Definitions
- the present invention relates to protection against corrosion and erosion of the combustion chambers of boilers. This invention applies more particularly, without being limited to this application, to the protection of the combustion chambers of boilers which equip incineration plants with household and industrial waste.
- the object of this invention is to provide an improvement in the fixing of these prefabricated refractory parts, in order to avoid their corrosion.
- this invention relates to a method for protecting and fixing prefabricated refractory parts, fixed to the walls of the combustion chambers of boilers by means of hooking elements, characterized in that it consists in protecting the element of attachment by a layer of refractory product. According to the invention, it is possible to provide the connection between the refractory part and the corresponding attachment element using the same refractory product.
- said refractory product can be insulating or heat conducting, with chemical, hydraulic or other binder, and it may or may not contain silicon carbide. depending on whether it is conductive or insulating respectively.
- the fastening element and its housing in the refractory piece are communicated to any suitable shape allowing the fixing to be improved.
- the attachment element 10 and its housing in the refractory part 16 have walls with parallel or cylindrical faces, the layer of bonding product 14 ensuring the holding by simple bonding.
- the fastening element 10 ⁇ is inclined or has an upwardly inclined face, in "coat hangers", so as to improve the resistance by the action of gravity.
- a hooking element 10 ⁇ is used which has a larger section at its end than at its base, and which is positioned in a housing of the refractory piece 16 which has a corresponding shape.
- the layer 14 of bonding product ensures, after drying, a mechanical keying, which clearly improves the resistance. It is then possible to place refractory pieces on the ceiling.
- all the free spaces between the different refractory pieces 16 must be carefully filled with the bonding product, in order to avoid gas infiltration and the pumping effects during temperature variations.
- the hooking elements 10 can be fixed either on the fins 12 (Figure 4), or on the tubes 18 of the tubular panels ( Figure 5).
- the refractory pieces 16 can cover a tube 18 (FIG. 5) or several tubes (FIG. 6), the connection points then being either in line with the fin 12, or in line with the tube 18.
- the seal between the refractory pieces 16 can be improved by creating baffles 20 ( Figure 7).
- the housing of the refractory piece which receives the hooking element, such as 10 can be blind or through. If it is through, the filling of said housing with the bonding product is facilitated, but the protection of the refractory piece 16 is weak, whereas on the contrary, if it is blind, the filling of the housing is more difficult, but protection is better.
- the refractory pieces may include one or more housings to receive the fastening elements.
