危险性分析1.由于司炉工误操作,水位计或自动给水装置失灵,以及省煤器渗漏大量跑水或排污阀关闭不严、止回阀故障等原因造成缺水。严重缺水可导致受热面过热烧毁,降低受热面钢材的承载能力.金相发生劣化,炉管爆破,甚至造成锅炉爆炸。2.司炉工失职、水位计故障、自动上水失灵会造成满水。蒸汽大量带水会降低蒸汽品质甚至发生水击,损坏管道,破坏用汽设备。3.水质不符合要求,锅炉水含盐量
Risk Analysis 1. Due to misuse of the fireman, water level gauge or automatic water supply device failure, as well as a large number of run-up water economizer or drain valve closed lax, check valve failure and other causes of water shortage. Severe water shortage can lead to overheating of the heated surface, reducing the bearing capacity of the heated steel surface, deteriorating the metallographic phase, blasting the furnace tube and even causing the boiler to explode. 2. Stovework dereliction of duty, water level gauge failure, failure will automatically result in water full of water. A large amount of steam will reduce the quality of steam water or water hammer, damage to the pipeline, destruction of steam equipment. 3. The water quality does not meet the requirements, the boiler water salinity
