我厂两台 SZY20—13/250—1燃油锅炉,1974年投产后,每年烧重油1万吨左右。随着我国能源政策的改变,结合我公司二次能源产品结构,一致认为用焦油沥青代替重油在燃油锅炉上试烧是可行的。从1981年3月至1984年3月,通过三年来对供油系统的工艺改造和在操作中取得的一些经验和数据,我们认为用焦 I plant two SZY20-13 / 250-1 oil-fired boiler, put into operation in 1974, the annual burning of heavy oil 10,000 tons. As China’s energy policy changes, combined with our company secondary energy product structure, agreed that the use of tar instead of heavy oil in the trial of burning oil-fired boiler is feasible. From March 1981 to March 1984, through the three years of technological transformation of the oil supply system and some experience gained in the operation and data, we believe that the use of coke
