1990年3月10日,我市某厂一台SZF6.5-13型锅炉发生严重缺水事故。锅炉本体受到严重损坏,被迫停炉大修,造成很大经济损失。 1 事故经过 3月10日晚9点40分,当班司炉工发现锅炉引风机电流下降,查找原因,发现铸铁省煤器底部有水漏出,即认为省煤器损坏,打开旁通烟道继续运行。此时水位计已见不到水位,便让徒工用旁路给水管向锅炉上水,仍不见水位,且锅炉内有异常声音,这时司炉工立即关闭给水阀,采取紧急停炉措施。 2 事故后现场检查情况从炉膛内部检查发现,炉膛四周水冷壁管普遍发生严重弯曲变形,最大变形量约400mm,水冷壁顶棚 March 10, 1990, a factory in our city a SZF6.5-13 type boiler serious water shortage accident. The boiler body was severely damaged and was forced to shut down for overhauling and caused great economic losses. 1 accident after 9:40 on the evening of March 10, the shift fireman found boiler induced draft fan current drop, find the reason and found that the bottom of cast iron economizer water leakage, that economizer damage, open the bypass flue to continue to run . At this time the water level gauge has not seen the water level, so apprentice bypass pipe to the boiler water, still not see the water level, and the boiler has an abnormal sound, then the fireman immediately close the water valve to take emergency shutdown measures. 2 scene after the accident check the situation found from the internal inspection of the furnace found that the furnace around the water wall pipe generally serious bending deformation, the maximum deformation of about 400mm, water wall ceiling
