Abstract

The utility model relates to a boiling furnace and in particular relates to a boiling furnace with residue collection walls. The boiling furnace with the residue collection walls comprises a combustion chamber, a dust chamber, a fire wall and a residue outlet, wherein the two crossed residue collection walls are arranged in the dust chamber and are both slope walls; the crossed line of the two residue collection walls falls into a vertical central surface in a length direction of the dust chamber; the length of each residue collection wall is the same as that of the dust chamber; the two residue collection walls have the same slope degree. According to the boiling furnace with the residue collection walls, ash residues are collected and fall in positions, close to the residue outlet, on the two sides of the dust chamber, so that the ash residues can be conveniently removed, the efficiency is improved and the practicality is high.

Description

A kind of fluidized bed furnace with poly-slag wall

Technical field

The utility model relates to a kind of fluidized bed furnace, relates in particular to a kind of fluidized bed furnace with poly-slag wall.

Background technology

In fluidized bed furnace, coal is broken after crusher machine becomes the coal grain below 0 ~ 8mm and adds combustion chamber (burner hearth).Bottom, combustion chamber is furnished with perforated distributor, below air distribution plate, be connected with air compartment, air blast by air compartment the blast cap on air distribution plate air is sent into burner hearth, blow coal grain and burn red yellow ground and make it in fluidized state, thereby produce heat, in fluidized bed furnace after complete combustion of fuel, the lime-ash of after-flame divides and becomes scattered about each corner of falling dust room, and lime-ash is not easy cleaned, As time goes on cumulative, if do not cleared up timely and effectively, will affect the combustibility of fluidized bed furnace.

Summary of the invention

The utility model overcomes above-mentioned the deficiencies in the prior art, provides a kind of and avoids lime-ash accumulation in the middle of burner hearth, lime-ash is fallen within to falling dust room both sides for concentrated minute near the fluidized bed furnace of the poly-slag wall of band of slag notch position.

The technical solution of the utility model is achieved in that a kind of fluidized bed furnace with poly-slag wall, comprises combustion chamber, falling dust room, firebreak and slag notch, is provided with the poly-slag wall in crossing Ju Zhaqiang， two sides, two sides and is gradient wall in described falling dust room.

Described in two, the poly-crossing intersection of slag wall falls within the vertical median plane on falling dust room's length direction.

The length of described poly-slag wall and falling dust room equal in length.

Described in two, the gradient of poly-slag wall equates.

The height of described poly-slag wall is not higher than 1/2nd of furnace wall height.

The technique effect that the technical solution of the utility model produces is as follows: in above-mentioned fluidized bed furnace, be provided with the two poly-slag walls that intersect, two poly-slag walls all have certain slope, lime-ash is concentrated to divide to fall within falling dust room both sides near the place of slag notch under the effect of poly-slag wall, by simply drawing slag instrument, just can clear up away, when this has just been avoided furnace width larger, divide the lime-ash that becomes scattered about each corner of falling dust room to be not easy cleaned problem, alleviated working strength, and this convenience simple in structure, be easy to realize, practical.

Accompanying drawing explanation

Fig. 1 is one of structural representation of the present utility model.

Fig. 2 is two of structural representation of the present utility model.

In figure, be labeled as: 1, falling dust room; 2, firebreak; 3, slag notch; 4, poly-slag wall; 5, combustion chamber; 6, furnace wall.

The specific embodiment

A kind of fluidized bed furnace with poly-slag wall, as shown in Figure 1, 2, comprise falling dust room 1, combustion chamber 5, firebreak 2, furnace wall 6 and slag notch 3, in described falling dust room, be provided with two and intersect poly-slag wall 4, described in two, poly-slag wall is gradient wall, the gradient of two poly-slag walls is identical, the length (being the horizontal range from firebreak to the furnace wall nearest apart from firebreak) that the length of two poly-slag walls is falling dust room, two poly-slag walls intersect at an intersecting lens, and this intersecting lens falls within the vertical median plane on falling dust room's length direction.

In Fig. 2, become the conny of certain particle size to fall in stove by coal sliding tube, the air-flow upwards being flowed holds up, in certain altitude range, make upper and lower tumbling motion, in stove with the state conflagration of class pseudo boiling, the cinder of after-flame falls into falling dust room, is gathered slag wall to be separately deposited in both sides near the position of slag notch, opens fire door and just can clear up lime-ash easily.

Described poly-slag wall height is about 1/3rd of furnace wall height.

In addition, the height of described poly-slag wall only otherwise higher than half of furnace wall height, all can realize good effect of the present utility model.
