2101318 9214969 PCTABS00015 Method for the production of hot drying gas by the burning of flowable, biological refuse in an incinerator (1) which comprises a vertical cyclone furnace (2), into which there is an injection of fuel (6) tangentially together with the primary combustion air, secondary combustion air (7) and tertiary combustion air (8) which is injected into a throat (5). In the bottom of the furnace there is provided a cooled, rotating ash scraper (11). The waste gas is conducted via a throat (5) to a secondary combustion chamber (3) in which an incineration of residuals takes place, and from which the drying gas (4) is removed. Combustion-retarding air (9) is injected into the hottest area of the cyclone furnace (2), so that sintering and the formation of slag is avoided.
