Description

A kind of burner

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 comprises the mixing chamber that air is mixed with combustion gas, and mixing chamber is provided with combustion gas, air inlet hole; This air admission hole is corresponding with nozzle, and nozzle is injected combustion gas in the mixing chamber, and 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 above-mentioned prior art a kind of burner that can not produce the flame of tempering, generation for floating flame to be provided.

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 said 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 under the condition of high temperature, meets condensing drip like this and can not produce cracked.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 said 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 said 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, said cover plate snaps onto the top of said gas mixing chamber, and the side of said cover plate is provided with stable flame hole, can make burning fully stable more.

Improve again; Said gas mixing chamber comprises mozzle, 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 said mozzle is communicated with said premixer, and said first mixing chamber is arranged on the top of said premixer and separates through a baffle plate with middle opening, and said second mixing chamber is arranged on the top of said first mixing chamber and separates through a homogenizing plate; Be distributed with a plurality of ventholes on this homogenizing plate, said cover plate promptly is arranged on the top of said second mixing chamber.Combustion gas and AIR MIXTURES are done further mixing through first mixing chamber and second mixing chamber again through after the mixing of mozzle, premixer, and can make the more thorough of combustion gas and air mixing; Combustion gas simultaneously and air mixture are after passing through the stopping of above-mentioned homogenizing plate; Mixture pressure can obtain certain mitigation, and then further through the stopping of the second mixing chamber top blind flange, mixture pressure further obtains relaxing; The mixture pressure of therefore going out from cover plate can be less; 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 like this.

Preferably, the diameter of venthole is 1.5～2.5mm on the said homogenizing plate.

The distance of the said homogenizing plate of distance is 9mm～11mm around the said cover plate upper surface, and the distance of the said homogenizing plate of said cover plate upper surface center highest point distance is 11mm～12mm.

Fire hole on the said 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: the top through in gas mixing chamber is provided with cover plate, and fire hole on the cover board is set then, and 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.
