摘要
切缸供热机组的调节能力受实际运行参数的影响,设计抽汽工况图不能准确反应机组的实际调节性能,为解决上述问题,以某300 MW切缸供热机组为例,通过调节能力试验得到机组在不同运行方式下的实际调峰能力与供热能力,并与设计抽汽工况图进行比较,分析实际值和设计值偏差的原因,为发电企业运行调度提供参考。
The regulation capacity of the cylinder cut-off heating unit is affected by steam extraction parameters.The design steam extraction working condition diagram can not accurately reflect the actual regulation performance of the unit.In order to solve this problem,take a 300 MW cylinder cut-off heating unit as an example,the actual peak shaving capacity and heating capacity of the unit under various operation modes are obtained through the regulation capacity test,and compared with the design steam extraction working condition diagram to analyze the reasons for the deviation between the regulation actual value and the design value,so as to provide reference for the operation dispatching of power generation enterprises.
