Abstract
The utility model relates to a combustion chamber structure which comprises a combustion chamber, the inner wall of the combustion chamber is coated with a coating which is chosen from a zirconia composite coating, an alumina coating and an alumina composite coating. The combustion chamber structure has the beneficial effects that the inner wall of the combustion chamber is coated with the coating, and the coating is strong in corrosion resistance, high temperature resistant, stable in chemical properties, wear resistant and erosion resistant, and effectively prevents the combustion chamber from being corroded by harmful toxic gas.
Description
Technical field
The utility model relates to a kind of fluidized-bed combustion boiler, particularly relates to a kind of chamber structure.
Background technology
The main material that fluid bed solid waste burning stove burns is the synthetic leather rectification residue, belongs to dangerous solid useless, burns the gas residence time that produces and requires greater than 2s.And the material of normal stream fluidized-bed incineration is a coal, and the burner hearth gas residence time is generally 1.5s, and flue gas can not get thorough processing.For the poisonous and harmful element that destroys by fire more completely in the flue gas has increased secondary combustion chamber again before flue gas enters convection heating surface, and be equipped with diesel fuel burner and be not less than 1100 degree with the temperature that guarantees secondary furnace.But these waste gas and harmful gases generally all are corrosive, and certain corrosion can be arranged the inwall of combustion chamber.
The utility model content
For addressing the above problem, the utility model provides a kind of chamber structure that can effectively prevent the combustion chamber inner wall corrosion.
Chamber structure of the present utility model comprises the combustion chamber, and inwall scribbles coating in the combustion chamber, and this coating is selected a kind of in zircite composite coating, aluminum oxide coating layer, aluminium oxide composite coating.
Chamber structure of the present utility model, the thickness of described coating are 0.5-1mm.
The beneficial effect of the utility model chamber structure is: the utility model has increased coating on the inwall of combustion chamber, and coating is corrosion-resistant strong, high temperature resistant, stable chemical performance, and wear-resisting, erosive wear resistance has effectively prevented the corrosion of harmfulness toxic gas.
Description of drawings
Fig. 1 is the structural representation of the utility model chamber structure.
The specific embodiment
Below in conjunction with Figure of description a kind of chamber structure of the utility model is described further.
Referring to Fig. 1, a kind of chamber structure of the present utility model comprises combustion chamber 1, and 1 inwall scribbles coating 2 in the combustion chamber, and this coating 2 is a zircite composite coating.
Chamber structure of the present utility model, the thickness of described coating are 1mm.
The utility model has increased coating on the inwall of combustion chamber, coating is corrosion-resistant strong, high temperature resistant, stable chemical performance, and wear-resisting, erosive wear resistance has effectively prevented the corrosion of harmfulness toxic gas.
Above embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
Claims (2)
1. a chamber structure comprises the combustion chamber, it is characterized in that: inwall scribbles coating in described combustion chamber, and this coating is selected a kind of in zircite composite coating, aluminum oxide coating layer, aluminium oxide composite coating.
2. chamber structure according to claim 1 is characterized in that: the thickness of described coating is 0.5-1mm.
