The counter current rotary kiln has waste entry in in the front and flue gas exit (also) in the front of the kiln. Slagging is the high temperature ash (with a lack of oxygen) which has carbon and so it has a sticky character and difficult to handle. Photo Slag or ash of a co-current rotary kiln.
Read MoreThe 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.
