<P>PROBLEM TO BE SOLVED: To provide a combustion furnace for burning plant-based regenerative fuel, configured to prevent deterioration of a component when the fuel is supplied, thereby improving durability. <P>SOLUTION: The combustion furnace 1 includes: a cylindrical combustion chamber 2; a water jacket 3 formed to surround the outside of the combustion chamber 2; and a cylindrical upper air chamber 4 arranged outside the water jacket 3. On a combustion chamber wall 21 and an upper casing 31, a plurality of air supply tubes 71, 72, 73 are fixed therethrough, as secondary air supply parts for guiding combustion air in the upper air chamber 4 to the combustion chamber 2. In the bottom surface of the combustion chamber 2, through holes 61, 61, ... as primary air supply parts and a disk-like bottom plate 6 having a receiving part 62 of fuel F are arranged. In the combustion chamber wall 21, a fuel supply port 91a of a screw conveyor 9 is formed for supplying the fuel F to the combustion chamber 2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
