Thermal Insulation Performance Analysis of a Fire-resistance Tests Furnace Based on Numerical Calculation
Fire resistance test furnace is the key equipment to test the fire resistance of structures/accessories,usu-ally consumes a lot of fuel to maintain(2～3)h high temperature test conditions.In this paper,a three-dimen-sional heat transfer numerical calculation model is established for the thermal insulation structure of the furnace,and the numerical results are compared with the theoretical calculation results to verify the accuracy of the model.At the same time,the temperature distribution of the furnace structure of different schemes is obtained by numerical calcu-lation,and the temperature performance of the insulation layer and the outer protective layer is compared under the same furnace temperature condition,so as to get the best scheme.
