摘 要：通过对某电厂年度能耗指标完成情况的分析， t/h,未达
到Ot/h的机组设计值，存在节能优化空间。对机组再热减温水流量大问题的原因进行了分析，明确了机组存在再
热器两侧烟温偏差大、再热减温水调门内漏、再热减温水流量测点显示零点偏差等3 个问题，并进行针对性治理，
t/h左右，基本上达到设计值水平。

Cause analysis and treatment of 600 MW unit's reheating and desuperheating water volume
not reaching the design valuet
LI Xiao-jie
Abstract： Through diagnostic analysis of the completion of the annual energy consumption indicators of a power plant, it
is found that the average annual completion of the reheating and desuperheating water volume of the unit is t/h, which
does not reach the unit design value of 0 t/h, and there is room for energy-saving optimization. The reasons for the large
reheat desuperheating water flow problem of the unit were analyzed, and it was
