     Vortex function as feeds heater, gas & solids separator, material transfer, is the place where some physical and chemical reactions take part. The vortex requires refractory performs good alkaline , corrosion and erosion resistance.

         Usually, inlet is combined by vortex and decomposing furnace, mainly worked as pre-heater and pre-dissociation reactor. As the dissociation processing of raw material releases heat, usually, the temperature of inlet is 800-900 ℃. We need refractory with good thermal resistance, corrosion and erosion resistance, and chloride resistance.

 Security Zone



        The temperature in security zone usually is 1200-1400 ℃, it need refractory with good properties of thermal shock, high temperature, chemical and corrosion resistance.


 Burning Zone



         Burning zone can reaches a temperature of 1450 ℃, it requires refractory with good coating adherence, which is the key property to a success lining material, and high refractoriness, chemical resistance and corrosion resistance.

         Outlet is a place to cooler the chamotte, dealing with waste, etc. The temperature there can reach 900-1200 ℃. Refractory for outlet should be thermal shock stable and corrosion resistant.

        The cooling air can be reused, and the part with highest temperature transfers to the inlet via TAD, then support heating there. Refractory for TAD should be high-strength, corrosion and erosion resistance.
