针对一起燃油工业锅炉缺水干烧事故,通过对现场发现的问题进行分析,发生事故的主要原因为:给水泵轴承机械故障卡死,低水位连锁保护动作无法进水;传感型水位计选用和安装位置错误,极低水位电极棒结垢失灵;未安装极低水位遮断器;司炉工长时间脱岗。结合实际应用和工作经验,提出了防止类似事故的建议和相关措施,对锅炉安全运行具有实际意义。 Aiming at the accidental dry-burning of oil-fired industrial boilers, the main reasons for the accidents were as follows: the mechanical failure of the pump bearings was blocked, and the low-water-level chain protection could not feed water; the sensor-type water level meter used And the installation location is wrong, very low level electrode rod scaling failure; not installed very low water level breaker; fireman long off Gang. Combined with practical application and work experience, the suggestion of preventing similar accidents and related measures are put forward, which have practical significance to the safe operation of boilers.
