Description
The utility model is about fuel gas buring equipment.
At present, the fuel gas buring equipment overwhelming majority adopts the atmospheric burning type equipment of combustion gas injection part air, and the problem of its existence is that calorific intensity is little, the thermal efficiency is low, nuisance content height in the flue gas, combustion apparatus are bulky.The shortcoming of atmospheric burning type equipment is the needed air of burning all not to be sneaked into combustion gas in advance, has occurred inside and outside two flames when burning for this reason, makes NO in the flue gas
xToo high levels.In addition, this kind flame is very long, needs bigger combustion chamber, has strengthened the volume of combustion apparatus.Air suspended type flame point contact cold surface, a large amount of CO of meeting output if flame keeps clear of heated cold surface, can reduce heat transfer coefficient again, strengthen heat loss, have reduced the thermal efficiency, the waste combustion gas.The for example large-scale dining room kitchen range thermal efficiency is low, has only about 20%.Have, the induction apparatus of combustion gas injection air commonly used is difficult to institute must all be sucked induction apparatus by air at present, causes burning further not exclusively again, and nuisance content increases greatly in the flue gas.
The purpose of this utility model provides a kind of thermal efficiency height, volume is little, with the fuel gas buring equipment of the full primary air premix of air ejection combustion gas, guarantees that combustion gas and air give mixed fully and guarantee the constant rate of gas quantity and air capacity under any load.Thereby improve the content of nuisance in the thermal efficiency, the reduction flue gas, reach energy savings, the purpose of protection environment.
The purpose of this utility model is achieved by following technical proposals.
Air ejection combustion gas full premix combustion equipment of the present utility model, comprise the burning head, the combustion chamber, the igniting probe, by air nozzle, mixing chamber, the induction apparatus that sharp pipe is formed told in literary composition, proportioning valve, control valve, blower fan and air-valve are arranged on the upstream of combustion apparatus, described combustion head portion is positioned at the inlet of combustion chamber, proportioning valve is arranged on the side of burner, its outlet links to each other with the mixing tube of induction apparatus through control valve, described proportioning valve, with signal pipe it is linked to each other with tube connector, described proportioning valve matches with induction apparatus with the control valve in downstream, makes combustion gas and air keep certain proportion; The fuel gas inlet place of described proportioning valve is provided with gas electromagnetic valve, and computer controller is connected with blower fan with igniting probe, gas electromagnetic valve respectively.
Described burning head adopts metallic fiber to weave steady flame carrier, also can adopt the steady flame of porous ceramic plate to carry,
Described proportioning valve adopts pressure regulator.Cavity A in the described pressure regulator can join with tube connector,
Can join with the combustion chamber, also can join to reach different control purposes with atmosphere.
Below in conjunction with accompanying drawing the utility model is further explained and describes.
Accompanying drawing is a structural representation of the present utility model.
In the drawings, air ejection combustion gas full premix combustion equipment of the present utility model comprises blower fan 1, air-valve 2, tells sharp pipe 9 induction apparatus of forming by tube connector 3, air nozzle 4, mixing chamber 5, literary composition, burning head of being made up of anti-backfire net 10, skeleton 11, the drift net 12 that looses, steady flame carrier 13 and gas electromagnetic valve 6, proportioning valve 7, control valve 8, the parts such as probe 14, combustion chamber 15, computer controller 16 of lighting a fire.
Being right after blower fan 1 outlet is air-valve 2, and it is a common air door, can be used for regulating air quantity.The back of air-valve 2 is tube connectors 3, is used for connecting the induction apparatus in downstream.
Described air ejection device is told sharp pipe 9 by air nozzle 4, mixing chamber 5, literary composition and is formed.Air is boosted by blower fan 1, from air nozzle 4 ejection, with combustion gas mixing from gas electromagnetic valve 6, proportioning valve 7, tells through literary composition and to enter combustion head portion after sharp pipe 9 mixes fully in mixing chamber 5.
Described burning head is made up of anti-backfire net 10, skeleton 11, the drift net 12 that looses, steady flame carrier 13.It tells the downstream of sharp pipe 9 at literary composition.Skeleton 11 is mainly used to support steady flame carrier 13 and makes air-flow even with air diffuser 12.Steady flame carrier 13 can with the metal fiber carrier of 3-5 millimeters thick, ceramic fibre carrier, also can be with common burning fire hole (as circle, bar shaped, slit-shaped fire hole etc.), porous ceramic plate or other steady flame devices.Gas-air stream is through being in the anti-backfire net 10 that prevents tempering of burning head inlet, in the burning of steady flame carrier 13 places.Can be by regulating calorific intensity control combustion conditions.
Described proportioning valve 7 is pressure regulators, is connected with the gas electromagnetic valve 6 at its fuel gas inlet place in the side of blower fan 1.The epithelium that the centre of its A, two cavitys of B is clamped by two iron plates separates, and this epithelium links to each other with valve rod, aperture that can by-pass valve control.Between the tube connector before cavity A and air nozzle 4, link to each other with a signal copper pipe.When needs increase load, can drive big air-valve 2, pressure increases before making air nozzle 4, at this moment the cavity A place pressure of proportioning valve 7 also increases, epithelium drives valve lever, strengthens aperture, and gas quantity will increase and increase along with air capacity, after regulating the control valve 8 in proportioning valve 7 downstreams, can regulate the ratio of air and combustion gas and guarantee combustion gas and the constant rate of air.
Described computer controller 16 can be arranged on the side that sharp pipe 9 told in literary composition.It links to each other with the igniting probe 14 that is positioned at combustion head subordinate trip.Igniting probe 14 can send the electric pulse spark, realizes igniting automatically.When probe 14 detected less than flare up fire, computer controller 16 was given an order, and the gas electromagnetic valve 6 that will be in proportioning valve 7 population places is closed.In addition, when blower fan 1 is not worked, and ignition point not etc. during abnormality, computer controller 16 can both be closed gas electromagnetic valve 6, guarantees the burner trouble free service.
