摘要
选择北方某热电厂330 MW热电机组,研究其耦合热水储热调峰的能耗特性.结果显示,热负荷为300 MW时,储热调峰条件下机组最低发电负荷可减少62.76 MW,相比原机组降低了27.7%,机组深度调峰能力得到提升;机组配置储热装置后,最大能量利用效率和最大㶲效率均有所增加;机组应用热水储热装置调峰运行后,在某典型日的总煤耗可以减少23.48 t/d.
Abstract
A 330 MW thermal power unit from a thermal power plant in northern China was selected to study its energy consumption characteristics coupled with hot water storage and peak shaving.The results show that when the heat load is 300 MW,the minimum power generation load of the unit can be reduced by 62.76 MW under the condition of heat storage peak shaving,which is 27.7%lower than that of the original unit,and the deep peak regulation capacity of the unit is improved.After the unit is equipped with a heat storage device,the maximum energy utilization efficiency and maximum efficiency are increased.After the unit is operated by hot water storage device for peak shaving,the total coal consumption can be reduced by 23.48 t/d on a typical day.
