摘要
蓄热装置是太阳能热发电系统中的关键部件之一。对混凝土蓄热装置的传热过程进行了模拟研究,得到了混凝土蓄热器内部的温度等特征参数,并对影响因素进行了分析,结果表明混凝土较大的导热系数有利于提高蓄热温度,导热油进口温度和速度较大的时候,明显提高了换热效果,增加了蓄热装置的蓄热量。
Thermal storage device is one of the key components in the system of a solar thermal power. In this paper, the heat transfer process of a concrete thermal storage is simulated and analyzed. The temperature distribution of the system is obtained and the influence factors are analyzed. When the thermal oil has bigger inlet temperature and velocity, the heat transfer effect is improved significantly, increasing the total thermal storage capacity of the system.
