本沸腾炉的蒸发量:20t/h,汽压:2、45MPa,汽温:400℃,担负着热电联产1500KW汽轮发电机压差发电,背压真空制盐的双重任务,一年盐产量五万吨,自1993年1月安装峻工投产至1994年8月28日,实际只运行了15个月,就发生七次埋管磨穿漏水停炉事故。经有关工程技术人员进炉膛仔细观察,发现大都发生在煤流入口的B点区距风帽群900mm处,(见图1)。 The boiling furnace evaporation: 20t / h, steam pressure: 2,45 MPa, steam temperature: 400 ℃, responsible for the cogeneration 1500KW turbo-generator differential pressure power generation, back-pressure vacuum salt dual task, a year of salt production 50,000 tons, since January 1993, the installation of the completion of the commissioning to August 28, 1994, the actual operation of only 15 months, occurred seven times buried pipe mill wear leakage shutdown. After careful observation of the engineers and technicians into the furnace, it was found that most of them occurred at 900mm at the B point of the inlet of the coal stream (Figure 1).
