摘    要:阐述了火力发电厂汽轮机旁路系统工质内部泄漏的原因,并结合电力行业标准DL/T606.3-2006火力发电厂能量平衡导则第3部分:热平衡的新要求,运用考虑管道热效率的等效热降法对某引进型300 MW机组进行了热经济性分析.对电厂节能工作提出了积极建议:针对机组旁路内漏问题,应充分考虑其变化对管道热效率及机组绝对内效率产生的影响,以全厂热效率的变化作为衡量经济性的最终指标.

关 键 词:火电厂  旁路内漏  节能  管道热效率  等效热降法  反平衡方法

Abstract:The reason of inner leakage of the working medium in steam turbine bypass system in the power plant was expounded.The thermal economical efficiency analyze was carried out for one imported-type 300 MW unit by equivalent enthalpy drop method(EEDM) considering the thermal efficiency of the pipeline and combining with the new requirements of power industrial criterion DL/T606.3-2006 "Guide for energy balance of thermal power plant Part 3: Thermal energy balance".The constructive energy conservation suggestions...
Keywords:power plant  bypass inner leakage  energy conservation  piping thermal efficiency  equivalent enthalpy drop method  anti-equity method
