Abstract
The utility model relates to an air inlet box of a horizontal boiler. For the large horizontal coal-fired boiler, air is supplied to a fire grate ventilating chamber through the transverse air inlet box at the bottom of the boiler, the center distances of air outlets are equal in the distance between an air inlet of the air inlet box and the tail end of the air inlet box, the bore diameter is increased gradually, fresh air blown in the air inlet box through an air blower can be evenly distributed to the fire grate bottom ventilating chamber through the air outlets under the condition that air pressure distribution is reduced gradually, and therefore balanced combustion of fired coal is effectively achieved, and the heat efficiency of the fired coal is improved.
Description
Technical field
The utility model relates to the inlet box in boiler technology field, particularly a kind of horizontal boiler.
Background technology
Horizontal coal-fired boiler has the servicing units such as air blast, to ensure the intake of boiler.To relatively large horizontal coal-fired boiler, because of grate area large, at transverse air-intake mouth, place is designed with inlet box, by the exhaust vent on inlet box, to draft chamber, fire grate bottom, supplied gas, on inlet box, having a plurality of spacing equates, the exhaust vent that aperture is equal, make the fresh air that air blast blasts can deliver to draft chamber, fire grate bottom, but because the area of fire grate is large, inlet box has certain degree of depth, and air blast is mounted in inlet box air inlet end, along on the depth direction of inlet box, air pressure gradually falls, cause just relatively diminishing gradually along the air quantity of sending into furnace grate ventilation chamber from each exhaust vent on the depth direction of inlet box, so the coal-fired amount of fresh air on the fire grate of air blast offside is relatively just few, combustion burning of coal on whole fire grate is with regard to different equilibrium.
Utility model content
(problem that utility model will solve)
The purpose of this utility model, is to provide and a kind ofly can be embodied as the balanced air-supply in draft chamber, fire grate bottom, thereby make the inlet box of the horizontal boiler of Fuel equalization burning.
(technical scheme of dealing with problems)
An inlet box for horizontal boiler, its structure is from inlet box air inlet, air blast installation end starts, to the distance of the inlet box end, have a plurality of toroidal exhaust vents towards draft chamber, fire grate bottom, it is characterized in that, the exhaust vent centre-to-centre spacing distributing equates, but aperture increases gradually.
The beneficial effects of the utility model are: the inlet box of described a kind of horizontal boiler, owing to being designed to from inlet box air inlet end to the distance of the inlet box end, each exhaust vent centre-to-centre spacing distributing equates, aperture increases gradually, make air blast be blown into the fresh air of inlet box, in the situation that gas pressure distribution is gradually fallen, can be assigned to by wind pushing hole equilibrium the draft chamber of fire grate bottom, thereby effectively realize coal-fired harmonious combustion, improve the thermal efficiency of coal.
Accompanying drawing explanation
Below in conjunction with requirement of the present utility model, with figure, further illustrate:
Fig. 1 is the position view of the inlet box of described a kind of horizontal boiler;
Fig. 2 is the inlet box structural representation of described a kind of horizontal boiler.
In figure, 1. inlet box, 2. exhaust vent, 3. inlet box air inlet, 4. burner hearth, 5. fire grate.
The specific embodiment
Fig. 1 is the position view of the inlet box of described a kind of horizontal boiler, and inlet box (1) has a plurality of exhaust vents (2) structure towards fire grate bottom.Fig. 2 is the inlet box structural representation of described a kind of horizontal boiler, and the exhaust vent of inlet box (2) opening is towards fire grate (5) bottom; Along in inlet box (1) end direction, from inlet box air inlet (3) end, start to inlet box end direction, the aperture size of each exhaust vent (2) increases gradually.
Claims (1)
1. an inlet box for horizontal boiler, from this inlet box air inlet, air blast installation end starts, to the distance of the inlet box end, have a plurality of toroidal exhaust vents towards draft chamber, fire grate bottom, it is characterized in that, each exhaust vent centre-to-centre spacing distributing equates, but aperture increases gradually.
