竖窑烟气和冷却带的余热利用

Waste Heat Energy Utilization of Flue Gas and Cooling Zone of Kiln

竖窑在煅烧料石的过程中,因排烟温度和料石出窑温度较高,生产工艺中存在较多的热量浪费。通过制作换热器、接装铺设抽热风管路等,对竖窑排烟与冷却带进行改造,从而收集部分余热用于料坯烘干和洗浴用水加热,全年节约成本近200万元。

In the process of calcining the kiln, due to the higher temperature of the smoke exhaust and the kiln, there is a lot of heat waste in the production process. Through the reconstruction of the smoke and cooling zone of the shaft kiln, the waste heat can be collected for heating of the billet drying and bathing water, and nearly 2 million Yuan cost is saved for the whole year.
