Abstract
The invention provides an efficient combustion-supporting device for direct combustion furnaces, and relates to a solid-fuel household furnace. A fire retaining cylinder is arranged in a fire hole of a secondary air separation disk of a direct combustion furnace, and an annular fire hole is arranged between the fire retaining cylinder and the secondary air separation disk. The device has the advantages of ensuring sufficient combustion of biomass fuel, greatly improving the thermal efficiency of stoves and reducing the emission of flue gas and other waste gases, along with simple structure, energy conservation, environmental protection and great suitability for biomass direct combustion furnaces.
Description
Technical field
The present invention relates to a kind of solid-fuelled domestic burners, particularly relate to a kind of the direct concentrated combustion of living beings or the stove and accessory of half gasification, and combustion.
Background technology
The biomass energy of China is very abundant, and along with the agricultural and the development of forestry, biomass resource will get more and more, it is current that to utilize the subject matter of biomass energy be that capacity usage ratio is very low, also very unreasonable in the use, cause the huge waste of resource, utilize traditional native kitchen range burning bavin standing grain, stalk as the rural area always, efficiency of combustion is low and labour intensity is big, also damages to environment.
The upright burner of prior biological, be also referred to as half-gasification oven, generally comprise the stove tube and supply biomass combustion once, secondary air-supply device, primary air enters from the bottom or the sidewall of stove tube, the supply of auxiliary air then is arranged on the top of stove tube, middle part at the auxiliary air air distribution disk is provided with fire hole, the fire hole periphery has the auxiliary air venthole, burning is more abundant when making flame pass through fire hole, but because the fire hole of auxiliary air air distribution disk is that open type and aperture are bigger, flame by the time can not mix fully with auxiliary air, especially fire hole middle part burning is insufficient, makes discharged flue gas content height, thermal efficiency of stoves is low, even produce thick smoke, be unfavorable for energy-conserving and environment-protective, make troubles also for user's use.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, can reduce toxic emission such as flue gas, improve the efficient combustion-supporting device of the direct combustion stove of the thermal efficiency.
The present invention is achieved by the following technical solutions.
A kind of efficient combustion-supporting device of direct combustion stove, on stove tube top the auxiliary air air distribution disk is arranged, described auxiliary air air distribution disk is the annular cavity body, outer wall has the auxiliary air air inlet pipe to connect secondary air-supply device, inwall has equally distributed auxiliary air venthole, the middle part is the fire hole of the circle of open type, in the fire hole of the auxiliary air air distribution disk of direct combustion stove firestopping tube is housed, and between firestopping tube and the auxiliary air air distribution disk annular fire hole is arranged.
The present invention can also further realize by following technical measures.
There is the fire-collection ring of taper the fire hole top of described auxiliary air air distribution disk;
Described firestopping tube connects the auxiliary air air distribution disk by leg;
Described firestopping tube is by the affixed fire-collection ring of leg.
It is simple in structure for the efficient combustion-supporting device of a kind of direct combustion stove provided by the invention, in the fire hole of auxiliary air air distribution disk, be provided with firestopping tube, make between firestopping tube and the auxiliary air air distribution disk and form annular fire hole, during burning, flame by annular fire hole and auxiliary air fully, mix uniformly, make sufficient combustion, improved the thermal efficiency of stove and accessory greatly, reduced exhaust gas discharging such as flue gas simultaneously, energy-conserving and environment-protective are highly suitable for biomass direct-fired furnace.
Description of drawings
Fig. 1 is the structural representation of the efficient combustion-supporting device of direct combustion stove;
Fig. 2 is the structural representation of the efficient combustion-supporting device band fire-collection ring of direct combustion stove.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail:
Embodiment one, and the efficient combustion-supporting device of direct combustion stove as shown in Figure 1, holds the stove tube 1 of the circle of biomass solid fuel, its bottom or the porose connection primary air of sidewall feedway, and auxiliary air air distribution disk 2 is arranged at its top; Auxiliary air air distribution disk 2 is the annular cavity body, and outer wall has auxiliary air air inlet pipe 9 to connect secondary air-supply device, and inwall has equally distributed auxiliary air venthole 8, and the middle part is the fire hole 3 of the circle of open type; Firestopping tube 4 is arranged in the fire hole 3, and firestopping tube 4 is open-topped goblet, and sidewall is connected with three legs 6 and connects centring ring, is placed on the upper edge of the fire hole 3 of auxiliary air air distribution disk 2; Form annular fire hole 7 between firestopping tube 4 and the auxiliary air air distribution disk 2.
Biomass solid fuel is in stove tube 1 internal combustion, because can gasifying, the high temperature of stove tube inside forms the part fuel gas, flame and fuel gas are scurried out from fire hole 3, owing to be subjected to the obstruct of firestopping tube 4, flame flow is to annular fire hole 7, the inner chamber that this moment, auxiliary air entered into auxiliary air air distribution disk 2 from auxiliary air air inlet pipe 9 evenly flows to annular fire hole 7 through auxiliary air venthole 8, make that flame and gas fuel burning are more abundant, not only can improve the thermal efficiency greatly, also can reduce exhaust gas discharging such as flue gas, reach energy-efficient purpose, in the biomass fuel combustion process, can not produce peculiar smell, the flue dust of can not kicking up.
Embodiment two, and the efficient combustion-supporting device of direct combustion stove as shown in Figure 2, holds the stove tube 1 of the circle of biomass solid fuel, its bottom or the porose connection primary air of sidewall feedway, and auxiliary air air distribution disk 2 is arranged at its top; Auxiliary air air distribution disk 2 is the annular cavity body, outer wall has auxiliary air air inlet pipe 9 to connect secondary air-supply device, inwall has equally distributed auxiliary air venthole 8, and auxiliary air venthole 8 is holes, shutter shape slit, and the middle part is the fire hole 3 of the circle of open type; The fire-collection ring 5 of taper is placed on fire hole 3 tops and connects auxiliary air air distribution disk 2, and the inboard of fire-collection ring 5 is by three leg 6 affixed firestopping tubes 4, and firestopping tube 4 is open-topped goblet, and firestopping tube 4 is in the fire hole 3 of auxiliary air air distribution disk 2; Form annular fire hole 7 between firestopping tube 4 and the auxiliary air air distribution disk 2.
Biomass solid fuel is in stove tube 1 internal combustion, because can gasifying, the high temperature of stove tube inside forms the part fuel gas, flame and fuel gas are scurried out from fire hole 3, owing to be subjected to the obstruct of firestopping tube 4, flame flow is to annular fire hole 7, the inner chamber that this moment, auxiliary air entered into auxiliary air air distribution disk 2 from auxiliary air air inlet pipe 9 evenly flows to annular fire hole 7 through auxiliary air venthole 8, make that flame and gas fuel burning are more abundant, not only can improve the thermal efficiency greatly, also can reduce exhaust gas discharging such as flue gas, flame shrinks concentrated upwards ejection by the fire-collection ring 5 of taper, and firepower is more concentrated, powerful, further improve the thermal efficiency, reach energy-efficient purpose, in the biomass fuel combustion process, can not produce peculiar smell, the flue dust of can not kicking up, every index is considerably beyond existing standard.
