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、爐管爆炸：水質不良引起爐管結垢或腐蝕；缺水和爆管也可能互為因果，此外，由於設計缺陷、材料強度不足和焊接質量不好，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、汽水共騰：產生這種情況的主要原因是：水質不良，含鹽太高或鍋爐負荷增加過急等，發現汽水共騰時，必須加強水質處理和加大連續排汙。

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、鍋爐缺水：發現鍋爐缺水時，應嚴禁進水，並采取緊急停爐措施，造成鍋爐缺水事故的原因大多與運行人員鬆懈麻痹和誤操作有關，或是與水位表因無衝洗措施而發生鍋爐維修堵塞故障有關。

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、鍋爐超壓：司爐人員盲目提高工作壓力或擅離工作崗位造成的；有時，鍋爐維修由於壓力表和閥同時失靈也會引起鍋爐超壓，因此，必須加強對司爐工崗位責任製和附件的檢查。

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.
