Abstract
The utility model relates to a wind pipe grate for coal-burning devices, which is composed of a wind bed, a wind pillow and an end plug wind chamber, wherein, the wind bed is composed of a plurality of wind pipes; wind holes are arranged on the wind pipes; a wind inlet is arranged on the end plug wind chamber; the wind pillow provides secondary wind for a furnace chamber. Compared with the prior art, the utility model has the advantages of no scale formation of the wind pipes, wind cooling protection of the grate, long service life, convenient operation of coal feeding and adding, good smoke prevention and dust removal of secondary wind, and simple structure, and is suitable for various hand firing life boilers and coal-burning industrial kiln furnaces.
Description
The application relates to the fire grate on a kind of coal combustion equipment, especially a kind of Wind pipe grate.
Existing combustion apparatus such as various boiler for domestic, its fire grate is water pipe furnace grate, and the disadvantage of this fire grate is exactly easily fouling in the water pipe, fouling influences boiler thermal output on the one hand, might cause fire grate to break on the other hand, therefore, water pipe furnace grate is the common weakness of various normal-pressure boilers.
The fire grate of existing various coal-fired industrial furnaces mostly is single comb formula fire grate, and the shortcoming of this fire grate is oxygen supply deficiency on the grid section, and it is insufficient to burn, and dust concentration is big.The disclosed burner of Chinese patent CN902051717, though smoke medicining dust-removing effect is good, its complex structure, manipulation strength is big.
The purpose of this utility model is to disclose a kind of simple in structure, be convenient to operate, can smoke abatement and dust control be applicable to the Wind pipe grate that various boiler for domestic and Industrial Stoves use.
Its technical scheme is as follows: fire grate is by the airduct of some hollows and be positioned at the airduct two ends and form with the plug air compartment that each airduct all communicates, on one of them plug air compartment air inlet is arranged, on each airduct some wind hole is arranged all so that ventilate, gapped leakage slag and the natural air inlet of plaing a part between airduct and the airduct to the combustion chamber.Wind hole on the whole Wind pipe grate and fire grate gap form a uniform wind bed, the burning of fire grate upper coal feeding.
For better smoke abatement and dust control, improve the thermal efficiency, on the Wind pipe grate coal seam, can establish the twice aeration mouth, this secondary wind communicates with the plug air compartment, thereby makes wind and the secondary wind can shared same air-blast device.
This Wind pipe grate, upper coal feeding is easy to operate, and fire grate wind bed gives wind even, and air-cooled protection fire grate increases the service life, and secondary wind smoke abatement and dust control effective is applicable to that various hands burn boiler for domestic and various coal-fired industrial furnace.
Below in conjunction with the embodiment accompanying drawing this application is done step detailed description.
Fig. 1 is the Wind pipe grate plane of band secondary wind.
Fig. 2 is the airduct skiagraph of Fig. 1.
Fig. 3 is the cross-sectional view of Fig. 1.
Form by the airduct 3 of several hollows referring to the accompanying drawing fire grate, preceding plug air compartment 1 and back plug air compartment 6 all communicate with each airduct, preceding plug air compartment is provided with blast orifice 7, back plug air compartment declivity forms ash accumulating chamber 9, fall into dust with windproof hole and stop up airduct, the flange 10 that can change is arranged in the end of ash accumulating chamber 9,, some wind holes 4 that make progress are arranged all on each airduct so that open ash accumulating chamber's ash disposal.Secondary wind setting among this embodiment is to extend two wind pillows 2 on preceding plug air compartment 1, this wind pillow is positioned at the both sides of fire grate wind bed, and and airduct between certain vertical range 11 is arranged, the wind hole 8 of the aspect, all oriented combustion chamber, inboard of each wind pillow 2, the section of airduct is up big and down small, and the wind hole on the airduct is positioned at the first half of airduct.
During installation, whole fire grate places in the burner hearth, and the wind pillow of both sides can be built in the hearth wall, make wind hole on the airduct and the secondary air hole on the wind pillow all blow to burner hearth, the fire grate upper coal feeding, the ash that is fallen in the airduct by the windward hole can be blown into the ash accumulating chamber of back plug along airduct, so that regularly remove.
Claims (2)
1, a kind of fire grate of coal combustion equipment, it is characterized in that this fire grate is by the airduct of some hollows be positioned at the airduct two ends and the front and back plug air compartment that communicates with each airduct is formed, on each airduct air vent is arranged, preceding plug air compartment has blast orifice, and ash accumulating chamber and ash disposal flange are arranged on the back plug air compartment.
2, Wind pipe grate as claimed in claim 1, it is characterized in that extending on the described preceding plug air compartment two wind pillows, this wind pillow is positioned at the both sides of fire grate wind bed, and and airduct between certain vertical range is arranged, the wind hole of the aspect, all oriented combustion chamber, inboard of each wind pillow.
