摘要
本文描述了顺流辐射换热器的数学模型。应用本模型着重计算分析了端部辐射,壁面辐射率、换热器长度、烟气入口温度及空气流速对换热过程的影响,从理论上分析了辐射换热器的换热机理。
A mathematical model of the parellelflow radiation heat exchanger is introduced in this paper. Based on the mathematical model, this paper studys the effect of end radiation, emissivity of wall, length of exchanger, entrance temperature of flow gas and velocity of air, on heat transfer. The heat exchang mechanism of radiation exchanger is also stuied.
