Circulating Fluid Bed (CFB) boiler, which is developed in recent years, is one kind of energy saving and environmental protection industrial boiler.The high temperature corrosion of CFB boiler will lead to the safety accidents of water wall tube and shorten the service life of the boiler,causing huge economic losses,therefore,we should have a good knowledge of how to prevent that.

When the circulating fluidized bed boiler is in intense burning,a negative pressure shrinkage ring forms in the high temperature flame area,the cross-impact of a large number of primary and secondary air exists,the more intense the burning,the more serious the impact.According to this phenomenon,controlling the combustion center away from the high temperature radiation serious area such as back-arch water wall can effectively prevent the high temperature corrosion phenomena of burning center.

Reduce the flame center of circulating fluidized bed boiler,establish the efficient combustion under the front and rear arch.Narrow the furnace radiation area,increase the flue gas convective area.Improve the fire fullness degree in the grate,creating a temperature field of rapid attenuation in the furnace,to prevent fire rush to the wall wall directly,make the front and rear arch area temperature lower than the ash melting point.

Circulating fluidized bed boiler combustion adjustment: only the burning structure is reasonable,the furnace temperature field attenuation is appropriate,the amount of smoke carrying ash can be reduced, which can slow down the high concentration gather of floating objects on tube wall,and can effectively reduce the the erosion of chlorine sulfur compounds on the tube wall.

In order to reduce the high temperature corrosion,ZG energy-saving circulating fluidized bed boiler adopts the unique anti-wear bell jar type hood,which ensures the boiler combustion efficiency.Pleasure feel free to contact us for more details!
