The most logical cigarette vertical type primer-generating combustion apparatus
Technical field
This utility model relates to boiler technology field, stands particularly to cigarette logical under the one for the grate furnace fire grate offer fire in a stove before fuel is added
Formula primer-generating combustion apparatus.
Background technology
At present, coal-fired (grate furnace) fire grate of commonly used mechanization, be broadly divided into from structure reciprocal transmission fire grate and
The big class of chain link drive fire grate two.The work process of this kind of fire grate is the coal entered from fire grate front end to be delivered to fire grate tail end complete coal
Combustion process by slag discharge.Its shortcoming is: one, catching fire of coal fuel is only to ignite by the radiant heat of chimney arch, catch fire be from
Coal face layer to round floor, contrary with direction of ventilation, is in limited state of catching fire, unfavorable to burning, will result in insufficient combustion
Burn;Two, lower floor's coal fuel is in and finally catches fire, and leaking down from furnace grate ventilation hole so will result in duff fuel, causing waste.Pin
To above-mentioned fire grate shortcoming, number of patent application be 200920149884.1 patent application provide a kind of vertical type primer-generating burning dress
Put, can come to be overcome.But described vertical type primer-generating combustion apparatus, due to flue for design in coal bunker, horizontal boiler fire
The flue of the comb teeth-shaped distribution that is parallel to each other below material shunting entrance, its deficiency is to be formed with the coal of whereabouts in coal bunker to intersect, easily
Coal heating is caused volatile component in coal separate out or ignite by chute blockage and generation;Supplied flue gases is had bigger by flue comb spacer structure
Resistance.
Utility model content
The technical problems to be solved in the utility model is, existing vertical type primer-generating combustion apparatus, falls in flue and coal bunker
Coal formed and intersect, easy chute blockage and produce and cause in coal volatile component separate out or ignite coal heating;Flue comb spacer structure
Supplied flue gases is had the deficiency of bigger resistance.
For solving above-mentioned technical problem, technical solution adopted in the utility model is, it is provided that under one, logical cigarette is vertical broadcasts
Fire in a stove before fuel is added burner, it by double as vertical fixed grate plate rack vertical type square tubular coal bunker, be placed in described coal bunker vertical
Reciprocal grate and flue composition, described flue is lower logical cigarette flue, has secondary in described coal bunker above described lower logical cigarette flue
Air compartment, described lower logical cigarette flue is positioned at described vertical reflection by the vertical reflection arch of described vertical reciprocating grate and described coal bunker
The membrane wall arch cigarette wall composition in arch front, described membrane wall arch cigarette wall and the left and right sidewall solid welding of described coal bunker, upper end and institute
The upper header stating vertical reflection arch connects, and lower end is connected with membrane wall arch cigarette wall lower collecting box, under described membrane wall arch cigarette wall
Header is described lower logical cigarette flue outlet with the lower collecting box spacing of described vertical reflection arch;Described secondary air chamber is by described membrane wall
Above arch cigarette wall, double as the air compartment plate of described lower logical cigarette vertical type primer-generating combustion apparatus fuel dividing guide plate and double as boiler combustion
Material dividing guide plate air compartment plate composition, double as described lower logical cigarette vertical type primer-generating combustion apparatus fuel dividing guide plate air compartment plate and
Double as the air compartment plate of boiler oil dividing guide plate and the left and right sidewall solid welding of described coal bunker, described coal bunker left or right sidewall correspondence institute
State and at secondary air chamber, be welded with secondary wind access tube;Arch wall above described lower logical cigarette flue entrance on described vertical reflection arch
Corresponding position above part and described membrane wall arch cigarette wall, is welded with through described secondary air chamber and the injection of described lower logical cigarette flue
Secondary wind bend pipe;Described membrane wall arch cigarette wall lower collecting box and described coal bunker front side wall spacing are for send fuel outlet to boiler;?
Described coal bunker is interior, described send corresponding position above fuel outlet to have coal moving roller, described coal moving roller and described coal bunker left and right side to boiler
On wall, corresponding coal moving roller axle installing hole coordinates.
This utility model compared with the prior art, owing to being designed with described lower logical cigarette flue, described secondary air chamber and described
Coal moving roller structure, it provides the benefit that, the coal fallen in described lower logical cigarette flue and coal bunker is formed without and intersects, not chute blockage, it is to avoid
Volatile component in coal is caused to separate out or ignite coal heating;Described secondary air chamber overcomes described lower logical cigarette flue supplied flue gases
While resistance, one is can be combustion-supporting to the flue gas entered in described lower logical cigarette flue, and two can ignite again the most fully catches fire
Fire in a stove before fuel is added coal seam.
