The length to diameter ratios of rotary kilns can range ...

Rotary kiln incinerators can be operated in two modes, slagging and nonslagging. If the kiln is operated in the nonslagging mode, the ash temperature is kept below its fusion point. In the slagging mode, the ash temperature is allowed to rise above its fusion temperature, and the ash forms a liquid (or more accurately semiliquid) mass in the kiln. The type of kiln …

Extending refractory lifetime in rotary kilns for ...

Two philosophies coexist on how to run the rotary kiln: ashing or slagging modes. The effect on refractory disintegration differs because mean temperatures are 850–1150 °C in ashing mode and 1100–1400 °C in slagging mode .Consequently, the viscosity and corrosiveness of the combustion residue are not the same.
