The principle of wasteheat utilization to save energy in the two-stage drying pro-cess is introduced.
简述了节能两级干燥工艺流程利用余热的基本原理。
2
The air velocity of the improved drier is homogeneous and the waste gas and heat energy can be recycled reasonably, and the drying can be completed once.
改进后的干燥机，热空气流动均匀，废气热能合理回收利用，能一次完成干燥。
3
The exchanger is used to recover the wasteheat of the flue gas from enamelling furnace, in order to preheat the air entering the drying oven. Good results in energy saving have been obtained.
