Recovery Boiler - an overview | ScienceDirect Topics

3/5/2011 · The purpose of the recovery boiler is to recover the inorganic chemicals as smelt (sodium carbonate and sodium sulfide), burn the organic chemicals so they are not discharged from the mill as pollutants, and recover the heat of combustion in the form of steam. The latter is accomplished by large numbers of carbon steel tubes filled with circulating water or steam to recover heat from the walls of the recovery boiler and the flue gases. Fig. 17.10 shows some banks of tubes to be installed into a recovery boiler.

A Boiler: The Explosive Potential of a Bomb

A common cause of explosion is the runaway firing condition that takes place when the boiler's burner does not shut off. In this case, when the hot-water heater is connected to the city water supply on one side and the building hot-water service on the other, the check valve will shut off and no back pressure will go into the city side.

Boiler explosion is a chemical reaction which loses instantly control. The main causes of the explosion accident are as follows. Illegal operation: firstly, before igniting the stove, the operator doesn't clean seriously the hearth or the cleaning time is not enough. When the natural gas in the furnace meets the fire, the boiler will explode. Secondly, the first natural gas valve of entering the hearth is closed loosely. The natural gas leaks in the furnace. Once it meets the fire, the boiler will have the explosion …
