Abstract
The invention discloses a forward and reverse air distribution structure for a biomass burner, which comprises a panel, secondary forward air distribution holes, secondary reverse air distribution holes, a burning chamber, a feed shaft, primary air distribution and a bellows, wherein the feed shaft is arranged in the middle of the interior of the burning chamber; and an upper layer of air distribution holes and a lower layer of air distribution holes are uniformly formed in the upper side wall of the periphery of the burning chamber, i.e., a layer of secondary forward air distribution holes and a layer of secondary reverse air distribution holes. A bypass of the secondary forward air distribution holes forms a drift angle with the section of the burning chamber; the drift angle of the bypass of air distribution holes in the same layer leans in the same direction; the drift angle of the bypass of the secondary reverse air distribution holes leans in the direction opposite to the leaning direction of the drift angle of the bypass of the secondary forward power distribution holes; the air in the bellows enters the burning chamber from the secondary forward air distribution holes to flow in circulation so as to form the circulation of air distribution of the upper layer or enters the burning chamber from the secondary reverse power distribution holes to flow cyclically to form the circulation of air distribution of the lower layer; and the circulation of air distribution of the lower layer is reverse to the direction of air distribution of the upper layer. The forward and reverse air distribution structure for a biomass burner has the advantages of sufficient combustion, reasonable air distribution and increased thermal utilization rate of fuel.
Description
Technical field
The present invention relates to a kind of biomass burner air distribution structure, particularly relate to the positive and negative air distribution structure of a kind of biomass burner.
Background technology
At present; The air distribution major part of biomass burner is air distribution from bottom to top, secondary direct projection air distribution from the inside to surface, but the oxygen in the combustion chamber is because the lot of consumption of burning still exists air distribution not enough; Flammable volatile combustion is insufficient; Problems such as be prone to cause the air distribution dead angle, air distribution is unreasonable, and fuel availability is lower.
Summary of the invention
Problems such as the present invention is exactly the problem that exists to the said goods, provides a kind of biomass burner positive and negative air distribution structure, and the flammable volatile combustion that solves the said goods existence is insufficient, causes the air distribution dead angle easily, and air distribution is unreasonable.
The present invention adopts following technical scheme: the positive and negative air distribution structure of a kind of biomass burner; Comprise panel (1), the positive wind distributing hole of secondary (2), the anti-wind distributing hole of secondary (3), combustion chamber (4), feed shaft (5), an air distribution (6), bellows (7); The middle part is provided with feed shaft (5) in the combustion chamber (4); Combustion chamber (4) periphery upper side wall is evenly laid upper and lower two-layer wind distributing hole; Be respectively the positive wind distributing hole of secondary (2) layer, the anti-wind distributing hole of secondary (3) layer, the tangent plane of the positive wind distributing hole of secondary (2) by-path and combustion chamber (4) forms the drift angle, and the drift angle of the wind distributing hole by-path of layer deflection is identical together; The drift angle deflection of the anti-wind distributing hole of secondary (3) by-path is opposite with the drift angle deflection of the positive air distribution of secondary (2) hole by-path; The positive wind distributing hole of secondary (2), the anti-wind distributing hole of secondary (3) be shaped as circle, ellipse, square, rectangle any one, the shape of combustion chamber (4) can for circular, oval, square, rectangle any one, the material of combustion chamber (4) is any one of stainless steel, iron, cast iron and refractory material; Biomass fuel is got in the combustion chamber (4) by feed shaft (5) and burns; Carry out an air distribution (6) by feed shaft (5) below, the wind in the bellows (7) gets in the combustion chamber (4) from the positive wind distributing hole of secondary (2) and circulates simultaneously, forms upper strata air distribution circulation; In the anti-wind distributing hole of secondary (3) entering combustion chamber (4), circulate, form the lower floor air distribution circulation opposite with upper strata air distribution wind direction.
The present invention compared with prior art has following beneficial effect: the positive and negative air distribution structure of said a kind of biomass burner can make flammable volatile combustion abundant, does not cause the air distribution dead angle, and air distribution is reasonable, improves fuel heat utilization.
