Detailed description of the invention
In order to explain the technical solution of the utility model further, be described in detail below by specific embodiment.
A kind of new bio mass-energy powder combustion machine of the present utility model, as illustrated in fig. 1 and 2, comprises body of heater 1.
The biomass energy powdering inlet 12, igniter entrance 13 and the crater 14 that are formed with burner hearth 11 in this body of heater 1 and are all connected with burner hearth 11, this biomass energy powdering inlet 12 is disposed adjacent side by side with igniter entrance 13, and this biomass energy powdering inlet 12 and crater 14 are separately positioned on the both sides of burner hearth 11; The edge of biomass energy powdering inlet 12 is horn mouth.The biomass energy powdering inlet 12 of the utility model horn mouth form can utilize Coanda effect, and (Coanda effect (Coanda Effect) is also known as attached wall effect or Coanda effect.Fluid (current or air-flow etc.) has and leaves original flow direction, changes the tendency along with the body surface flowing of protruding into.When there is mantle friction between fluid and its body surface of flowing through (being alternatively fluid viscosity), as long as curvature is little, fluid can flow along body surface.According to Newton's third law, object grants the power of fluid one deflection, then fluid also must grant the power that one, object oppositely deflects.This power embodies clearly in lightweight object, and as soup ladle, but for large aircraft, proportion is not very large.This effect is run after fame with Romanian inventor Henry Condar.), make the air-flow vertically flowed in the pipeline of biomass energy powdering inlet 12 when through biomass energy powdering inlet 12, to surrounding generation diffusion effect, biomass energy powder is made to spread and be uniformly distributed rapidly after entering burner hearth 11, powder can not be produced and assemble situation, be convenient to igniter light a fire to biomass energy powder, and be beneficial to biomass energy powder Thorough combustion.
In order to strengthen the diffusion effect of biomass energy powdering inlet 12 pairs of biomass energy powder further, preferably, the biomass energy powdering inlet 12 of horn mouth form comprises the coned face 121 near burner hearth 11, and seamlessly transits cambered surface 122 away from burner hearth 11 and between the pipeline being connected to coned face 121 and biomass energy powdering inlet 12.The biomass energy powder flowed out by the pipeline of biomass energy powdering inlet 12 along with air-flow along seamlessly transitting cambered surface 122 gradually to external diffusion, and outwards evenly can spread along coned face 121 subsequently.
Preferably, igniter entrance 13 is in the below of biomass energy powdering inlet 12; The edge lower part of coned face 121 forms the smooth arc face 1211 being more bent outwardly expansion compared with top.Like this, after biomass energy powder flows out from the pipeline of biomass energy powdering inlet 12, have small part upwards to spread along the edge upper part of coned face 121, and major part can spread downwards towards igniter entrance 13 along the edge lower part of coned face 121 through smooth arc face 1211, be convenient to biomass energy powder contact with igniter entrance 13 and light a fire, and air-flow blows towards the bottom of burner hearth 11, the powder being deposited on bottom can be blown afloat and burn away, improve the efficiency of combustion of biomass energy powder further.
In order to specific implementation and the diffusion and the effect that ensure coned face 121, preferably, coned face 121 forms angle with the axis of biomass energy powdering inlet 12, and the angle of described angle is 7-20 °, specifically can be 7 °, 10 °, 15 ° and 20 °.
New bio mass-energy powder combustion machine of the present utility model, the concrete angle of the angle of the axis of coned face and biomass energy powdering inlet can carry out adjusting and designing according to actual requirement; The concrete form of smooth arc face and curved expansion degree etc. can be carried out adjusting and designing according to actual requirement; The concrete form of igniter entrance and biomass energy powdering inlet and the position relationship of the two can carry out adjusting and designing according to actual requirement; Coned face can carry out adjusting and designing according to actual requirement with the concrete form seamlessly transitting cambered surface, and say in a broad sense, bell-mouthed form also can carry out adjusting and designing according to actual requirement; Body of heater preferably adopts existing version, but can be cooperation the technical solution of the utility model and do adaptive structural adjustment.
Product form of the present utility model is not limited to this case diagram and embodiment, and anyone carries out suitable change or the modification of similar thinking to it, all should be considered as not departing from patent category of the present utility model.
