Abstract
A pellet fuel swirling-flow combustor comprises a cup-shaped combustor body (1). The upper portion of the combustor body (1) is a trumpet-shaped feeding hopper (2) with a big upper opening and a small lower opening. An annular material gathering swirling-flow groove (3) is arranged on the inner wall of the combustor body (1) under the feeding hopper (2). A plurality of lateral air inlets (4) for air to enter along the tangential direction of a combustor body wall (11) are arranged on the combustor body wall (11) under the material gathering swirling-flow groove (3). A combustor body bottom (5) under the lateral air inlets (4) is an inverted cone with a big top and a small bottom, an igniting bar through hole (6) is arranged at the position of a cone tip, and a plurality of lower air inlets (7) for the air to enter along the same tangential direction of the lateral air inlets (4) are arranged on the periphery of the igniting bar through hole on the combustor body bottom (5). The pellet fuel swirling-flow combustor has good using effect, can enable pellet fuel to be combusted more fully, does not pollute the environment, saves fuel, and enables combustion time of the pellet fuel to be long and the combustion to be full by utilizing blown-in combustion-supporting air along the tangential direction.
Description
Technical field
The utility model relates to burner, is specifically related to a kind of burner that is used for burning particles fuel.
Background technology
Granular fuel is a kind of New-type fuel, and it is to form through the granulator compacting through pulverizing the back with biomass fuels such as stalks.Compare with stalk fuel, it has and does not take up room, the convenient storage and transportation, and more anti-combustion, fuel value is advantages of higher more.The burner that is used for burning particles fuel has also emerged and has obtained popularizing and using, but existing granular fuel combustor result of use is good inadequately, and granular fuel is fully burnt, and has not only wasted fuel but also contaminated environment, needs further to improve.
Summary of the invention
The purpose of the utility model provide a kind of result of use good, can make granular fuel burning more fully, the not only granular fuel turbulent burner of free from environmental pollution but also fuel saving.
The technical solution of the utility model is: it comprises cup-shaped burner device body; The top of device body is big young tubaeform feed hopper down suitable for reading; The device body inwall of feed hopper below is provided with annular and holds together to expect the eddy flow groove; The device body wall that holds together to expect eddy flow groove below is provided with along several side air inlets of device body wall tangential direction air intake; At the bottom of the device body of side air inlet below is up big and down small back taper, and the awl point position at the bottom of the device body is provided with the fire rod through hole, at the bottom of the device body on the periphery of fire rod through hole be provided with several and side air inlet following air inlet along the same tangential direction air intake.
The technique effect of the utility model is: its result of use is good, can make granular fuel burning more abundant, not only free from environmental pollution but also fuel saving.It utilizes the combustion air that tangentially is blown into to make granular fuel longer burning time, and it is more abundant to burn, and burn-off rate can reach more than 98%; The flue dust that is produced still less, the heating stroke of flame is longer, discharges heat energy to greatest extent; More help energy-conserving and environment-protective; It is easy for operation, and cost simple in structure is low, is more convenient for using.
Description of drawings
Fig. 1 cuts open figure for the three-dimensional office of the upright shape of the utility model embodiment;
Fig. 2 is the utility model embodiment back-off shape stereogram.
The specific embodiment
Like Fig. 1, shown in Figure 2; It comprises cup-shaped burner device body 1; The top of device body 1 is big young tubaeform feed hopper 2 down suitable for reading; Device body 1 inwall of feed hopper 2 belows is provided with annular and holds together to expect eddy flow groove 3, holds together to expect that the device body wall 11 of eddy flow groove 3 belows is provided with along several side air inlets 4 of device body wall 11 tangential direction air intakes, and 5 is up big and down small back taper at the bottom of the device body of side air inlet 4 belows; 5 awl point position is provided with fire rod through hole 6 at the bottom of the device body, at the bottom of the device body on 5 the periphery of fire rod through hole be provided with several and side air inlet 4 following air inlet 7 along the same tangential direction air intake.
Feed hopper 2 is a big young spherical surface body down suitable for reading.Hold together to expect that eddy flow groove 3 is surrounded by ring ladder groove 12 and the feed hopper 2 of being located on device body 1 inwall, the top links to each other with the lower wall of feed hopper 2.Side air inlet 4 along the direction of device body wall 11 tangent line air intakes for overlooking clockwise direction.The device body wall 11 of side air inlet 4 positions is welded on respectively by the middle part of some bottom and upper segments on the device body wall 11 of its above and below, along equidirectional circumferentially the arc-like sheet 8 that laminates mutually in order of head and the tail constitute, the slit that each arc-like sheet 8 head and the tail laminates the position mutually constitutes the side air inlet 4 of air intake tangentially.Fire rod through hole 6 is along device body 1 bar hole radially, and fire rod can the interior granular fuel of axial horizontal igniter body.Following air inlet 7 along the direction of device body 1 tangent line air intake for overlooking clockwise direction.Following air inlet 7 by be provided with some at the bottom of the device body 5 tops swept away and constituted along the punching 9 formed punchings of identical circumferential perk.
Tubaeform feed hopper 2 is convenient to the top charging.Combustion air prolongs the tangential direction of device body 1 from side air inlet 4 and following air inlet 7 insufflator bodies 1; Hold together to expect that eddy flow groove 3 can make the granular fuel that is blown afloat by combustion air in holding together to expect eddy flow groove 3, rotate and burns; And can directly do not blown out device body 1; Increased the time and the stroke of granular fuel burning, and be fully burned, constantly had granular fuel to drop in the process of burning from the top of feed hopper 2; And blown afloat by combustion air and to be rotated burning, the granular fuel of sufficient combustion can become light ash and taken out of from the end opening of feed hopper 2 by flame.Granular fuel is lighted through the electrical heating fire rod.
