热电厂储热罐系统建模与斜温层厚度的数值模拟研究

Research on Energy Storage System Modeling in Thermal Power Plant and Numerical Simulation of the Thickness of Thermocline Layer

目前给热电供热机组配置热水储热罐可实现"热电解耦",提高机组调峰能力,而斜温层厚度是评价热水储热罐储热效率的一个重要指标。为此,以常压热水储热罐储热过程为例,通过建模与数值模拟研究了入口混合因子对储热罐斜温层厚度的影响。

At present, the thermoelectric heating unit equipped with hot water storage tank can realize "thermoelectric decoupling", which improves the capacity of unit peak regulation. The thickness of the thermocline layer is an important index for evaluating the thermal efficiency of the hot water storage tank. In this paper, taking the heat storage process of atmospheric pressure hot water storage tank as an example, the influence of the inlet mixing factor on the thickness of thermocline layer of the heat storage tank was studied by modeling and simulation.
