A rotary kiln device for incinerating combustible materials such as municipal and commercial waste materials. The kiln is a co-current gas-material flow apparatus. The kiln is divided by means of a dam into a drying zone and a combustible zone. Waste material is retained within the drying zone sufficiently long so that that moisture contained in the material is driven off. Air for combustion is supplied directly to the combustion zone, bypassing the drying zone so that self-sustaining combustion may take place.

A method for incinerating combustible material comprising the steps of providing an elongated vessel mounted on an incline and having an upper inlet end and a lower outlet end; dividing the vessel into a drying zone and a combustion zone by providing a dam inside the vessel; rotating the vessel about its own axis; supplying material to be incinerated to the drying zone through the upper inlet end of the vessel; supplying hot drying gases to the drying zone for drying the material to be incinerated; discharging the material from the drying zone by displacement over the dam into the combustion zone; supplying air for combustion directly to the combustion zone by-passing the drying zone through a conduit which extends through the drying zone for incinerating the dried material in the combustion zone; discharging through the lower outlet end of the vessel ash from the incineration of the material and discharging spent drying and combustion gases from the lower outlet end of the vessel whereby the flow of gases through the vessel is co-current to the flow of material from the inlet of the vessel to the outlet of the vessel.
