Disclosed is a rotary kiln that can be used efficiently in drying, dry distillation and incineration of various garbage and industrial wastes.The rotary kiln comprises a cylindrical furnace body (10) disposed to incline at a small angle from the horizontal plane, a cylindrical contact heater (20) supported in the furnace body (10), a rotation drive means (30) that drives the furnace body (10) and the contact heater (20) to rotate, a waste charging port (61), a processed material discharging port (18), a combustion gas supply means (40) that supplies a combustion gas into the cylindrical contact heater (20) and a combustion gas introducing means (50) that guides the combustion gas through the contact heater (20) from a distal end to a proximate end thereof, and then guides the combustion gas through a space (S) between the contact heater (20) and the furnace body (10) from the proximate end to the distal end, thereby to charge.
