【摘要】 以等效焓降理论为基础,考虑不同负荷汽态线的变化,建立了各级加热器端差对机组经济性影响的在线计算模型。通过本计算模型可以在线计算各加热器端差对机组热经济性的影响,从而指导运行和检修,提高电厂运行的经济性。更多还原

【Abstract】 Based on the theory of equivalent enthalpy drop, This paper established online analysis model of each stage feedwa-ter heater terminal temperature difference effect on operation efficiency, concerned about steam expansion line changes at different load. The model makes it possible to online appraise each feedwater heater terminal temperature difference effect on thermal efficiency, then guides operation and maintenance to improve efficiency of thermal power plant unit.更多还原
