废热锅炉是乙烯裂解炉上重要的冷换设备,在高温高压下工作,其作用是冷却高温裂解气,并产生高压蒸汽。废热锅炉一旦出现事故,不仅对裂解炉,而且对整个乙烯装置的生产,都带来极大的影响,会造成严重的经济损失,所以,凡属废热锅炉的事故,必须给予认真探讨,并彻底解决。 Waste heat boiler ethylene cracking furnace is an important cold exchange equipment, work under high temperature and pressure, its role is to cool the pyrolysis gas, and produce high-pressure steam. In the event of an accident, the waste heat boiler will have a tremendous impact not only on the cracking furnace but also on the production of the entire ethylene plant, resulting in serious economic losses. Therefore, all accidents involving waste heat boilers must be carefully explored and completely eliminated solve.
