Abstract
The utility model provides a kind of simple in structure, preparation and easily extends out formula swirl combustion device, it includes burner hearth, fuel inlet is provided on the combustion chamber partition plate of burner hearth one side, in combustion chamber, the centre of partition plate is provided with air inlet, guide vane is set in the air inlet, and the wind entered through guide vane in burner hearth is formed around burner hearth axis both clockwise or the Whirl deposite tank rotated counterclockwise.The utility model only sets air inlet in combustion chamber partition plate centre, and guide vane is set in air inlet, and the wind entered by guide vane in burner hearth forms Whirl deposite tank（Vortex）.Whirl deposite tank advances when being rotated around burner hearth, is sufficiently mixed with burner hearth fuel, combustion efficiency is more preferably.Since the periphery for entering fire-retardant wind direction burner hearth in burner hearth from center air inlet is spread, formula swirl combustion device is also referred to as extended out.This burner slows down construction, reduces the difficulty of preparation compared with the traditional structure of multiple air inlets for being arranged on burner hearth circumferential direction.
Description
Technical field
The utility model is related to a kind of burner, especially a kind of burner using biomass as fuel.
Background technology
Existing burner, multiple air inlets are arranged in the circumferential direction of burner hearth more, the fire-retardant wind being blown into through air inlet in burner hearth,
Vortex is formed, while around burner hearth axis both clockwise or while rotating counterclockwise moves forward so that the combustion of combustion air and feeding burner hearth
Material fully combines, and burning is abundant.
In order to reach venturi effect, it is necessary to there is multiple air inlets, structure is more complicated, at the same need multiple air ducts with respectively into
Air port is connected, and cost is higher.
The content of the invention
The purpose of this utility model is to provide a kind of simple in structure, preparation and easily extends out formula swirl combustion device.
It is described in the utility model to extend out formula swirl combustion device, including burner hearth, on the combustion chamber partition plate of burner hearth one side
Fuel inlet is provided with, the centre of partition plate is provided with air inlet in combustion chamber, and guide vane, warp are set in the air inlet
The wind that guide vane enters in burner hearth is formed around burner hearth axis both clockwise or the Whirl deposite tank rotated counterclockwise.
Being further improved for formula swirl combustion device is extended out as to above-mentioned, multiple guide vanes are distributed on same circumference
On, the width of the air intake passage between guide vane, in burner hearth in the radial direction from center outwards week gradually increase, in burner hearth
Axial direction on the axis of guide vane and burner hearth into heeling condition.
Being further improved for formula swirl combustion device is extended out as to above-mentioned, igniting is provided with below fuel inlet
Device.
The beneficial effects of the utility model：The utility model only sets air inlet in combustion chamber partition plate centre, into
Guide vane is set in air port, and the wind entered by guide vane in burner hearth forms Whirl deposite tank（Vortex）.Whirl deposite tank side is around burner hearth
It rotates side to advance, be sufficiently mixed with burner hearth fuel, combustion efficiency is more preferably.Due to entering fire-retardant wind in burner hearth from center air inlet
It is spread to the periphery of burner hearth, also referred to as extends out formula swirl combustion device.This burner is arranged on burner hearth week compared with multiple
To air inlet traditional structure, slow down construction, reduce the difficulty of preparation.
Description of the drawings
Fig. 1 is to extend out formula swirl combustion schematic device；
Fig. 2 is the left view of Fig. 1；
Fig. 3 is the air inlet schematic diagram for having guide vane.
In figure, burner hearth 1, combustion chamber partition plate 2, fuel inlet 3, air inlet 4, guide vane 5, air intake passage 6, burner hearth axis
7, igniter 8.
Specific embodiment
Shown in Figure 1 extends out formula swirl combustion device, is set in the centre of the combustion chamber partition plate 2 of 1 one side of burner hearth
Air inlet 4 is equipped with, multiple guide vanes 5 are set in the air inlet.Referring to Fig. 2, multiple guide vanes are distributed on same circumference
On, the width of the air intake passage 6 between guide vane, in burner hearth in the radial direction from center outwards week gradually increase.Referring to
Fig. 3, the axis 7 of guide vane 5 and burner hearth is into heeling condition on the axial direction of burner hearth.Enter from air inlet through guide vane
Wind in burner hearth forms the Whirl deposite tank for rotating around burner hearth axis both clockwise and being moved forward along burner hearth axis.Arrow represents in figure
The wind direction of Whirl deposite tank.
Fuel inlet 3 is provided on combustion chamber partition plate 2, igniter 8 is provided with below fuel inlet.
Operation principle：Fuel is pushed into burner hearth 1 from fuel inlet 3, and fuel is deposited at igniter 8, and igniter lights combustion
Material.Combustion air, into burner hearth, by the guide vane 5 set in air inlet, blows out the wind of rotation, keeps wind direction through air inlet 4
Vorticity can be formed in burner hearth.After fuel combustion, due to the inclination by guide vane, fuel forms vortex in burner hearth
Burning, combustion efficiency are more preferable.
Burner hearth can to keep flat or being placed by certain inclination angle.Can igniting can not also be configured by igniter fire
Device and manually sparking mode.
Claims (3)
1. extending out formula swirl combustion device, including burner hearth, fuel inlet is provided on the combustion chamber partition plate of burner hearth one side, it is special
Sign is：In combustion chamber, the centre of partition plate is provided with blowing mouth, and the blowing mouth sets guide vane, enters through guide vane
Wind in burner hearth is formed around burner hearth axis both clockwise or the Whirl deposite tank rotated counterclockwise.
2. formula swirl combustion device is extended out as described in claim 1, it is characterized in that：Multiple guide vanes are distributed on same circumference
On, the width of the air intake passage between guide vane, in burner hearth in the radial direction from center outwards week gradually increase, in burner hearth
