Rotary waste incinerators usually consist of a rotating cylinder and a secondary combustion chamber.The rotary device is used to evaporate the waste being thrown in and make the solid residue environmentally sound.Solid, sludge, slurry, liquids and packaging waste all can be incinerated in the rotary device. Rotary incinerators can be further classified as ash-type or slag-type according to their operating temperature. Residues from rotation can include raw solids such as ash, slag, frozen slag and non-ferrous metals and glass. The gas produced in the rotary kiln and some fly ash are transported to the SCC, where the final thermal damage to the waste is achieved by adding oxygen to the system or by using an auxiliary burner.
The subarea of refractory for waste incinerators is used to minimize the cost of refractory materials. Lite recommended Silicon carbide bricks and silicon carbide castable are used for for the highest temperature part.
70% Al2O3 high alumina bricks and high alumina plastic refractory are used for intermediate temperature part.Clay bricks are used for for lower temperature part.Due to the many subareas in the waste incinerators,customer had better provide the design and operating specification to ensure the most economical refractory products installed in each area.
