随着石油工业的技术进步，炼油厂原油加工深度提高，大量采用生产高辛烷值汽油、柴油和液化气重油轻质化工艺，同时考虑到重质与轻质油销售的经济性，减少了向重质油中兑人轻质油，使得供工业炉燃烧用的燃料油基本上就是渣油。早些年使用100＃重油，烧嘴前油加热温度达到60～80 With the technological progress of the petroleum industry, the crude oil processing refinery depth of processing, extensive use of high-octane gasoline, diesel and liquefied petroleum gas light weight of the process, taking into account the sales of heavy and light oil economy, reducing To light oil to heavy people, so that for the combustion of industrial furnace fuel oil is basically the residue. In the early years, 100 # heavy oil was used, and the oil heating temperature before the burner reached 60 ~ 80
