近几年,R型低压燃油烧嘴以雾化质量好,火焰较短、调节比例大等特点,在耐火材料工业中得到广泛地应用。但随着直接结合的碱性耐火制品的比例增大,R型低压燃油烧嘴无法满足高温熔烧的要求。就目前国内而言,要实现1700℃以上的高温,均是采用高压烧嘴以优质的燃料来实现,但高压烧嘴造价昂贵,设备复杂,维修困难,本试验用国产200~#重油作为燃料,采取技术措施并模拟隧道窑正常焙
In recent years, R-type low-pressure fuel burner to atomization of good quality, short flame, adjust the proportion of large and other characteristics, in the refractory industry has been widely used. However, with the increase of the proportion of basic refractory products directly combined, the R-type low-pressure fuel burner can not meet the requirements of high-temperature melting. At present, in order to achieve high temperatures above 1700 ℃, high-pressure burners are used to achieve high-quality fuel. However, high-pressure burners are expensive, complicated in equipment and difficult to maintain. In this experiment, domestic 200 ~ # heavy oil is used as fuel , Take technical measures and simulate the normal baking tunnel kiln
