炉墙为辐射绝热面时炉内辐射换热计算的误差分析

Calculation Error Analysis for Radiation Heat Transfer in Furnace with Radiation Insulation Furnace Wall

分析了炉墙为辐射绝热面时对炉内加热制品表面辐射热流和炉墙内表面温度所造成的误差,讨论了影响这种误差的一些因素,对火焰直接加热炉和间接加热炉(如辐射管炉或电阻加热炉)分别进行了分析和讨论。

Calculation errors for radiative heat transfer flux of heated stock and for furnace wall temperature with assumption of radiant insulation furnace wall were analyzed for fuel-fired furnace and radiant tube furnace.
