摘　　要：为实现热电解耦,可通过在热电厂配置大型蓄热水罐,在供热负荷低时将多余热量储存在水罐中,在供热负荷高时将热量释放出来,从而提高火电供热机组深度调峰能力。为确保蓄热水罐在充放热过程中有较高的运行效率,必须保证罐内斜温层的稳定。本文对某大型蓄热水罐进行了流动传热模拟,验证了水罐结构及布水器设计的可行性,为蓄热水罐设计提供一定参考。In order to achieve the aim of thermo-electric decoupling,the large scale thermal storage water tank can be installed in the thermal power plant.In w hich,the thermal energy can be stored in the tank when the heat demand is low,and the thermal energy can be released when the heat demand is high.By this w ay,the deep peak-shaving capacity of thermal power plant will be improved.The thermocline should be kept stable in the process of charging and releasing heat for sake of high operating efficiency.In this p ap er,flow and heat transfer simulation is carried out to check the feasibility of a large scale thermal storage water tan k,which provides a reference to the design of large storage tank.
