Abstract
The invention provides an improved anti-abrasion structure at the wall-through place of a water-cooling wall and a screen-type heating surface. The improved anti-abrasion structure can ensure no abrasion of the water-cooling wall and improve the safety and the reliability of the operation of a boiler. The improved anti-abrasion structure comprises the water-cooling wall, the screen-type heating surface, a refractory material bonding surface and a wall-through part of the screen-type heating surface, and the improved anti-abrasion structure is characterized in that the refractory material bonding surface is not protrudent on a plane formed by a fire-facing surface of the water-cooling wall.
Description
(1) technical field
The present invention relates to the apparatus field of CFBB, be specially the abrasion-proof structure at a kind of improved water-cooling wall and curtain wall place through walls.
(2) background technology
Existing CFBB; The structure at its water-cooling wall and curtain wall place through walls is seen Fig. 1, and it comprises water-cooling wall 1, curtain wall 2, refractory material faying face 3, curtain wall part 4 through walls; Refractory material faying face 3 protrudes from the formed plane of water-cooling wall 1 side towards the fire; Owing to existing a large amount of ashes to circulate in the circulating fluid bed boiler, ash stream is along burner hearth wall decline all around, water-cooling wall 1 easy wearing and tearing of this projecting surface in a large number; And then the generation booster, have a strong impact on the security reliability of boiler operatiopn.
(3) summary of the invention
To the problems referred to above, the invention provides the abrasion-proof structure at a kind of water-cooling wall and curtain wall place through walls, it guarantees that water-cooling wall is not worn, and improves the security reliability of boiler operatiopn.
Its technical scheme is such: it comprises water-cooling wall, curtain wall, refractory material faying face, curtain wall part through walls, it is characterized in that: said refractory material faying face not evagination in the formed plane of said water-cooling wall side towards the fire.
It is further characterized in that: said curtain wall part through walls connects said refractory material faying face, and said curtain wall runs through said water-cooling wall through said curtain wall part through walls.
In the said structure of the present invention; Because evagination is not in the formed plane of said water-cooling wall side towards the fire for said refractory material faying face, a large amount of ashes flow when wall descends around burner hearth, can not cause wearing and tearing to water-cooling wall again; It guarantees that water-cooling wall is not worn, and improves the security reliability of boiler operatiopn.
(4) description of drawings
Fig. 1 is the structural representation at existing water-cooling wall and curtain wall place through walls;
Fig. 2 is a structural representation of the present invention.
(5) specific embodiment
See Fig. 2, the present invention includes water-cooling wall 1, curtain wall 2, refractory material faying face 3, curtain wall part 4 through walls, refractory material faying face 3 not evagination in the formed plane 5 of the side towards the fire of water-cooling wall 1.Curtain wall part 4 through walls connects refractory material faying face 3, and curtain wall 2 runs through water-cooling wall 1 through curtain wall part 4 through walls.
Claims (3)
1. the abrasion-proof structure at improved water-cooling wall and curtain wall place through walls; It comprises water-cooling wall, curtain wall, refractory material faying face, curtain wall part through walls, it is characterized in that: said refractory material faying face not evagination in the formed plane of the side towards the fire of said water-cooling wall.
2. according to the abrasion-proof structure at said a kind of improved water-cooling wall of claim 1 and curtain wall place through walls, it is characterized in that: said curtain wall part through walls connects said refractory material faying face.
3. according to the abrasion-proof structure at said a kind of improved water-cooling wall of claim 2 and curtain wall place through walls, it is characterized in that: said curtain wall runs through said water-cooling wall through said curtain wall part through walls.
