Description
Technical field
It the utility model is related to a kind of adherent wind wind regime introducing device.
Background technology
Original designs adherent wind airduct entrance and is connected with secondary air box entrance controllable register, and the source of its wind is secondary hot-air.
But secondary hot-air temperature is higher, it is impossible to slows down the high temperature corrosion in burner hearth.If adherent wind wind regime is changed to back-end ductwork
Low-temperature flue gas, from boiler back end ductwork introduce all the way pipeline to adherent wind airduct entrance.Low-temperature flue gas can just slow down adherent combustion
Burn, reduce the high temperature corrosion of both walls.
The content of the invention
In order to provide a kind of adherent wind wind regime of low temperature, slow down high temperature corrosion of the adherent burning for side wall, prolonged boiler
Service life, to achieve the above object, the technical solution adopted in the utility model are as described below.
A kind of adherent wind air supply device, back-end ductwork are entered by the adherent wind airduct of low-temperature flue gas pipeline and adherent wind system
Mouth connection, adherent wind system have one or more adherent wind airduct entrances；Adherent wind airduct entrance passes through pipeline and adherent wind
Spout connects.
According to described adherent wind air supply device, installed respectively at left and right sides of the burner nozzle of the front wall of burner hearth and rear wall
There is an adherent wind snout of row front-back wall；
It is provided with the adherent wind snout of side wall of A rows × B column matrix arrangement on left side, right-side wall from bottom to top respectively.
According to described adherent wind air supply device, the adherent wind of two row front-back walls installed on described front wall and rear wall sprays
Mouthful, the quantity of each row is all 3.
It is contour from bottom to top per the adherent wind snout of a line front-back wall according to described adherent wind air supply device, A 4, B 2
Distribution.
The advantages of the utility model, is as described below.
Original designs adherent wind airduct entrance and is connected with secondary air box entrance controllable register, and the source of its wind is secondary hot-air,
Burner nozzle flame adherent burning for a long time, it is possible to the high temperature corrosion of side wall can be caused, shorten burner hearth service life.This
With regard to needing a kind of means for mitigating high temperature corrosion, it can slow down adherent burning by introducing low-temperature flue gas, mitigate what is thus brought
High temperature corrosion.Adherent wind wind regime is now changed to afterbody low-temperature flue gas, introducing pipeline all the way from boiler back end ductwork delivers to adherent wind
Airduct entrance.Low-temperature flue gas can slow down adherent burning, reduce the high temperature corrosion of both walls.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.

Fig. 3 is the adherent wind snout distribution schematic diagram of left and right side wall.
In accompanying drawing：1st, burner hearth；2nd, adherent wind；3rd, adherent wind airduct entrance；4th, low-temperature flue gas pipeline；5th, afterbody cigarette
Road；6th, the adherent wind snout of front-back wall；7th, the adherent wind snout of side wall.
Embodiment
Embodiment
Accompanying drawing 1 is described further below in conjunction with the accompanying drawings.
A kind of adherent wind system provided by the invention, including the air source apparatus that is sequentially connected by adherent wind air channel and adherent
Wind nozzle, the adherent wind nozzle are located at the front-back wall of face-fired boiler, the edge of side wall.
A kind of adherent wind air supply device, the patch for passing through low-temperature flue gas pipeline 4 and adherent wind system from the flue of boiler tail
Wall wind airduct entrance 3 connects, and adherent wind system has one or more adherent wind airduct entrances；Adherent wind airduct entrance 3 passes through
Pipeline is connected with adherent wind snout.
Further, according to the actual requirements, can be installed respectively at left and right sides of the burner nozzle of the front wall of burner hearth 1 and rear wall
There is the adherent wind snout 6 of a row front-back wall.
It is provided with the adherent wind snout 7 of side wall of A rows × B column matrix arrangement on left side, right-side wall from bottom to top respectively.It is described
Front wall and rear wall on the two adherent wind snouts of row front-back wall installed, the quantity of each row is all 3.Preferably, A is for 4, B
2, per the contour distribution from bottom to top of the adherent wind snout 6 of a line front-back wall.
The adherent wind of front-back wall is arranged on front wall and rear wall, can be ensured on the premise of being not added with inner member inside burner hearth
Realize that adherent wind flows parallel to side water wall, being arranged in side wall air-flow so as to efficiently solving adherent wind is difficult to parallel to water
The problem of cold wall flows, substantially reduce the risk of coking and high temperature corrosion.
This adherent wind air supply device is simple in construction, easy to implement, by the way that adherent wind system is arranged at into front-back wall, side wall
Edge, by using high-pressure air source and specific nozzle, so as to effectively prevent the problem of water-cooling wall coking and high temperature corrosion.
Original adherent wind airduct entrance of design is connected with secondary air box entrance controllable register, and the source of its wind is second heat
Wind, burner nozzle flame burned for long time, it is possible to the high temperature corrosion of side wall can be caused, shorten burner hearth service life.
In order to mitigate high temperature corrosion, high temperature corrosion can be mitigated by introducing low-temperature flue gas from back-end ductwork 5.By adherent wind
Wind regime is changed to afterbody low-temperature flue gas, from boiler back end ductwork 5 introduce all the way pipeline to adherent wind airduct entrance 3.Adherent wind airduct
Entrance 3 is connected with adherent wind snout again by pipeline, and low-temperature flue gas can slow down adherent burning, and the high temperature for reducing both walls is rotten
Erosion.
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality
New design and protection domain is defined, common in this area on the premise of the utility model design conception is not departed from
The all variations and modifications that engineers and technicians make to the technical solution of the utility model, guarantor of the present utility model all should be fallen into
Protect scope.
