Abstract
The utility model provides an anti-abrasion structure for a water cooled wall and a screen-type heating surface wall-penetrating portion. The anti-abrasion structure prevents a water cooled wall from being abraded, and improves the running safety and reliability of a boiler. The anti-abrasion structure comprises a water cold wall, a screen type heating surface, a fire resistive material combining surface and a screen type heating surface wall-penetrating portion, and is characterized in that the fire resistive material combining surface is not convexly protruded outside a plane formed by a fire facing surface of the water cooled wall.
Description
(1) technical field
The utility model relates to the apparatus field of CFBB, is specially the abrasion-proof structure at a kind of 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, see Fig. 1, 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 there is a large amount of ash circulations in the circulating fluid bed boiler, a large amount of ash streams are along burner hearth wall decline all around, water-cooling wall 1 at this projecting surface easily weares and teares, and then the generation booster, have a strong impact on the security reliability of boiler operatiopn.
(3) summary of the invention
At the problems referred to above, the utility model provides the abrasion-proof structure at a kind of water-cooling wall and curtain wall place through walls, and 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: described refractory material faying face not evagination in the formed plane of described water-cooling wall side towards the fire.
It is further characterized in that: described curtain wall part through walls connects described refractory material faying face, and described curtain wall runs through described water-cooling wall by described curtain wall part through walls.
In the said structure of the present utility model, because evagination is not in the formed plane of described water-cooling wall side towards the fire for described 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 utility model.
(5) specific embodiment
See Fig. 2, the utility model comprises 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 by curtain wall part 4 through walls.
Claims (3)
1. the abrasion-proof structure at 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: described refractory material faying face not evagination in the formed plane of described water-cooling wall side towards the fire.
2. according to the abrasion-proof structure at described a kind of water-cooling wall of claim 1 and curtain wall place through walls, it is characterized in that: described curtain wall part through walls connects described refractory material faying face.
3. according to the abrasion-proof structure at described a kind of water-cooling wall of claim 2 and curtain wall place through walls, it is characterized in that: described curtain wall runs through described water-cooling wall by described curtain wall part through walls.
