摘要： 分析了现役煤电机组综合升级改造后的能耗、环保和运行可靠性状况，基于此分析了制约煤电机组系统寿命
的关键因素。通过典型机组案例计算，从度电经济成本和度电污染成本角度分析了新建机组和现役机组延续运行的经济
性。综合得出，中国现役煤电机组有足够的能力和可靠性延续运行，且现役煤电机组延续运行的经济性优于新建机组。

Abstract: This paper analyzed the status of energy consumption, environmental protection and operational reliability after
comprehensive upgrade and reconstruction of active coal-fired power generating units, and analyzed the key factors that limit the
life of coal-fired power generating units. Through the calculation of a typical unit case, the economics of the continued operation
of the new unit and the active unit were analyzed from the perspective of the economic cost of the units and the pollution cost of
the units. It is concluded that active China's coal-fired power generating units have sufficient capacity and reliability to continue
operation, and the economics of continued operation of active units is better than newly built units.

Key words: coal-fired power generating units; equipment status; continuous operation; status evaluation
