Rotary Kiln Zones
A process for the calcining of limestone or hydrated lime by thermal treatment thereof with hot gases in a rotary kiln through which the kiln atmosphere and the charge are countercurrently passed which kiln is fed with solid carbonaceous fuel is described The invention resides in introducing an oxygencontaining gas into a horizontal region across the rotary kiln defined by a point along
