(JP8189626-A)      Waste material (16), esp. refuse, is thermally treated by being conveyed through the drum (30) of a rotary kiln (1) and subjected to a gaseous oxidant (26) which forms flames (28) with the volatile constituents (27) of the waste above the material. The heat thus generated leads to the release of further volatile constituents. The solids sepd. from the volatiles are recovered as refuse-coke, and the volatile constituents are recovered as a combustible gas. Also claimed is an appts. having a rotary kiln with a lance (18) for the oxidant projecting into it, whereby the lance has outlets for the oxidant along its entire length.    USE -   For the disposal of household and industrial refuse.    ADVANTAGE -   The waste material needs no pre-treatment. The volume of off-gas is reduced by up to 80 percent compared with that from conventional processes, and the overhead firing does not result in the carry-over of particulate matter associated with grate incinerators. The waste gas can be used as a fuel in other applications. The relatively low temperatures in the reaction chamber result in reduced thermal stresses of the materials of construction.
