FIELD: chemistry.SUBSTANCE: apparatus for processing raw material consisting of carbon-containing solid materials has a furnace, devices for feeding raw material, for moving the raw material, for feeding air into the top part of the furnace and undergrate blast, and for igniting the raw material with burners. There is a screw conveyor in the device for feeding raw material. The device for moving raw material is integrated with the screw conveyor in the device for feeding raw material and is made by mounting arched blades on turns of the screw conveyor. Blades are fitted in the screw conveyor for removing slag on the turns of the screw conveyor. In the device for undergrate blast there are parallel channels located on the sidewall of the furnace on ascending helical lines. The burners of the device for igniting raw material are mounted in a housing such that the next burner lies higher than the previous burner and lies therefrom at an angular distance of 90°.EFFECT: invention increases efficiency of processing raw material, reduces requirements for particle size and composition of raw material and improves reliability of the raw material processing apparatus.4 cl, 7 dwg |
