Erosion-resistant castables and SiC bricks for grate, furnace and flue zones of waste incinerators.
Waste-incinerator flue gas carries HCl, SO₂ and alkalis, combining corrosion with wear. The company supplies erosion- and wear-resistant, anti-clogging SiC castables and bricks for above-grate zones, secondary combustion chambers, WTE boiler inlets and ducts, extending lining life for waste-to-energy and hazardous-waste projects.

The incinerator furnace faces hot flue gas and alkaline fly ash; SiC bricks and alkali-resistant castables are combined.
View Problems & Solutions →The secondary combustion chamber sees 1100°C flue gas and alkali/chlorine attack; linings need alkali resistance and spall resistance.
View Problems & Solutions →Waste heat boiler inlet ducts suffer dust-laden gas erosion; wear linings combined with abrasion shields are used.
