The combustor is characterized in that a cover plate is detachably arranged at the top of the gas mixing chamber, and a plurality of flame holes allowing flame to get out are distributed at intervals on the cover plate. Compared with the prior art, the utility model has the advantages that the cover plate is arranged at the top of the gas mixing chamber and flame holes are formed on the cover plate, so that the cover plate can effectively buffer the pressure of flame ejected from a gas orifice and floating flame is formed on the surface of the cover plate; and the whole combustor has the advantage of low possibility of backfire.
Description
Technical field
The present invention relates to the burner that a kind of gas heater or gas-cooker are used.
Background technology
The burner that existing gas heater or gas-cooker are used, generally comprise the mixing chamber that air is mixed with combustion gas, mixing chamber is provided with combustion gas, the air inlet hole, this air admission hole is corresponding with nozzle, nozzle is injected combustion gas in the mixing chamber, combustion gas is when injecting mixing chamber, also bring air outside into mixing chamber in the lump, in mixing chamber, air fully mixes with combustion gas, top in mixing chamber is provided with fumarole, fumarole is communicated with the mixing chamber inner space, and the fumarole next door generally can be provided with ignition module, after the ignition module igniting, combustion gas in the mixing chamber and AIR MIXTURES penetrate from fumarole under the effect of high pressure, realize igniting.At this moment, after directly the combustion gas of ejection is lighted with air mixture from fumarole, because the high pressure effect generally can form the flame of length.And present burner, its fumarole generally can be provided with a plurality of, when a plurality of fumaroles all after the igniting, can form many combustion flames, if the Position Design of fumarole is improper, can mutual interference mutually between flame and the flame, and tempering phenomenon also appears easily.And outside fumarole is directly exposed to, stopped up by the dust and other impurities in the external world easily.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of burner that can not produce the flame of tempering, generation for floating flame at above-mentioned prior art.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: this burner, comprise the gas mixing chamber that combustion gas is mixed with air, it is characterized in that: the top of described gas mixing chamber detachably is provided with cover plate, and this cover plate is provided with the fire hole that allows flare to pass.
Generally, cover plate can adopt stainless steel to make, and meets condensing drip like this and can not produce cracked under the condition of high temperature.In order to prevent under the condition of high temperature, all the time disperse outwardly from the flame that the cover plate fire hole passes, avoid phase mutual interference between the flame, avoid the stainless steel cover plate under the condition of high temperature, to deform simultaneously, as improvement, the upper surface sidewall side-looking of described cover plate is the arcuate structure to outer lug.The applicant is designed to arcuate structure with the upper surface of this cover plate in long-term experimental study process, can effectively avoid the generation of the problems referred to above, and therefore whole burner is more durable.
Preferably, the side-looking of described cover plate upper surface sidewall is the circular arc type structure, and the arc surface size is good between R360mm～R540mm.Circular arc is too small, does not reach the advantage of above-mentioned cambered surface design, and cambered surface is excessive then can to influence the flame burning direction, causes efficiency of combustion to reduce and the burnt gas increase; The relation of moulding that cambered surface is excessive in addition when involving product and making and fire hole circularity, within this cambered surface size range, fire hole distortion minimum in the time of at utmost guaranteeing formed product.
As improvement, described cover plate snaps onto the top of described gas mixing chamber, and the side of described cover plate is provided with stable flame hole, can make burning fully stable more.
Improve again, described gas mixing chamber comprises mozzle, the premixer, first mixing chamber and second mixing chamber, the air inlet of wherein said mozzle is with corresponding with external nozzles, the gas outlet of described mozzle is communicated with described premixer, described first mixing chamber is arranged on the top of described premixer, and separate by a baffle plate with middle opening, described second mixing chamber is arranged on the top of described first mixing chamber, and separate by a homogenizing plate, be distributed with a plurality of ventholes on this homogenizing plate, described cover plate promptly is arranged on the top of described second mixing chamber.Combustion gas and AIR MIXTURES are through mozzle, after the mixing of premixer, do further mixing through first mixing chamber and second mixing chamber again, can make the more thorough of combustion gas and air mixing, combustion gas simultaneously and air mixture are through after the stopping of above-mentioned homogenizing plate, mixture pressure can obtain certain mitigation, and then further stopping through the second mixing chamber top blind flange, mixture pressure further obtains relaxing, therefore the mixture pressure of going out from cover plate can be less, like this after the igniting, the flame that comes out from the fire hole of cover plate can be the floating flame that relatively relaxes, and can not be a long flare.
Preferably, the diameter of venthole is 1.5～2.5mm on the described homogenizing plate.
The distance of the described homogenizing plate of distance is 9mm～11mm around the described cover plate upper surface, and the distance of the described homogenizing plate of described cover plate upper surface center highest point distance is 11mm～12mm.
Fire hole on the described cover plate comprises circular fire hole and strip fire hole, and adopts circular fire hole between the adjacent strip fire hole at interval.Can avoid phase mutual interference between the flame so better and strengthen the stability of flame combustion.
Compared with prior art, the invention has the advantages that: by the top in gas mixing chamber cover plate is set, fire hole on the cover board is set then, cover plate can effectively cushion the pressure of the flame that shoots out from fumarole, thereby form floating flame, thereby can be so that CO and NO on the surface of cover plate
XDischarge capacity is low, power is big, efficiency of combustion improves; And whole burner has the advantage that is difficult for tempering.Simultaneously cover plate is structurally novel unique, is different from general burner fully, but integral installation, dismounting is very convenient, applicable to the general gas water heater, manifests especially obvious for the water heater advantage of high-power burning.
