摘　　要：间歇式炉由于在加热过程中烟气温度不断变化 ,换热器换热系数及空气预热温度也不断变化 ,故必须以整个加热过程为计算对象对换热器进行计算。In heating process of the intermittent furnace,flue gas temperature,heat exchanging coefficient of exchanger and air preheating temperature changed continually,so we must calculate heat exchanging area regarding the whole heating process as object.Here we took radiation exchanger for example and showed the calculation of economical heat exchanging area of exchanger used in intermittent furnace.

关 键 词：间歇式炉 换热器 计算 换热面积
