通过煤质如挥发分、发热量、灰分的变化以及不同煤种掺混燃烧、石子煤、煤质下降等情况对锅炉经济性的影响分析,提出电厂动力配煤的经济评估策略。建议综合考虑锅炉性能、机组效率、燃料价格等多方面的因素做为电厂采购经济煤种的依据。 Based on the analysis of coal quality, such as volatile matter, calorific value and ash content, as well as the influences of different types of coal blending and combustion, stone coal and coal quality declining on economy of boiler, the economic evaluation strategy of power plant coal blending is put forward. Proposed comprehensive consideration of boiler performance, unit efficiency, fuel prices and many other factors as the basis for the procurement of coal power plant economy.
