Description
Technical field
The utility model relates to the boiler technology field, and a kind of vertical type primer-generating combustion apparatus of the fire in a stove before fuel is added particularly is provided for the grate furnace fire grate.
Background technology
At present, mechanization fire coal (grate furnace) fire grate of widespread usage mainly is divided into reciprocal drive fire grate and chain link drive fire grate two big classes on structure.The course of work of this class fire grate is the coal that enters from the fire grate front end to be delivered to the fire grate tail end finish the burning of coal process slag is discharged.Its shortcoming is: one, catching fire of coal fuel is to only depend on the radiant heat of chimney arch to ignite, and catching fire is that aspect to round floor from the coal, opposite with direction of ventilation, is in the limited state that catches fire, unfavorable to burning, and will cause burn incompletely; Two, lower floor's coal fuel is at last and catches fire, so will cause duff fuel to leak down from the furnace grate ventilation hole, causes waste.At above-mentioned fire grate shortcoming, number of patent application is overcome for 200510063653.5 patent application provides a kind of burn-out grate of grating capable of generating bottom.But the burn-out grate of described grating capable of generating bottom, since the fire grate body is anterior as forming the part that fire in a stove before fuel is added device takes place, taken the anterior active combustion of fire grate space, and its deficiency is that fire grate active combustion space is reduced.
The utility model content
The technical problems to be solved in the utility model is, the burn-out grate of existing grating capable of generating bottom is anterior as forming the part that fire in a stove before fuel is added device takes place with the fire grate body, taken fire grate active combustion space, front portion and causes deficiency that fire grate active combustion space is reduced.
For solving the problems of the technologies described above technical solution adopted in the utility model be, a kind of vertical type primer-generating combustion apparatus is provided, it by the vertical square tube shape coal bunker of the vertical fixed grate plate rack of double as, place vertical reciprocating grate and flue in the described coal bunker to form, on A, the described coal bunker, in have two ends to be separately fixed at fire grate segment mounting rail on the left and right sidewall of described coal bunker; B, described vertical reciprocating grate is by the vertical fixed grate plate rack of described coal bunker double as, in described coal bunker rear lower and described coal bunker can be relative before, after move horizontally the vertical moving grate plate rack of cooperation, be fixed on the fixed grate film on the described coal bunker fire grate segment mounting rail, be fixed on the movable furnace grate plate on the described moving grate plate rack fire grate segment mounting rail and be fixed on a described coal bunker left side, vertical reflection arch on the right side wall is formed, described moving grate plate rack is the vertical support body on slope, front side, fire grate segment mounting rail on the described moving grate plate rack is distributed in place, slope, described front side, the corresponding slope that is with the fire grate segment mounting rail on the described moving grate plate rack of described coal bunker upper fire-grating sheet mounting rail distributes, the reciprocal grate working face that described fixed grate film and movable furnace grate plate constitute is stairstepping, described reflection arch and the corresponding cooperation of described stairstepping working face; C, described flue are the flue that the broach shape distributes that is parallel to each other, and corresponding with the described reflection arch top respectively flue fixed via in described flue one termination cooperates, corresponding with the described coal bunker front side wall respectively flue fixed via of the other end cooperates; Behind described reflection arch upper end and the described coal bunker, the front side wall spacing is respectively described vertical type primer-generating combustion apparatus fuel and divides inflow entrance and boiler oil to divide inflow entrance; Described reflection arch lower end and described stairstepping working face lower end, described coal bunker front side wall spacing are respectively described vertical type primer-generating combustion apparatus completing combustion state fire in a stove before fuel is added outlet and send fuel outlet to boiler.
The utility model compared with the prior art, since vertical type primer-generating combustion apparatus by the vertical square tube shape coal bunker of the vertical fixed grate plate rack of double as, place vertical reciprocating grate and flue in the described coal bunker to form, the fuel that divides inflow entrance in the described coal bunker by described vertical type primer-generating combustion apparatus fuel, along described vertical reciprocating grate stairstepping working face operation burning, to the described stairstepping working face lower end formation completing combustion state fire in a stove before fuel is added, through described vertical type primer-generating combustion apparatus completing combustion state fire in a stove before fuel is added outlet, fall on the boiler grate firing fire grate; The fuel that divides inflow entrance in the described coal bunker by described boiler oil, in described coal bunker, pass space between the described flue, send fuel outlet through described to boiler, fall on the boiler grate firing fire grate and run on the corresponding described completing combustion state fire in a stove before fuel is added below boiler send fuel outlet with boiler grate furnace row, realized fuel in the described coal bunker before entering burner hearth, form bottom for the fire in a stove before fuel is added that ignites, upper strata for covering the coal seam state, and after entering boiler furnace, before burning, keep, it is identical with direction of ventilation to the upper strata by bottom to burn. alwaysIts beneficial effect is, with the part of coal bunker as the composition vertical type primer-generating combustion apparatus, not only make the vertical type primer-generating combustion apparatus structure comparatively simple, and do not take the anterior active combustion of fire grate space, overcome in the burn-out grate of existing grating capable of generating bottom the fire grate body is anterior as forming the part that fire in a stove before fuel is added device takes place, taken fire grate active combustion space, front portion and cause deficiency that fire grate active combustion space is reduced.Be easier to transformation to old-fashioned grate firing boiler.
