Description
Technical field
This technology relates to burner, specifically, is a kind of horizontal cyclone biomass burning combustor.
Background technology
Traditional biomass burner, one bottom it flat fixed type grate, what burning adopted is force to wind with air blast from fire grate, this fire grate needs certain space to meet the oxygenating of biomass fuel combustion process, but, biomass fuel always forms coking because not burning cmpletely in combustion, therefore reason coking to be constantly located in, fixed type grate all covers by slagging prevention, otherwise there will be over-emitting black exhaust, if long-time process not in time will cause burner hearth to extinguish.So existing biomass burner Problems existing is: needing to select can not the fuel of coking; the fuel of coking also can not can occur that a large amount of ashes are deposited on fire grate after long-play even select; the effective fuel area of fire grate is caused to diminish; fuel Thorough combustion situation can not become large gradually, needs timing to shut down cleaning fire grate.If select the fuel of coking just cannot use.
Summary of the invention
The object of this technology is to provide one to make full combustion of fuel, prevents fuel coking from piling up, the horizontal cyclone biomass burning combustor of long service life.
For solving the problem, the technical scheme that this technology is taked is:
A kind of horizontal cyclone biomass burning combustor, it comprises Horizontal cylinder shape burner hearth, and one end of burner hearth is closed, and this blind end has the outlet of fuel feed channel; Be provided with feeding packing auger in fuel feed channel, fuel feed channel be provided with the blast orifice for the Way out air blast to fuel feed channel; In hearth wall, have air intake passage, inboard wall of burner hearth arranges tornadotron, tornadotron inner chamber communicates with air intake passage; Tornadotron sets out air holes, and the axis direction of exhaust vent and the radial direction of cylindrical burner hearth form acute angle, make from air intake passage enter tornadotron inner chamber and from exhaust vent out gas in cylindrical burner hearth, form the eddy current rotated in the same direction.
The beneficial effect of this technology: biomass fuel is constantly advanced to the exit of the fuel feed channel in burner hearth by feeding packing auger, after lighting biomass fuel, combust spent fuel above constantly to be pushed away by the Way out of fuel new below toward burner hearth non-close end, thus can continuous operation, even the serious coke-like thing of fuel coking also can be pushed out burner hearth, thus burner hearth can not be accumulated in because of fuel coking and affect particle burning oxygenating, thus ensure hearth combustion effect.
Fuel feed channel is provided with the blast orifice for the Way out air blast to fuel feed channel, the high temperature of burner hearth is blowed to burner hearth by this blast orifice wind out, and flame toward the burning of auger direction, effectively can not prevent tempering.
Air intake passage in burner hearth is not only as air channel effect, more can cool internal protecting wall, thus ensure longer service life.
From the wind out of the exhaust vent tornadotron, at burner hearth according to the air blast of same direction, form spiral combustion mode, thus can better make fuel-pyrolysis gasification, and combustion.
As a further improvement on the present invention, tornadotron is the semi-circular tube that closed at both ends side is opened wide, the axial direction of semi-circular tube and the axis being parallel of cylindrical burner hearth; The open side of semi-circular tube contacts with cylindrical burner hearth; The inboard wall of burner hearth relative with semi-circular tube inner chamber has the hole, furnace wall air intake passage and semi-circular tube inner space.
As a further improvement on the present invention, the cross section of tornadotron is the bending part that two side plates are connected, and the closed at both ends side of this bending part is opened wide, the axial direction of bending part and the axis being parallel of cylindrical burner hearth; The open side of bending part contacts with cylindrical burner hearth; The inboard wall of burner hearth relative with bending part inner chamber has the hole, furnace wall air intake passage and bending part inner space.
Further improve as of the present invention, burner hearth blind end has igniter interface.It is convenient that igniter like this by being arranged on this interface carries out igniting to fuel.

Detailed description of the invention
Be described further below in conjunction with the detailed description of the invention of accompanying drawing to this technology.
Horizontal cyclone biomass burning combustor as Figure 1-3, comprise Horizontal cylinder shape burner hearth 1, one end of burner hearth is closed, and this blind end 2 has the outlet of fuel feed channel 3; Be provided with feeding packing auger 4 in fuel feed channel, fuel feed channel be provided with the blast orifice 5 for the Way out air blast to fuel feed channel; Air intake passage 6 is had in hearth wall.Air intake passage 6 and blast orifice 5 all communicate with the air outlet 9 of air blast.Inboard wall of burner hearth arranges tornadotron 7, and tornadotron inner chamber 71 communicates with air intake passage 6; Tornadotron sets out air holes 72, the axis direction of exhaust vent and the radial direction of cylindrical burner hearth form 30-60 ° of acute angle, make from air intake passage enter tornadotron inner chamber and from exhaust vent out gas in cylindrical burner hearth, form the eddy current rotated in the same direction.Burner hearth blind end 2 has igniter interface 8.In hearth wall periphery, blind end side is provided with flange 10.
See Fig. 2,4, tornadotron is the semi-circular tube that closed at both ends side is opened wide, the axial direction of semi-circular tube and the axis being parallel of cylindrical burner hearth; The open side of semi-circular tube contacts with cylindrical burner hearth; The inboard wall of burner hearth relative with semi-circular tube inner chamber has the hole, furnace wall 11 air intake passage and semi-circular tube inner space.
Certainly, the tornadotron of another structure is see Fig. 5 (with reference to figure 2), and its cross section is the bending part that two side plates 73,74 are connected, and the closed at both ends side of this bending part is opened wide, the axial direction of bending part and the axis being parallel of cylindrical burner hearth; The open side of bending part contacts with cylindrical burner hearth; The inboard wall of burner hearth relative with bending part inner chamber has the hole, furnace wall air intake passage and bending part inner space.
Biomass fuel is forced to advance in burner hearth by auger, before discarded object after burning constantly advanced by fuel below, drop from the outlet 12 of burner, thus burner hearth can not be accumulated in because of fuel coking and affect particle burning oxygenating.
Air divides two tunnels by air blast, and a road enters fuel feed channel, and the high temperature of burner hearth is blowed to burner hearth, and flame can not be burnt toward auger direction.An other transportation work style enters the air intake passage in hearth wall, then enters tornadotron, at burner hearth according to the air blast of same direction, forms spiral combustion mode, thus can better make fuel-pyrolysis gasification, and combustion.
