Generally, power plant boiler is composed of combustion chamber, water wall tube, superheater, economizer, preheater and steam drum, etc.

　　Power plant boiler is relatively large, and many tubes pass through boiler wall, so power plant boiler refractories should be selected carefully in order to prolong the service life of linings. Hitech Material provides a full set of refractory solution for power plant boiler with high-quality products and efficient quality services.

　　1. Boiler setting

　　Bottom supported heavy wall is generally built by fireclay bricks

　　Sectional supporting water cooled wall: fireclay refractory castable or plastic materials, lightweight refractory castables or insulation board;

　　Top supported water cooled wall: insulation board or lightweight refractory castables, refractory fibers or high-temperature glass wool.

　　2. Powdered coal burner

　　The burner linings which are affected by high temperature and erosion can use high alumina cement clay refractory castable or high-alumina plastic refractories.

　　3. Gasification chamber

　　Due to good heat conducting properties, silicon carbide monolithic refractory materials are used as linings in lower part of gasification chamber.

　　4. Refractory belt

　　high-alumina, mullite, corundum plastic refractories and refractory concrete
