【Abstract】 The nonstationary state heat transfer of industrial furnace with multilayer wall has been calculated by finite difference method. The formulas for computing temperatures on interracial and outer surfaces and temperature field within the layers under condition of nonstationary state heat transfer are suggested. A calculation instance was carried out. The results indicate that the temperatures calcutad on the outer surface are in good agreement with that of the measured ones.更多还原
