大型电站锅炉炉内温度场的数值试验研究

An Experimental Study of the Temperature Field Inside a Large-sized Utility Boiler Furnace by CAT

运用计算机辅助优化数值试验方法对大型电站锅炉内温度场的特性进行了基础性研究。通过对炉内介质辐射传热的三维数值模拟，得出锅炉炉内温度场分布的相应规律。多数数值试验的计算结果和实际的现场测试结果吻合较好。

Through the use of a computer aided test method a fundamental research is conducted of the characteristics of the temperature field in a large sized utility boiler furnace. On the basis of a three dimensional numerical simulation of the working medium radiation heat transfer in the furnace obtained is a pertinent in furnace temperature field distribution law. The numerical test results in most cases are in relatively good agreement with those of the on site tests.
