Preparation method of ceramic fiber porous burning medium
The invention relates to a preparation method of a ceramic fiber porous burning medium. Stable ceramic fiber turbid liquid is subjected to suction filtration to obtain ceramic fiber paper of a self-supporting structure, the ceramic fiber paper is laminated to obtain layered fiber felt with certain thickness, a ceramic phase matrix is prepared on the ceramic fiber felt, connecting ceramic fibers are obtained, and the ceramic fiber porous burning medium material is obtained. The porosity of the ceramic fiber porous burning medium material is high and can reach about 90%, and a low air pressure difference is generated when reactant gas passes. The ceramic fiber porous burning medium is small and exquisite in structure and flexible in shape, and can be conveniently used in a stove. Due to the fact that the medium material is of a fiber skeleton structure, the specific surface area of the medium is greatly reduced, the acoustic shock phenomenon of fuel gas in the reaction process can be remarkably avoided, and the service life of the material is prolonged. Excellent high-temperature strength and stability are achieved, the medium cannot be oxidized in the gas environment, and the long service life is achieved.
