Steam boiler is the main boiler for commercial water, community water, but the main cause of gas boiler accidents is because of the flue explosive gas and has reached the limit of the explosion, and then and the high temperature in the boiler meets the furnace chamber explosion. Generally occur in such a situation are mostly in

Boiler ignition operation errors caused by the time, but also may be caused by automatic control failure.

In the process of boiler operation, because the wind pressure fluctuations in the burner is too large and caused the backfire, in order to reduce the explosion for the destruction of the gas mixture in the flue, the boiler should be equipped with explosion-proof door, when a gas explosion occurs, the explosion-proof door will be due to the increase in the pressure in the flue and open, which will reduce the damage caused by the explosion of the extent of the boiler at this time.

The extent of the boiler needs to be exposed to protect this time, you can also use water spray to carry out the role of cooling
