The utility model content
The purpose of this utility model is to provide a kind of efficient biomass fuel-fired furnace, and it is simple in structure, and combustion efficiency is good.
For achieving the above object, the utility model adopts following scheme: the efficient biomass fuel-fired furnace, the bottom of furnace shell has air inlet, the upper fixed that is positioned at air inlet in furnace shell has fire grate, the combustion chamber of having taken a seat on the fire grate, the space that has between combustion chamber and furnace shell communicates with air inlet, the feed pipe that is connected on the combustion chamber stretches out furnace shell, the upper end of furnace shell is connected with table, the table upper end has fire door, sidepiece has exhaust opening, and the place, top that is positioned at combustion chamber in the table is provided with a burner, and the cross section of the cavity of burner reduces from the bottom to top gradually, and the cavity of burner is with a firestopping ring facing to combustion chamber in the outside of burner.
By such scheme as seen, the efficient biomass fuel-fired furnace that the utility model provides in use, the wind that is entered by air inlet can enter into combustion chamber first, to realizing air feed in it, and also can be by the air feed in burner of the space between combustion chamber and furnace shell, in the combustion chamber burned flame and imperfect combustion flue gas and converge in burner by the wind that the space between combustion chamber and furnace shell enters after, can in burner, further fully burn, and then can improve combustion efficiency, and the formation of minimizing flue dust, in addition, because the cross section of the cavity of burner reduces from the bottom to top gradually, the duration and degree of heating of the flame of discharging from the burner upper port is more concentrated.
The utility model is simple and reasonable for structure, and it can realize burning more fully to biomass fuel, and the flue dust that is produced is little, is a kind of desirable energy-conservation, efficient biomass fuel-fired furnace.
