Calculation of Heat Losses from the Outer Surface of a Furnace Enclosure

Resumo

Relations obtained from an analysis of published data and as a result of mathematical modeling of a glass furnace are presented for calculating the heat flux density into the environment from the outer surfaces of the enclosure of an industrial furnace — sidewalls, roof, and hearth. On the basis of a comparative analysis of these relations for a glass furnace recommendations are formulated for selecting and using relations for calculating the coefficients of heat emission from the outer walls of the enclosure for the purpose of making a better determination of the heat balance of a furnace.
