,and the real-time matching of steam parameters to the demand of heat consumers could be realized.Therefore,the problem of low pressure of heating steam caused by peak shaving operation was successfully solved,and the unit was enabled to have heating capacity at the load range of 40%-100%.The implementation results of this scheme showed that the unit could meet the steam demand of heat customers during peak shaving operation,thus the engineering application value of this scheme was verified.The research results can provide reference for the design of optimization schemes to realize heating goal during peak shaving operation for thermal power heating units of the same type.关键词
