Abstract

A fritting furnace used for preparing ceramic particles with fly-ash is featured as arranging top flame-passing hole and bottom flame-passing hole on isolation wall between left and right combustion chambers in furnace body, passing top gate plate in isolation wall above top flame-passing hole and passing bottom gate plate in isolation wall below bottom flame-passing hole, erecting left fire grate at middle of left combustion chamber (CC) and right fire grate at middle of right CC, arranging smoke-passing duct above right CC and setting smoke-passing hole between said smoke-passing duct and CC.

Description

technical field [0001] The invention relates to a sintering furnace, in particular to a fly ash ceramsite sintering open hearth furnace. Background technique [0002] Ceramsite is a kind of man-made lightweight aggregate, which is a hard shell, with a layer of water-proof and air-retaining glaze layer on the surface, and microporous and porous ceramsite particles inside. It uses shale, sea mud clay, mudstone, fly ash, coal gangue, etc. as raw materials, which are processed into spheres and then inflated to shape. It has the characteristics of small bulk density, high strength, good thermal insulation and sound insulation performance, earthquake resistance, good durability, and strong construction adaptability. Widely used in various construction fields. Fly ash sintered ceramsite uses fly ash as the main raw material to form a new light, high-strength and multi-functional material through granulation, pelletization and high-temperature firing at 1000°C. my country is a co...
