The sub-high speed thermostatic burner causes the combustion-supporting air and the doped cold air to be independently controlled, the two channels are used for supplying the air, the combustion-supporting air ensures the gas to be burnt in the combustion chamber, the doped cold air is divided into two parts to enter, one part enters into the combustion chamber through small holes circumferentially distributed on the burning cylinder so as to ensure an outlet to have no fire, and the other part enters into the nozzle brick through the gap between the burning cylinder and the nozzle body so as to achieve the purpose of the attemperation.
Description
Technical field
The present invention relates to the burner field, especially relate to a kind of inferior high velocity temperature adjusting burner that is used on the heat-treatment furnace.
Background technology
At present, on various heat treatment of workpieces stoves, the basic high combustion rate burner that adopts is as burner, coal gas flows in combustion barrel according to a certain percentage with air and mixes, and mist is at cylinder roasting 80%-95%, and all the other are completing combustion in burner hearth, a large amount of hot gas are with the high speed ejection of 100-300m/s, in stove, produced strong convection heat transfer' heat-transfer by convection, and because the strong agitation of a large amount of gases makes the interior temperature of stove reach even.Yet, there are following two point defects in actual use in this kind mode: 1. because some flame enters the burner hearth burning, just inevitably having flame directly touches workpiece for this, causes the localized hyperthermia of workpiece, and during low-temperature condition, temperature is difficult for regulating; 2. because the high speed of flame flows out, can produce bigger noise, very unfavorable to site environment.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of inferior high velocity temperature adjusting burner at problems of the prior art, its objective is to guarantee the burner exit flames of anger, and temperature regulating range is big, and the temperature in the stove is even, and simultaneously, noise is lower.
Technical scheme of the present invention is the inferior high velocity temperature adjusting burner of this kind, comprise the burner body and the burner block that are connected, be provided with the combustion chamber in the burner body, being positioned at described burner body is provided with combustion-supporting airduct and mixes cool air hose, and combustion-supporting airduct and mix cool air hose and divide two passes supply air, coal gas and combustion air are struck sparks in the combustion chamber internal combustion by the ignition that is arranged on the burner body, enter the combustion chamber from the described cold wind part of mixing of coming out the cool air hose of mixing, make the further mixed combustion of coal gas, rise simultaneously and transfer short flamed purpose, another part is mixed cold wind and is entered burner block by the slit between combustion barrel and the burner body, plays the purpose of temperature adjustment.
The passage that described burner body is connected with gas pipe is provided with gas stop valve, and by PLC control, gas stop valve receives and is installed in the signal that the flame detector on the burner body sends.
Circumferentially being distributed with of described combustion barrel is convenient to mix the aperture that cold wind enters combustion barrel.
Described little centerline hole and horizontal direction angle β are 35 °-50 °.
A kind of inferior high velocity temperature adjusting burner with above-mentioned special construction has the following advantages:
1, the inferior high velocity temperature adjusting burner of this kind make combustion air, mix cold wind and control separately, divide two passes supply air, combustion air makes coal gas in the combustion chamber internal combustion, mixes cold wind and divides two parts to enter, and a part enters the combustion chamber by the aperture that circumferentially distributes on the combustion barrel, guarantee imperfect combustion coal gas completing combustion, rise simultaneously and transfer short flamed purpose, guarantee the exit flames of anger, a part enters burner block by the slit of combustion barrel and burner body, mix with burning gases, play the purpose of temperature adjustment.
2, the inferior high velocity temperature adjusting burner of this kind has guaranteed that the muzzle velocity of combustion gas is low to moderate about inferior high speed 100m/s, thereby has reduced noise by the rational allocation of combustor exit diameter; Simultaneously, when flame detector detects burner flame because extraneous cause when flame-out phenomenon occurring, gas stop valve can cut off the coal gas of this burner automatically, avoids occurring because the danger that gas leak is blasted in the stove has guaranteed the safety in production of stove.
3, the inferior high velocity temperature adjusting burner of this kind is easy to operate, and temperature regulating range is big.Only mix the size of cold blast rate by adjusting, the burner block gas outlet temperature is changed in 300-1000 degree scope, temperature is easily regulated control, and is reliable; Energy resource consumption is low, and the coal gas consumption is little, and simultaneously, temperature homogeneity improves greatly.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:

The specific embodiment
By the combination of structure shown in Fig. 1-2 as can be known, the inferior high velocity temperature adjusting burner of this kind comprises burner body 5 and the burner block 8 that is connected, be provided with combustion chamber 6 and combustion barrel 7 in the burner body 5, the 3 row's apertures 12 that circumferentially distributing on the combustion barrel 7, aperture 12 is 45 ° with horizontal direction angle β.Be positioned at burner body 5 and be provided with combustion-supporting airduct 3 and mix cool air hose 4, and combustion-supporting airduct 3 and mix cool air hose two passes supply in 4 fens air.Combustion air make coal gas in the combustion chamber 6 internal combustion.Coal gas and combustion air are by being arranged on the ignition 9 sparking burnings on the burner body 5.Mixing cold wind divides two parts to enter, part cold wind enters the combustion chamber along the aperture 12 that circumferentially distributes on the combustion barrel 7 with horizontal direction angle β angle at 45, guarantee imperfect combustion coal gas completing combustion, simultaneously, because the increase of air quantity, play and transfer short flamed purpose, guarantee the combustion barrel 7 exit flames of angers; Part cold wind flows along combustion barrel 7 walls, reduce the temperature of combustion barrel 7 walls, and enter burner block 8 by the slit 14 of combustion barrel 7 and burner shell, the high-temperature gas that comes out with combustion chamber 6 mixes, by the adjusting of cold blast rate size, can regulate burner block 8 gas outlet temperatures easily.When gas sprays at a high speed, can produce noise,, reduce the speed of air-flow, simultaneously noise be eliminated by adjusting the size of combustion chamber 6 outlets 13 diameters.Can be observed the flame burning situation by peep-hole 11.
The passage that burner body 5 is connected with gas pipe 2 is provided with gas stop valve 1, and by PLC control, gas stop valve 1 receives and is installed in the signal that the flame detector 10 on the burner body 5 sends.When flame detector 10 detects burner flame because extraneous cause when flame-out phenomenon occurring, gas stop valve 1 can cut off the coal gas of this burner automatically, avoids occurring because the danger that gas leak is blasted in the stove guarantees the stove safety in production.
