在有色冶金工厂中,各种冶金炉的热能利用率是很低的,有很大一部分热能被烟气带走;同时为保证冶金炉的正常运行和延长使用寿命,通常采用水冷却的方法,冷却水又带走大量热能。我厂0.5米~2的杂铜熔炼鼓风炉,烟气逸出时的温度高达900～1000℃,水套冷却水(60℃)每昼夜就有360吨白白流掉。面对着大量热能和水的浪费,老工人 In the non-ferrous metallurgical plants, various metallurgical furnace thermal energy utilization rate is very low, a large part of the heat away from the flue gas; the same time, to ensure the normal operation of metallurgical furnace and extend the service life, usually using water-cooled method, Cooling water and take away a lot of heat. I plant 0.5 m ~ 2 of copper smelting blast furnace flue gas escape temperature of up to 900 ~ 1000 ℃, water jacket cooling water (60 ℃) every day and night there 360 ​​tons of vain flow out. The face of a lot of heat and water waste, the old workers
