PCT No. PCT/DK92/00039 Sec. 371 Date Aug. 12, 1993 Sec. 102(e) Date Aug. 12, 1993 PCT Filed Feb. 6, 1992 PCT Pub. No. WO92/14969 PCT Pub. Date Sep. 3, 1992.Method for producing hot drying gas by a burning flowable biological refuse in an incinerator which comprises a vertical cyclone furnace. Fuel together with primary combustion air is tangentially injected into the vertical cyclone furnace, and secondary combustion air and tertiary combustion air are injected into a throat. A cooled rotating ash scrapper is provided in the bottom of the vertical cyclone furnace and waste gas is conducted through the throat to a secondary combustion chamber in which an incineration of residuals takes place and from which a drying gas is removed. A combustion retarding gas is injected into the hottest area of the vertical cyclone furnace so that a sintering and the formation of slag is avoided. |
