Process and furnace for burning refuse

A method of and an apparatus for the thermal degradation of refuse, garbage and other waste material in which the waste material stream is reacted with air or oxygen in a reaction chamber for pyrolysis, destructive distillation or incineration of the waste material. The released thermal energy, spatial temperature distribution or outlet gas temperature is measured and used to control a feeder which supplies particles of a supplemental fuel, itself recovered from a waste material separate from the waste material stream, to the reaction chamber.

Method of and apparatus for thermal degradation of waste

A rotary kiln with primary air feed at the end wall of the rotary kiln is distinguished by the feature that at least two primary air nozzles are oriented relative to each other and to the fuel bed so that two oppositely directed vortices are generated within the rotary kiln, the axes of rotation of said vortices extending substantially parallel to the axis of the rotary kiln and said vortices rotating about said axes of rotation so as to promote the thermal convection-induced motion of the combustion gases.

Rotary kiln

A pyrolysis reactor is coupled with an incinerator plant in the pyrolysis apparatus of our invention. In one variant the pyrolysis gas arrives directly in the furnace of the incinerator plant. In another variant the pyrolysis gas is burned in an additional separate combustion chamber and the flue gas arising from its combustion is fed into the flue gas duct of the incinerator. Because of that the units required in an economically self sufficient pyrolysis plant for purifying and using the pyrolysis gas and for the exhaust gas cleaning are made more economical. A process for consuming waste according to our invention is also described.
