  • 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.
