入炉煤低位发热量变化对机组经济性的影响

Effect of changing of coal low heat value on economy of generating unit

入炉煤低位发热量变化对机组热经济性有很大影响。分析了煤中灰分和水分变化对入炉煤低位发热量变化和机组热经济性的影响,通过对220 t/h锅炉的计算和分析,定量地给出了入炉煤低位发热量变化和机组热经济性之间的关系,对火力发电企业节能降耗具有参考作用。

The changing of net calorific valve input has a great impact on thermal economy of generating set. The effect of changing of ash and water content in coal on the changing of net calorific value input and thermal economy of generating unit was analyzed, the relationship between them was quantitatively given through calculation and analysis for 220 t/h boiler, which has a useful reference to saving energy and decreasing consumption.
