Reaction Bonded Silicon Carbide burner tubes for industrial furnace

Product detail

Reaction-bonded silicon carbide (SiSiC) exhibits outstanding wear resistance, impact resistance, and chemical performance, with a usage temperature of up to 1250 degrees Celsius. It successfully addresses the thermal shock sensitivity issue observed in tubes made from mullite and other ceramic materials. SiSiC's mechanical properties at high temperatures surpass those of heat-resistant alloys, particularly in terms of strength, creep stress, and thermal oxidation, allowing for a net heat flux of up to 110 Btu/hr per square inch (50 kW/m2). These tubes can be utilized in furnaces with zone temperatures reaching 1250 degrees Celsius. In comparison, alloy tubes are typically used for heat fluxes of 60 Btu/hr per square inch (27 kW/m2) and lower, with a maximum furnace usage temperature of approximately 1100 degrees Celsius. Reaction-bonded silicon carbide can be shaped into various forms, including cone and sleeve shapes, as well as more complex engineered parts designed for equipment involved in raw material processing. This makes it suitable for applications in large ceramic combustion tubes and nozzles.
