Abstract
The utility model discloses a full premix combustor belongs to a pot boiler burner technical field. This combustor includes air cleaner, fan, wind channel, control valve, air cleaner cross the thick level of outer surface coating and cross the filter pulp, go on just imitating filtering to the air that gets into the combustor, HV folded filter paper has been wrapped up in to the filter inner wall, carries out the high efficiency filter once more to the air, the air after the filtration mixes with gas entering mixing chamber, the gaseous lurex combustion head surface after combustion that arrives behind the intensive mixing gas. This device adopts multi -stage filtration, and combustion air is of high quality, avoids the emergence of each various problem when lurex combustion head surface burn, can effectual improvement burning and mass of exhaust.
Description
Technical field
The utility model relates to a kind of burner, in particular to a kind of all-premixing burner, belongs to boiler-burner technical field.
Background technology
In Boiler Manufacturing Enterprise, especially for gas fired-boiler, it is necessary to be equipped with corresponding burner; Along with country is more strict to environmental requirement, NOx emission requires more and more lower; And the minimum quantity discharged of the NOx of all-premixing burner can reach 9PPm; Meet environment protection emission requirement completely; Pre-mixed fuel and air being carried out mixes entirely in advance entirely, and carried out accurate regulation and control, ensure that the mixing completely of combustion gas and air, make burning more abundant, the steel fiber combustion head that recent years occurs forms combustion flame on its surface, surface combustion technology is adopted to be reduce the effective way of burner NOx emission concentration, due to the special construction of steel fiber combustion head, combustion air be it is also proposed higher requirement, impurity in combustion air can affect the performance of steel fiber combustion head normal function, thus affects burning and discharge quality.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned defect of existing all-premixing burner existence, it is provided that a kind of all-premixing burner.
For realizing the purpose of this utility model, have employed following technical scheme: a kind of all-premixing burner, comprise air filter, blower fan, air channel, control valve, described air filter is crossed outside surface and is wrapped up thick level filter cotton, the air entering burner is carried out primarily efficient filter, strainer inwall is wrapped with HV folded filter paper, air is efficiently filtered again, air after filtration enters mixing chamber with combustion gas and mixes, gas after abundant mixed gas arrives the surface afterfire of steel fiber combustion head, further, flow-disturbing fan blade disc it is provided with behind premixer, further, steel fiber combustion head Fibre diameter used is 40-45 ��m.
Positive Advantageous Effects of the present utility model is: this device adopts cascade filtration, and combustion air quality is good, avoids the generation of various problem when steel fiber combustion head surface combustion, it is possible to effective raising is burnt and discharge quality.
Accompanying drawing explanation
Fig. 1 is front-view schematic diagram of the present utility model.
Fig. 2 is schematic top plan view of the present utility model.
Embodiment
In order to explain enforcement of the present utility model more fully, it is provided that embodiment of the present utility model. These embodiments are only to elaboration of the present utility model, do not limit scope of the present utility model.
By reference to the accompanying drawings that the utility model is detailed further explanation, is respectively labeled as in accompanying drawing: 1: air filter, 2: blower fan, 3: air channel, 4: gas gun, 5: fan blade disc, 6: premixer, 7: steel fiber combustion head, 8: electrically-controlled component, as shown in drawings, a kind of all-premixing burner, comprise air filter 1, blower fan 2, air channel 3, control valve, control valve adopts automatically controlled butterfly valve, cross outside surface at air filter 1 and wrap up thick level filter cotton, the air entering burner is carried out primarily efficient filter, strainer inwall is wrapped with HV folded filter paper, this part does not illustrate in the drawings, air is efficiently filtered again, air after filtration enters mixing chamber 6 and mixes with combustion gas, flow-disturbing fan blade disc 5 it is provided with behind premixer 6, ensure that air and combustion gas fully mix, gas after abundant mixed gas arrives steel fiber combustion head 7 surface afterfire, steel fiber combustion head Fibre diameter used is 40-45 ��m. this device in use ignitron first discharge a small amount of Sweet natural gas, ignition electrode rod release ignition arc is ignited formation ignition flame, now main tracheae discharge a large amount of Sweet natural gas and air proportion mixed in advance after be diffused into steel fiber combustion head surface and burn, form main flame, along with the increase of Sweet natural gas butterfly valve and air butterfly valve opening angle, the Sweet natural gas of release and air mixture amount increase, and burning load strengthens gradually, this device utilizes the flexibility of metal fiber burner, makes the head of burner can make any shape. such as flat-section, round shape, cone, spill, spherical etc., evenly pre-mixed due to the even ventilation property of metal fibre interlacement and combustion gas and air, very stable and uniformity of temperature profile of burn, it does not have localized hyperthermia's existence, therefore inhibits the generation of NOx. pre-mixing has again enough uncontaminated air supplies, therefore the overall discharge of the C0 of this device is also low. the utility model structure is simple, and convenient operation, only operates boiler implosion cabinet switch and can automatically open operation at user scene, all-premixing burner can realize proportion adjustment, and maximal regulated scope reaches 20-100%.
After in detail enforcement mode of the present utility model being described, the personage being familiar with this technology can be well understood to, do not depart from above-mentioned claim with spirit under can carry out various change and amendment, all any simple modification, equivalent variations and modifications above embodiment done according to technical spirit of the present utility model, all belong to the scope of technical solutions of the utility model, and the utility model is not also limited to the enforcement mode of example in specification sheets.
