Wear-resistant and insulating refractory linings for CFB, pulverized coal and waste-to-energy boilers.
The key challenge in utility boiler linings is high-concentration solids erosion plus local over-temperature. The company supplies SiC wear-resistant and steel-fiber low-cement castables for CFB burner belts, cyclones and loop seals, plus lightweight insulating castables for PC boiler zones, recommending thickness and installation by boiler capacity and coal type.

CFB Boiler1 problems
CFB boilers circulate bed material at high velocity; wear-resistant castables in the dense phase and cyclone linings are the main maintenance focus.
View Problems & Solutions →Pulverized Coal Boiler1 problems
PC boilers expose burner zones to pulverized-coal impact and radiation; anchor design and spall resistance of linings are critical.

Application cases & castable solution practice
CFB Boiler Wearing Zone Abrasion-Resistant Reline
Dense-phase zones suffered severe particle abrasion. A steel-fibre reinforced SiC wear-resistant lining extended the continuous run from 8 to over 12 months.
