摘要
介绍了间接换热式高温热风炉的设计及结构。该炉采用两级换热以获５５０℃以上高温热空气，采用有效隔热保温结构及材料、余热利用、降低烟气排出温度等措施，热效率达７５％以上。
In order to dry some agricultural products(such as green forage)which are of highmoisture-containing ratio,the temperature of the drying rnedium must be over 400℃.Thispaper introduces the structure and design of the air-heating furnace of indirect heat transfer.The unit with two-stage heat transfer has been adopted in this furnace to enable the hot-airtemperature to be over 550℃,The thermal efficiency can reach over 75%by utilizing wasteheat,lowering the temperature of flue-gas and applying thermal insulation layer and materi-als.
