摘要
为改善原镁砂加热炉体积、热效率、耗能及环境污染等各项指标,采用等强度对流和二次燃烧原理,对镁砂加热炉进行了重新设计和制造。使新型镁砂加热炉比旧炉横截面积减小4.4倍,高度减小2.6倍,产量提高3～5倍,节煤33％～50％,生产环境大大改善,经济效益大幅度提高。新型镁砂加热炉在耐火材料生产、建筑行业砂石料加热及其他颗粒物料干燥加热有广泛的推广应用价值。
The magnesite heating furnance has been redesigned and manufactured,with the princi- ple of equicohesive convection and secondary combustion,for the improvement of the vol- ume,thermal efficiency,power-waste and pollution.The new type of magnesite hesting fur- nance is 4.4 times diminish in cross-section area,2.6 times depression in height,3～5 times increase in yield,coal save 33%～50%,good working environment and better economic ef- fect than old ones.It has wide use also in sand heating of construction and others.
