Abstract
The utility model discloses a be used for hot -blast furnace heating to use combustor, including the blunt body of combined type whirl, rather than the main gas fuel passag who links to each other, nested observation in main gas fuel passag is shown on trial, attached to the main air duct axial whirl blade of main gas fuel passag front end, by " altar lamp " some firearm that ignition gas fuel passag and ignition air duct form, examines for the ease of remote monitoring and the fire of realizing automatic control to and equipment protection passageway is examined to the fire. The utility model discloses the technique is compared with prior art, has improved the burning behavior of combustor, has strengthened the mixed effect of gas, has improved the burn -off rate, shorten flame length, strengthened the flame rigidity, the life -span of product has been improved.
Description
Technical field
The utility model relates to blast furnace ironmaking field, is specifically related to a kind of for hot-blast stove heating burner.
Background technology
In blast furnace ironmaking production process, the inside to blast furnace is needed to blast a large amount of combustion airs, to promote the carrying out of ironmaking reaction in blast furnace, because blast furnace internal temperature is very high, blasting normal temperature air will cause blast furnace internal temperature sharply to decline, be unfavorable for smelting iron the carrying out reacted, therefore need the air blasting high temperature.The effect of hot-blast stove is exactly blast heating to the temperature required, thus combustion of coke is to become molten iron reduction of iron ore.
The mixed effect of current Combustion of Hot Air Furnace equipment Problems existing mainly combustion gas is poor, and burn insufficient, burner outlet flame is longer, and flame intensity is poor, easily stops working, and life of product is shorter.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of for hot-blast stove heating burner, improves the combustibility of burner, enhances the mixed effect of combustion gas, improve burn-off rate; Shorten the length of flame, enhance flame rigidity; Improve the life-span of product.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of for hot-blast stove heating burner, comprising:
One housing,
One is installed on the combined type eddy flow bluff body on housing, a main blast tube be connected with described combined type eddy flow bluff body, and is attached to the primary air passage axial rotational flow blade of main blast tube front end,
One premixed igniter, described premixed igniter comprises one and is installed on the igniting blast tube on housing and introduces the igniting air duct of igniting air,
Also comprise the primary air passage that provides air.
In a preferred embodiment of the present utility model, the bluff body cone angle of described combined type cyclone structure is 120 degree, and is provided with tangential swirl hole in bluff body inside.
In a preferred embodiment of the present utility model; also comprise protection assembly; described protection assembly comprises the remote monitoring be installed on housing and the fire realizing automatically controlling is examined, and be vertically fixed on the fire inspection equipment protection passage of fire inspection, and the observation be nested in main blast tube is shown on trial.
By technique scheme, the beneficial effects of the utility model are:
1, the utility model have employed combined type cyclone structure, effectively can form the low-temperature negative-pressure district of burning at burner outlet, improve the stability of burning while ensureing nozzle life.
2, the utility model have employed " altar lamp " flame on duty, effectively overcomes front end system pressure oscillation to the impact caused of burning.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
With reference to Fig. 1, a kind of for hot-blast stove heating burner, comprising: a housing, one is installed on the combined type eddy flow bluff body 1 on housing, the one main blast tube 4 be connected with described combined type eddy flow bluff body 1, and be attached to the primary air passage axial rotational flow blade 2 of main blast tube front end
One premixed igniter, described premixed igniter comprises one and is installed on the igniting blast tube 5 on housing and introduces the igniting air duct 6 of igniting air, also comprises the primary air passage 5 that provides air.
" altar lamp " igniter be made up of igniting blast tube 5 and igniting air duct 6, " altar lamp " premixed igniter is in the state of lighting in combustion all the time, there is not flame-out and de-fire when can ensure the supply pressure fluctuation of buner system front end, effectively promote the stability of burner.
Also comprise protection assembly, described protection assembly comprises the remote monitoring be installed on housing and the fire realizing automatically controlling examines 8, be vertically fixed on the fire inspection equipment protection passage 9 of fire inspection, and the observation be nested in main blast tube 4 shows on trial 7.
The bluff body cone angle of combined type cyclone structure is 120 degree, combustion air effectively can be made to form negative pressure recirculating zone at burner outlet, and be provided with tangential swirl hole in bluff body inside, main combustion gas can be made to produce strong eddy flow, increase burning turbulivity, be burn more abundant.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
