Description
Technical field
This utility model relates to burner, is specifically related to tinsel grid low NO。
Background technology
Along with industrial expansion, atmospheric pollution increasingly becomes threat global problem, especially in thermal power plant and priority industry field, need disposal of pollutants source (gas fired-boiler) is implemented desulphurization denitration transformation, natural gas is in boiler combustion process, the oxynitride (Nox) produced from burner can be divided into two big classes, and a class is called temperature mode Nox, is that the nitrogen in air is at high temperature formed with oxygen；Another kind of it is called fuel type Nox, it is that the nitrogen in fuel at high temperature reacts formation with oxygen, owing to the nitrogen content in natural gas is less, it is main to control temperature mode Nox that gas fired-boiler reduces Nox discharge, situation when natural gas is burnt by American scientist in different temperatures situation has carried out observation analysis, find that Hydrocarbon was burnt almost without the time under 1100～1200 celsius temperatures, and fuel just has enough time after-flame pollutant Hydrocarbon when about 800 degree furnace temperature, avoid the generation of Nox simultaneously。But existing transformation one-time investment and operating cost are expensive, and install complexity, it is difficult to be accepted by a lot of medium-sized and small enterprises。
Therefore, the problem that improvement cost low-nitrogen discharged in the course of the work is high, install inconvenience deposited by the burner in current existing gas fired-boiler。
Utility model content
Technical problem to be solved in the utility model is the problem that the burner in existing gas fired-boiler exists that improvement cost low-nitrogen discharged in the course of the work is high, install inconvenience。
In order to solve above-mentioned technical problem, this utility model be employed technical scheme comprise that a kind of tinsel grid low NO of offer, including the combustor being built in boiler, described combustor includes combustor body and stretches out the outlet connections part of described combustor body front end, described outlet connections part is set with combustion head, described combustion head includes import connection member and fixes, with described import connection member, the metal gauze combustion head being connected, described import connection member is reserved burning head bore rear enclosure through boiler and is contained on described outlet connections part and fixing with the body outer wall of described boiler is connected, described metal gauze combustion head is surrounded by the metal gauze in lattice-shaped and surrounds。
In such scheme, in described outlet connections part, the import department near described metal gauze combustion head is provided with diversion fan, drives described diversion fan to rotate from the air-flow of this internal blowout of described combustor。
In such scheme, described diversion fan is interval with several guide vanes。
In such scheme, the outside of described import connection member is protruded and is provided with fixing plate, and described fixing plate is connected with the body outer wall of described boiler。
In such scheme, described metal gauze combustion head adopts ferrochrome almag material, and forms multiple layer metal screen net structure in vacuum high temperature furnace wire drawing。
In such scheme, described combustion head presents flat or drum type brake。
In such scheme, the thickness of described metal gauze combustion head is 1.2～1.5 millimeters。
In such scheme, the ignition temperature at described metal gauze combustion head place is 800 degrees Celsius。
This utility model, when combustor is under fired state, the surrounding of metal gauze combustion head is blue flame and is uniformly distributed, flame stabilization, and temperature is at 800 degrees centigrade, can there is the abundant after-flame pollutant Hydrocarbon of enough time, avoid the generation of Nox simultaneously, effectively reduce the generation of dusty gas, simple in construction, easy for installation, environmentally-friendly sanitary。
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the side schematic view of diversion fan in this utility model。
Detailed description of the invention
Below in conjunction with Figure of description, this utility model is described in detail。
As shown in Figure 1, this utility model provides a kind of tinsel grid low NO, including the combustor being built in boiler (not shown), combustor includes combustor body 10 and stretches out the outlet connections part 11 of combustor body 10 front end, when combustor is in fired state, the mixing gas of combustion gas and air sprays from outlet connections part 11。Outlet connections part 11 is set with combustion head, combustion head includes import connection member 21 and the metal gauze combustion head 20 being fixedly linked with import connection member 21, and wherein import connection member 21 is contained on outlet connections part 11 through the reserved combustion head borehole jack of boiler and is connected with the body outer wall of boiler。Preferably, the outside of import connection member 21 is protruding with fixing plate 22, and import connection member 21 is connected by fixing plate 22 is fixing with the body outer wall of boiler。
Metal gauze combustion head 20 is surrounded by the metal gauze in lattice-shaped and surrounds, the mixing gas of combustion gas and air from outlet connections part 11 spray into metal gauze combustion head 20 and uniform from mesh spray time, at the outer lattice structure homogenous combustion surrounding himself of metal gauze combustion head 20。In this utility model, metal gauze combustion head 20 adopts ferrochrome almag material, and form multiple layer metal screen net structure in vacuum high temperature furnace wire drawing, the thickness of preferred metal gauze combustion head 20 is 1.2～1.5 millimeters, lightweight, good permeability, high temperature resistant, rust resistance and corrosion resistance, service life was up to 15 years, it is adaptable to multiple low carbon, low nitrogen burning situation。
This utility model, metal gauze standard size 20 " x48 ", the shape of combustion head can present flat or drum type brake as required, expands the scope of application, and the ignition temperature at metal gauze combustion head 20 place is 800 degrees Celsius。During burning, metal gauze combustion head 20 surrounding is blue flame and is uniformly distributed, flame stabilization, and at this temperature, fuel just has enough time after-flame pollutant Hydrocarbon, avoids the generation of Nox simultaneously。
