The fuel gas energy-saving combustor is characterized in that the appearance of an outer shell (11) of the combustion chamber (1) and the appearance of the air sieve (5) are conical and are matched with each other, and a plurality of air inlets (51) are formed in the air sieve (5). Compared with the prior art, the fuel gas energy-saving combustor can avoid the mutual collision of flames in the combustion process, combustion noise is greatly lowered, wind power losses are reduced, and the fuel gas utilization rate and combustion efficiency are greatly improved.

Description

A kind of energy-saving gas burner

Technical field

The present invention relates to a kind of burner, a kind of energy-saving gas burner is especially set.

Background technology

At present, the gas burner using on the market divides natural wind burner and the large class of the combustion-supporting burner two of blower fan, and the combustion-supporting burner of blower fan, according to the difference of its combustion system, can be divided into again pre-mixing furnace end and non-pre-mixing furnace end.Under premixed combustion mode, the gentle proportioning of oxygen (intake) is difficult to hold, its thermal efficiency is all difficult to the level that reaches desirable conventionally, thus at present large-scale catering unit is used general be all the cylindrical burner (be commonly called as and hook wind furnace head: centre fires, around air intake) of non-premix.Although current hook wind furnace head ratio of combustion is more abundant, firepower is larger, but be cylindrical right angle air intake mode due to what adopt, when burning, the intensity of flame head-on collision is large, frequency is high, has produced thus huge noise, simultaneously, because this burner will ensure abundant burning, not only require the space of burner hearth enough large, and generally all to need to join power be blower fan more than 250W.

Summary of the invention

Technical problem to be solved by this invention solves the flame head-on collision phenomenon that existing cylindrical burner produces in combustion process, and the energy-saving gas burner that a kind of combustion noise is little, wind loss is little and efficiency of combustion is high is provided.

The present invention solves the problems of the technologies described above adopted technical scheme: a kind of energy-saving gas burner, the blast pipe that it comprises combustion chamber, is communicated with bottom, combustion chamber, and the vertical main fiery air inlet pipe that runs through successively blast pipe, combustion chamber, wherein combustion chamber lateral surface is provided with ever-burning flame air inlet pipe, inside is embedded with pneumatic jig, in pneumatic jig, be provided with the shower nozzle with fumarole, shower nozzle bottom is connected with the upper end of main fiery air inlet pipe, it is characterized in that: the profile of described combustor outer casing and pneumatic jig is taper shape, and coupling, arranges multiple fresh air inlets on described pneumatic jig mutually.

For making this energy-saving gas burner can meet the different requirements of different user to combusting firepower, at the air inlet place of described main fiery air inlet pipe, flow control valve is set respectively, air inlet place at described blast pipe arranges volume control damper, can regulate combusting firepower by adjustment of combustion gas flow or intake like this, meet different burning demands.

For ease of the discharge such as greasy dirt, discharge, facilitate regular maintenance, described main fiery air inlet pipe vertically below a sewage draining exit is set.

As further improvement, can use at described sewage draining exit place plug or valve sealing, to prevent that greasy dirt, discharge etc. from splashing into operating environment, avoid natural wind to pour in down a chimney from sewage draining exit, impact burning.

Compared with prior art, the invention has the advantages that: in the energy-saving gas burner in the present invention, adopt conical pneumatic jig, and the conical burner matching with it, can make the wind entering from blast pipe evenly supply with burning along the fresh air inlet of conical pneumatic jig, thereby the direction that the main fire that makes to burn is vertically upward along the fresh air inlet of conical pneumatic jig enters normal combustion, can avoid the mutual head-on collision of combustion process Flame, greatly reduce combustion noise, reduce wind loss, greatly improve combustion gas utilization rate and efficiency of combustion.

Detailed description of the invention

Below in conjunction with accompanying drawing, embodiment is described in further detail the present invention.

As shown in Figure 1, 2, energy-saving gas burner in the present invention, the blast pipe 2 that it comprises combustion chamber 1, is communicated with 1 bottom, combustion chamber, and the vertical main fiery air inlet pipe 3 that runs through successively blast pipe 2, combustion chamber 1, wherein combustion chamber 1 lateral surface is provided with ever-burning flame air inlet pipe 4, inside is embedded with pneumatic jig 5, in pneumatic jig 5, be provided with the shower nozzle 6 with fumarole 61, shower nozzle 6 bottoms are connected with the upper end of main fiery air inlet pipe 4, wherein said combustion chamber 1 shell 11 is taper shape with the profile of pneumatic jig 5, and coupling, arranges multiple fresh air inlets 51 on described pneumatic jig 5 mutually.For making this burner meet different user, the difference of firepower is required: air inlet 31 places in described main fiery air inlet pipe 3 arrange flow control valve 32; Air inlet 21 places at described blast pipe 2 arrange volume control damper 22.For ease of regular maintenance, described main fiery air inlet pipe 3 vertically below a sewage draining exit 33 is set, this sewage draining exit 33 can be with plug or valve sealing.

In use procedure, first open ever-burning flame gas valve, combustion gas enters the region between combustor outer casing 11 and conical pneumatic jig 5 by ever-burning flame air inlet pipe 4, starting electronic ignition equipment (or passing through manual ignition) lights the ever-burning flame in combustion chamber 1, start combustion fan, make ever-burning flame in combustion chamber 1, enter normal combustion state.Then open main fiery gas valve, combustion gas is entered after shower nozzle 6 by main fiery air inlet pipe 3, sprays, after igniting by ever-burning flame from fumarole 61 along continuous straight runs to combustion chamber 1, under the effect of combustion fan, the direction that main fire is vertically upward along the fresh air inlet 51 of conical pneumatic jig 5 enters normal combustion.
