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.
The biomass energy powder combustion machine of a kind of efficient burning 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; Burner hearth 11 comprises the combustion chamber 111 near crater 14, and the some fire box 112 be communicated with biomass energy powdering inlet 12; Point fire box 112 passes through to be communicated with into burner 15 with combustion chamber 111; The edge entering burner 15 is horn mouth.The entering burner 15 and can utilize Coanda effect (Coanda effect (Coanda Effect) is also known as attached wall effect or Coanda effect of the utility model horn mouth form.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 a fire box 112 when passing through burner 15 and entering combustion chamber 111, to surrounding generation diffusion effect, make biomass energy powder spread and be uniformly distributed rapidly after entering combustion chamber 111, powder can not be produced and assemble situation, be beneficial to biomass energy powder Thorough combustion.
In order to strengthen the diffusion effect into burner 15 pairs of biomass energy powder further, preferably, preferably, the burner 15 that enters of horn mouth form comprises coned face 151 near combustion chamber 111, and is connected to and seamlessly transits cambered surface 152 away from combustion chamber 111 between coned face 151 and some fire box 112.The biomass energy powder flowed out by a fire box 112 along with air-flow along seamlessly transitting cambered surface 152 gradually to external diffusion, and outwards evenly can spread along coned face 151 subsequently.
Preferably, the edge lower part of coned face 151 forms the smooth arc face 1511 being more bent outwardly expansion compared with top.Like this, after air-flow flows out from a fire box 112, have air-flow that small part carries biomass energy powder secretly upwards to spread along the edge upper part of coned face 151, and the air-flow that major part carries biomass energy powder secretly can spread downwards along the edge lower part of coned face 151 through smooth arc face 1511, bottom towards combustion chamber 111 is blown, 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 151, preferably, coned face 151 forms angle with the axis entering burner 15, and the angle of described angle is 7-20 °, specifically can be 7 °, 10 °, 15 ° and 20 °.
The biomass energy powder combustion machine of efficient burning of the present utility model, coned face can carry out adjusting and designing according to actual requirement with the concrete angle of angle of the axis entering burner; 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.
