Guide: What are the common failures of the boiler and how to repair the failures? 1. The boiler lacks water. Severe water shortage in the boiler will cause deformation and damage to the pressure components and explosion of the furnace tube. If it is not handled properly, a boiler explosion may occur. When the boiler is found to be short of water, it is strictly forbidden to enter the boiler, and emergency shutdown measures shall be taken. The causes of boiler water shortage accidents are mostly related to the lax paralysis and misoperation of the operators, or to the blockage of the water level meter due to no flushing measures.

  1. The boiler lacks water. Severe water shortage in the boiler will cause deformation and damage to the pressure components and explosion of the furnace tube. If it is not handled properly, a boiler explosion may occur. When the boiler is found to be short of water, it is strictly forbidden to enter the boiler, and emergency shutdown measures shall be taken. The causes of boiler water shortage accidents are mostly related to the lax paralysis and misoperation of the operators, or to the blockage of the water level meter due to no flushing measures.

  2, soda and drink together. The characteristics of the co-booming of soda and water: the water level of the water level gauge fluctuates violently, the pot water is foamed, a large amount of water is contained in the steam, the temperature of the steam drops, and water shock occurs in the pipeline when it is severe. The main reasons for this situation are: poor water quality, too high salt content or excessive increase in boiler load. When it is found that soda and water are co-producing, it is necessary to strengthen water treatment and increase continuous sewage discharge.

  3. Boiler overpressure. Boiler over-pressure operation may cause component deformation and damage to the joints: in severe cases, it may cause an explosion. The main reason for the occurrence of boiler overpressure is that the boiler fireman blindly increases the working pressure or leaves the job without authorization. Sometimes, due to the failure of both the pressure gauge and the safety valve at the same time, the boiler will be overpressured. Therefore, it is necessary to strengthen the inspection of the responsibility system and safety accessories of the furnace worker.

  4. The furnace tube exploded. When the furnace tube exploded, there was a noticeable blasting sound and steam jet sound, and at the same time, the water level and vapor pressure dropped. When this situation is discovered, emergency shutdown measures must be taken. The general reasons for this situation are: poor water quality causes the furnace tube to scale or corrode; water shortage and tube burst may also cause each other. In addition, due to design flaws, insufficient material strength and poor welding quality, pipe burst accidents may be caused.
