Common household fire tube boiler accident reconstruction of the boiler parse (a) in the transformation process in the boiler for the original boiler will run this or that accident boilers, boiler explosion is one of them. Under normal circumstances, if the boiler during operation, the emergence of pipes get clogged, incomplete combustion boiler fuel remaining in the boiler, the boiler water and other accidents, without timely treatment is very likely to cause explosion of boilers. In addition, during boiler operation, if the boiler feed water quality is not up to appear, boiler scaling severe corrosion, and very prone to boiler explosion. Another point is that during boiler operation, if the boiler is running a long long time, boiler components aging, inadequate internal systems contribute, in time for the renovation, and very easy to boiler explosion occurs. Therefore, for these phenomena, poor operating results in the boiler, higher operating costs and greater security risk when, as far as possible the original boiler or boiler demolition of the original new process to ensure that in a safe, stable and efficient operation of the boiler state, creating higher benefits for life and production.

Hot water household fire tube boiler in the school dormitory and classroom building are generally used for central heating, drinking water and bathing water aspects of teachers and students and so on.

The reason industrial household fire tube boiler explosion and the cause of industrial boiler explosion hazards and hazards? For chemical plant before use, it must be to raise awareness of prevention. So as to avoid unnecessary losses to yourself. During boiler operation, the pressure exceeds a predetermined pressure to certain parts of elements, the thin portion will suddenly break, crack out immediately stored in the pot will be full of steam. In an instant, a pressure drop equal to pot the external atmosphere. At this time, since the momentum intense, so that part of violent boiling pot filled with water, the expansion, a small part of the whole pot steam also will be warmed, a pressure rises again, further expansion gap. Because full of water and steam in the rapid expansion of one-tenth to twenty second, when gunpowder exploded just as the rapid expansion of the gas, they become a powerful shock wave, with great destructive power. When the boiler explosion, due to the bursting of steam and water has a very high speed, or when the front portion in contact with air, will have a huge reaction, or moves off the boiler in the direction of the reaction force, rolling. Vertical boiler mainly in the blast site and calf ring potshell welding, explosion, steam, the water jet, and then pushed up Boiler fly. Horizontal boiler explosion member burners or more in the weld of the tube plate and the drum, the drum in contact with the combustion. When the explosion occurred, steam and water splashing forward or backward or downward, parallel to the fly boiler, boiler and rolling at the scene. A boiler explosion released energy is only a small fraction of the steel sheet to tear the boiler, in addition to steam and debris and the pipes, valves and the valve body is connected to the boiler, the energy transfer most of the other great shock wave in air, causing a large number of peripherals, badly damaged buildings, as well as the formation of casualties.

In any case, household fire tube boiler safety is one of the concerns of customers all over the world. The products of ZG boiler are not only sold to the world, but also widely praised.
