Three-dimensional Numerical Modeling of Cooling Water Jacket of Pot Calciner

为了提高罐式煅烧炉冷却水套的换热效率,介绍了罐式煅烧炉的工作原理。根据CFD有限元法,结合自编程序对冷却水套内部的流场及温度场进行了三维模拟,计算了不同流量0.75 kg/s、0.87 kg/s和1.00 kg/s工况下的换热效率。结果表明,当罐式煅烧炉单罐产能为120 kg/s,流量为0.87 kg/s时冷却水套具有最优的综合换热效率。

The working principle of pot calciner is introduced which purpose is improve the heat exchange efficiency of cooling water jacket of pot calciner. The three-dimensional modeling of the inside flow field and temperature field of cooling water jacket is carried out combining with the self-programming software and according to the CFD finite element method, the heat exchange rate are calculated as per the different flow 0.75kg/s、 0. 87kg/s 、1.00kg/s. The results show, when the yield of single pot calciner is 120kg/s, the flow is 0. 87kg/s, the cooling water jacket has the best comprehensive heat exchange rate.
