Types of Wear-resistant Refractory Materials for Circulating Fluidized Bed Boilers

The operating temperature of the circulating fluidized bed boiler is high, and the temperature in the furnace changes frequently, resulting in thermal shock. At the same time, there are many high-temperature solid particles in the furnace, which continuously erode the heating surface, so it is necessary to lay wear-resistant refractory materials for maintenance. Types and characteristics of wear-resistant refractory materials for circulating fluidized bed boilers:

Introduction of wear-resistant refractory materials for circulating fluidized bed boilers

Wear-resistant refractory materials can be divided into fixed materials and non-fixed materials according to their delivery conditions and can be divided into wear-resistant refractory materials (including bricks, castables, plastics, and mortars); refractory materials (including bricks, castables, mortar); refractory insulation materials (including bricks, castables, and mortar).

typesetting material

(1) Wear-resistant refractory materials (dense refractory materials): silica-alumina bricks (silicon bricks, refractory clay bricks, high-alumina bricks), zirconium-silicon bricks, non-composite bricks (carbon bricks, silicon carbon bricks), magnesium-calcium-chrome bricks and Electrolytic magnesia product categories (magnesia bricks, chrome-magnesia bricks, chrome bricks, dolomite bricks).

(2) Insulation materials: refractory insulation bricks, insulation bricks, insulation blocks, ceramic fibers.

Unshaped material

Unshaped materials include castables, plastering materials, plastics, repair materials, spray gun materials, castables, vibrating materials, plastering materials, etc., and can be divided into powder materials, mud materials, and clay.
