Summary of the invention
The utility model is in order to solve the haydite fritting furnace complex structure that exists in the prior art, problem such as ceramisite sintered quality is inhomogeneous, the cost height and a kind of box coal ash haydite fritting furnace is provided.
The utility model is realized by following technical scheme, a kind of box coal ash haydite fritting furnace, comprise the body of heater that has fire door, the body of heater bottom is provided with inlet plenum, the inlet plenum top is provided with some dividing plates that are vertically arranged in parallel, on the upper wall of the inlet plenum between the adjacent dividing plate, be provided with at least one air passing hole, put on the shelf at adjacent dividing plate and to be provided with some refractory brick, left air cleft between the adjacent refractory brick, some refractory brick constitute the fire grate that supports haydite, and the fire grate top is the combustion chamber, and top, combustion chamber is exhaust chamber, be provided with air inlet pipe in inlet plenum, air inlet pipe is provided with steam vent.
Compared with prior art, the pressure combustion mode of bottom air inlet has at first been adopted in design of the present utility model, makes the haydite burning more complete.Air inlet pipe vertically is provided with the plurality of rows pore makes air inlet send into inlet plenum equably; Upper wall and some dividing plates by inlet plenum make the some relatively independent air chambers excessively of formation between fire grate and the inlet plenum, and the gas that makes into can pass fire grate uniformly and enter the combustion chamber.Comprehensive, the utility model is simple in structure, good airproof performance, and burning velocity is fast, and cost is low, and pressure combustion is simple to operate, the more important thing is uniform in quality, is suitable for the haydite production of various flyash.
