Abstract
The utility model relates to a partially pre-mixing type gas combustor to reduce the produced harmful substances when the gas is burning. The utility model provides a low pollution gas burner which comprises an air cylinder, a gas pipe, a mixing chamber, a flame stabilizing plate and a flame diffusing port. The utility model is characterized in that the air cylinder is provided with two symmetric long slots to make the flame diffusing port to move along the long slots, thereby changing the ventilation area, and preventing the occurrence of incomplete combustion, a front plate of the mixing chamber is provided with a gas hole and an air hole which are alternately arranged, so that the mixing of gas and air is improved, the flame stabilizing plate is provided with small holes which are arranged in a rhombus to prevent the occurrence of flame lifting and tempering. The combustor provides a simple structure, improves the stabilization of gas burning, reduces the pollution and improves the air environment.
Description
Technical field the utility model relates to burner, belongs to part especially and gives mixing burner.
Background technology
Gas burner is widely used on the industries such as boiler, combustion apparatus, industrial heating furnace, incinerator, ironing equipment.Existing gas burner has and gives mixing, part fully and give three types of mixing, diffusion types, and it is better that part is given mixing combustion stability comparatively speaking.But burner all exists usually and takes off fire, tempering phenomenon, and especially during fuel gas buring, the flue gas of generation is directly emitted by chimney, except carbon dioxide, steam, also has harmful substances such as carbon monoxide, nitrogen oxide in the flue gas.Carbon monoxide is that the imperfect combustion of combustion gas causes, and producing unburnt reason roughly has: combustion gas mixes inhomogeneously with air, and flame is oversize, touches water-cooling wall, and the burning required air is under-supply etc.Mainly contain two conditions and nitrogen oxide generates: the one, flame temperature height, the 2nd, combustion zone oxygen content height.These harmful substance pollutant atmospheres bring serious harm to health.
Summary of the invention
The purpose of this utility model is the deficiency at above-mentioned existence, and a kind of low pollution gas burner is provided, and the pollution that it produces in the time of can reducing fuel gas buring effectively improves air ambient.
The utility model is to realize by following technical scheme, it comprises air collector, combustion tube, mixing chamber, steady flame plate, flame spread mouth, its structural feature is two elongated slots that air collector is provided with symmetry, two set screw are passed an elongated slot respectively and are connected with the arc plate that the flame spread mouth is provided with, on mixing chamber header board circumferential plane, be provided with airport and the fuel gas hole alternately arranged, be provided with little air hose in the airport, on steady flame plate circumferential plane, be provided with intensive aperture.
Do three places on the utility model structure and improved, be provided with the air collector elongated slot, the flame spread mouth is moved, changed ventilation area, restrained the generation of nitrogen oxide in the flue gas.On the mixing chamber header board, be provided with and alternately arrange airport and fuel gas hole, improved combustion gas and air and mixed, avoided the generation of carbon monoxide.On steady flame plate, be provided with aperture, taking off fire and tempering phenomenon with what prevent flame.This burner structure is simple, has improved combustion stability, has reduced pollution.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a structure A-A profile of the present utility model.
Fig. 3 is that structure B of the present utility model is to steady flame board plane figure.
Embodiment
The utility model is described in further detail below with reference to embodiment shown in the drawings.
Among Fig. 1, this gas burner comprises an air collector 1, be air duct, in the tube Gas Pipe 2 is arranged, it is blast tube, it links to each other with the mixing chamber 3 of head, fuel gas hole 6 and little air hose 4 are arranged on the header board 5 of mixing chamber 3, combustion gas enters mixing chamber 3 from Gas Pipe 2 through fuel gas hole 6, air enters the back by air collector 1 and divides two parts, and portion of air (primary air) enters mixing chamber 3 through little air hose 4, when burner operation, after combustion gas, primary air mix in head mixing chamber 3, aperture 8 ejection burnings from the steady flame plate 7.Be processed with two elongated slots 11 of symmetry on the air collector 1, flame spread mouth 9 lower ends are welded with two symmetrical arc plates 10, and set screw 12 is passed elongated slot 11 and is connected with arc plate 10, and the flame spread mouth is moved up and down along the elongated slot direction.During burner operation, another part air (auxiliary air) enters burner hearth by the passage between head mixing chamber 3 and the flame spread mouth 9, and does not burn combustion gas and carries out diffusion combustion.By movable flame diffusing opening 9 on elongated slot, adjust the relative position between flame spread mouth 9 and the mixing chamber 3, can change the circulation area of auxiliary air, concerning burner, primary air circulation area is fixed, and therefore changes auxiliary air circulation area, just can change the assignment of traffic ratio that comprises primary air, thereby the air mass flow in the assurance mixing chamber forms part and gives mixing burning at the 40-70% of burning required air.Changed the ratio of primary air flow, can reach the purpose of the control length of flame, in certain zone, finished, avoided touching cold surface and produce unburnt phenomenon because of flame is oversize thereby guarantee to burn.Guaranteed also simultaneously that gas concentration does not promptly have excessive oxygen to exist greater than the burning concentration under the combustion stoichiometry ratio in the combustion zone in the combustion zone of maximum temperature, can not produce a large amount of nitrogen oxide.
Among Fig. 2, be drilled with fuel gas hole 6 and the airport alternately arranged on the header board 5 of mixing chamber 3, little air hose 4 is housed in the airport, by alternately the combustion gas and the air of aligned apertures mix (as Fig. 1) fast, fully in mixing chamber, with the inhomogeneous caused flame instability of elimination local concentration, thus the generation of carbon monoxide in the supression flue gas.
Among Fig. 3, be drilled with the intensive aperture 8 of diamond array on steady flame plate 7 circumferential plane, combustion gas and air mixture from steady flame plate 7 ejections, the igniting back produces the flame of certain-length, owing on the steady flame plate aperture that assumes diamond in shape and arrange is arranged, during burner operation, little fire on the aperture pins down mutually, promptly the root of other little fire on the steady flame plate of burner is lighted a fire, guaranteed that flame does not take off fiery phenomenon, the metallic walls of while because of the small fire hole of steady flame plate has the effect that reduces flame propagation velocity, also tempering phenomenon can not take place, and improved the stability of burner combustion.
