我们北裂化装置有两台双斜顶管式加热炉,设计负荷分别为每小时1,600万大卡和每小时800万大卡。共有燃烧喷嘴56套,正常开工生产时,炉子的噪声高达110分贝(A),生产工人长期在这种环境中工作,对身体健康危害很大,而且也影响了生产效率。 为了改变这种状况,提高生产效率,我们于1979 Our North Cracking Unit has two double-beveled tubular furnaces with design loads of 16 million kilocalories per hour and 8 million kilocalories per hour respectively. A total of 56 sets of burning nozzles, the normal start of production, the stove noise up to 110 decibels (A), the production workers long-term work in this environment, a great harm to human health, but also affected the production efficiency. In order to change this situation, improve production efficiency, we in 1979
