大型燃煤火电机组集中供热的节能减排效果分析

Analysis of Energy Saving and Emission Reduction Effect of Central Heating Supplied by Large Coal-fired Power Unit

为了调动用热企业采用集中供热热源的积极性,提高能源利用效率,分析大型燃煤火电机组集中供热的节能减排效果。分析、对比大型燃煤火电机组和小锅炉的经济性及节能减排效果,结果表明,大型燃煤发电机组热效率高,节能减排效果明显。最后针对大型燃煤机组负荷率低及汛期负荷低谷时段水电弃水量增加问题,提出了相关对策。

In order to arouse the enthusiasm of enterprises using thermal energy to choose central heating supply sources, and improve the energy utilization efficiency, the energy saving and emission reduction effect of central heating supplied by large coal-fired power unit is analyzed. The economy and the energy saving and emission reduction effect between the large coal-fired power unit and the small boiler are analyzed and compared. Results show that the large coal-fired power unit has higher thermal efficiency and more obvious thermal efficiency. Finally, aiming at problems including the lower load rate of large coal-fired power unit and the increasing discarding water of hydropower under low load period of time during the flood season, corresponding countermeasures are proposed.
