针对锻铸车间热处理炉能耗较高,经过传统的一次余热利用预热助燃空气后仍产生较大的热损失等问题,设计了高温废气二次回收利用系统,阐述了锻铸车间高温烟气余热二次利用系统的组成,对烟气余热收集、软化水制取、热量主循环、热水制取、采暖及生活用水供应系统,以及自动化控制等做了介绍。通过现场运行情况可知,该系统对于提高热处理炉热效率、完善热处理工艺、节能环保等有明显的作用。
In view of the high energy consumption of the heat treatment furnace in the forging shop, the heat loss after the preheating of the combustion air by the traditional primary heat recovery is still a problem. The high temperature exhaust gas recovery and utilization system is designed and the high temperature flue gas Waste heat secondary use of the composition of the system, the collection of flue gas waste heat, made of demineralized water, the main heat cycle, hot water system, heating and domestic water supply systems, and automation control were introduced. Through the field operation shows that the system for improving the heat treatment furnace thermal efficiency, improve the heat treatment process, energy saving and environmental protection have a significant role.
