PURPOSE: A drying furnace is provided to improve drying efficiency by drying sludge at the outside and inside of a drying cylinder, simultaneously. CONSTITUTION: In a drying furnace, a first support body(40) is installed at one side of a drying cylinder having a feed screw. And, the first support body supplies high-temperature air to the inside of the feed screw, and discharges steam in a duct of the drying cylinder to the outside. A second support body is installed at the other side of the drying cylinder, and moves the high-temperature air to the duct of the drying cylinder. A sealing cover(60) is inserted into the outer surfaces of the support bodies, and supports a rotary shaft(23) of the feed screw. And, the sealing cover couples a drum(22) of the feed screw to the support bodies airtightly.
