State the fire grate that burner hearth bottom is annular；Described circular air inlet pipe is located at described lower cone gallbladder lower end, fixes at described lower cone gallbladder inwall
Multiple vertical secondary air channel, described secondary air channel is had to be connected with described circular air inlet pipe；Described secondary air channel is provided with out
Air holes.
Improving further as this utility model, described epicone gallbladder bottom is the most in tapered shape.
Improving further as this utility model, described lower cone gallbladder top is from top to bottom in diverging shape.
Improving further as this utility model, described secondary air channel is three.
Improving further as this utility model, the cross section of described secondary air channel is half-circle-arc shape, and upper end is envelope
Mouthful；Described secondary air channel has multiple exhaust vent along described lower cone gallbladder tangential direction, and its direction is consistent.
Improve further as this utility model, described circular air inlet pipe has a main air inlet and three air-out
Mouthful；Described main air inlet is connected with external secondary aerator, and three air outlets are evenly distributed on the circle of described circular air inlet pipe
Secondary air channel lower end connection described in Zhou Shangyu.
Improving further as this utility model, described fire grate overarches, and uniformly processes multiple air intakes on described fire grate
Hole.
Improving further as this utility model, be provided with blower fan outside described burner hearth, the blast pipe of described blower fan is arranged on
Below described fire grate, wind is from bottom to top.
The beneficial effects of the utility model are: by the X-type cone gallbladder by epicone gallbladder with lower cone gallbladder composition, by boring the contracting of gallbladder
Neck effectiveness, extends flue gas time of staying in burner hearth, along lower cone gallbladder wall tangential direction high speed rotating secondary wind resting on down
Flue gas strong disturbance at cone gallbladder is got up, and allows the fuel gas in flue gas fully mix mutually with air, and fuel gas is in burner hearth
Fully burning, decreases boiler gas incomplete combustion loss, improves boiler efficiency, has saved energy resource consumption, stopped boiler
Over-emitting black exhaust phenomenon, improves environmental requirement.
Accompanying drawing explanation
Fig. 1 is the sectional view of this utility model a kind of small-sized biomass boiler furnace structure；
Fig. 2 be Fig. 1 A-A to cross sectional plan view.
In figure: 1, epicone gallbladder；2, lower cone gallbladder；3, circular air inlet pipe；4, secondary air channel；5, fire grate.
Detailed description of the invention
As it is shown in figure 1, a kind of small-sized biomass boiler furnace structure of this utility model embodiment, including: epicone gallbladder 1,
Lower cone gallbladder 2, circular air inlet pipe 3, secondary air channel 4 and fire grate 5；Wherein, epicone gallbladder 1 lower end is welded with lower cone gallbladder 2 upper end, the two
It is internally formed the burner hearth of a connection, at the fire grate 5 that burner hearth bottom is annular.Circular air inlet pipe 3 is located at lower cone gallbladder 2 lower end,
Lower cone gallbladder 2 inwall is fixed with multiple vertical secondary air channel 4, and secondary air channel 4 is connected with circular air inlet pipe 3；On secondary air channel 4
It is provided with exhaust vent.Fire grate 5 overarches, and uniformly processes multiple fresh air inlets, be provided with blower fan, entering of blower fan outside burner hearth on fire grate 5
Airduct is arranged on below fire grate 5, and wind is from bottom to top.Epicone gallbladder 1 bottom is the most in tapered shape, and lower cone gallbladder 2 top is certainly
Upper and under in diverging shape.
As in figure 2 it is shown, secondary air channel 4 is three, the cross section of secondary air channel 4 is half-circle-arc shape, and upper end is sealing；
Secondary air channel 4 has multiple exhaust vent along lower cone gallbladder 2 tangential direction, and its direction is consistent.Have a master on circular air inlet pipe 3 to enter
Air port and three air outlets；Main air inlet is connected with external secondary aerator, and three air outlets are evenly distributed on circular air inlet
Connect with secondary air channel 4 lower end on the circumference of pipe 3.
Time specifically used: wind is sent into circular air inlet pipe by main air inlet by overfire air fan, then enters two through air outlet
