Possibility analysis of hot pollution recycle in heat machining workshop
热加工车间热污染回收能力分析

According to the characteristics of huge physical volume and large surface of industrial furnace in heat machining workshop, a leading flow cover was adopted to make the hot air near furnace wall into heat exchanger and the heat recycled. There are three advantage points of furnace wall heat keeping, environmental beautification and valid air current organized by using the leading flow cover. According to the basic principle of heat transfer, the exhausted quantities of hot pollution with two ways of bare furnace wall and furnace +leading flow cover were analyzed, and the basic calculation formula of heat quantity was gained. To take certain steel rolling heat furnace for example, after the hot pump recovery technology is adopted, the hot pollution will be reduced 90%, and 404 kW of heat can be reclaimed, the heat pollution to ambience will be greatly decreased.
