Device for feeding alternative fuels into a revolving tubular furnace and method for feeding these alternative fuels and/or waste products

摘要

In a device for charging lumpy alternative fuels and/or waste products into a rotary kiln at a location situated between the charging end and the discharging end of the rotary kiln, wherein a closable opening is provided in the jacket of the rotary kiln, the opening carries an inwardly opening flap which is spring-loaded in the sense of closing, and a lifting device such as, e.g., a fork adjoins the opening in a substantially radial direction, from which lifting device the fuels or waste products to be charged are dischargeable into the rotary kiln under the action of gravity while overcoming the closing force of the flap.
