Abstract:

Abstract:Along with the increased environmental protection efforts,a large number of construction projects are put into heat supply in recent years.According to the implementation of heating plant project in Jiangsu Huadian Wangting Power Plant,the background and characteristics of the unit heating mode are analyzed,and such transformation measures as the low pressure communication pipe,induced draft fan and booster fan merger,and four steam extraction are come up with.The data shows the efficiency of the unit and energy efficiency are improved after the transformation through the analysis of energy saving and environmental benefits.
