第十一冶炼厂原有的焙烧窑热效率较低,仅为32%,生产能力也较低。针对这个问题,去年,由老工人、技术人员、领导干部三结合,经一年多的试验,革新制成了高效率的蜂窝式热交换器,使焙烧窑的生产能力提高了28%,热量消耗降低了约15%,窑尾温度由原来的472℃降至270％,每年能为国家节约42万元。 Eleventh smelter original roaster kiln thermal efficiency is low, only 32%, the production capacity is also low. In response to this problem, last year, the combination of old workers, technicians and leading cadres, after more than a year’s trial, made a high-efficiency honeycomb heat exchanger, which increased the production capacity of roasting kilns by 28% The consumption has been reduced by about 15%. The temperature of the kiln tail has dropped from 472 ℃ to 270%, which saves 420,000 yuan for the country each year.
