In order to ensure the normal and safe operation of the boiler, it is necessary to rely on the close cooperation of the boiler accessories. Although the accessories seem insignificant, they play an important role. In order to ensure the safe and stable operation of the boiler, its staff should be able to respond to the emergencies in the operation process in time. Let's take a look at the long-term events

1、炉管爆炸：水质不良引起炉管结垢或腐蚀；缺水和爆管也可能互为因果，此外，由于设计缺陷、材料强度不足和焊接质量不好，均可能引起爆管事故。

1. Furnace tube explosion: scaling or corrosion of furnace tube caused by poor water quality; Water shortage and pipe explosion may also be mutually causal. In addition, pipe explosion accidents may be caused due to design defects, insufficient material strength and poor welding quality.

2、汽水共腾：产生这种情况的主要原因是：水质不良，含盐太高或锅炉负荷增加过急等，发现汽水共腾时，必须加强水质处理和加大连续排污。

2. Steam water co transpiration: the main reasons for this situation are: poor water quality, too high salt content or too rapid increase of boiler load. When steam water co transpiration is found, water quality treatment must be strengthened and continuous blowdown must be increased.

3、锅炉缺水：发现锅炉缺水时，应严禁进水，并采取紧急停炉措施，造成锅炉缺水事故的原因大多与运行人员松懈麻痹和误操作有关，或是与水位表因无冲洗措施而发生锅炉维修堵塞故障有关。

3. Boiler water shortage: when the boiler is found to be short of water, it is strictly prohibited to enter the water, and emergency shutdown measures shall be taken. The causes of boiler water shortage accidents are mostly related to the operator's laxity, paralysis and misoperation, or the boiler maintenance blockage fault caused by the lack of flushing measures on the water level gauge.

4、锅炉超压：司炉人员盲目提高工作压力或擅离工作岗位造成的；有时，锅炉维修由于压力表和阀同时失灵也会引起锅炉超压，因此，必须加强对司炉工岗位责任制和附件的检查。

4. Boiler overpressure: caused by the stoker blindly increasing the working pressure or leaving the post without permission; Sometimes, due to the failure of pressure gauge and safety valve at the same time, boiler overpressure will also be caused in boiler maintenance. Therefore, it is necessary to strengthen the inspection of Stoker's post responsibility system and safety accessories.
