PROBLEM TO BE SOLVED: To provide a VOC combustion apparatus making VOC gas pollution-free. SOLUTION: A combustor 1 comprises an inner cylinder 6 and an outer cylinder 7 concentrical to each other. A mixing tube 4 is connected to the upper end of the inner cylinder, a diluting hole 8 is formed at the lower part of a peripheral wall, and an outlet 2 for combustion gas is formed at the lower end thereof. An air lead-in hole 9 to a space S between the walls is formed at the upper end of the outer cylinder, and the lower end thereof is fixed to the inner cylinder at its lower part. A large number of partition plates 10 are disposed zigzag or staggered in the space between the walls. The air including VOC is jetted together with a fuel in the inner cylinder through a mixing tube, burned, and the VOC is thermally decomposed. The air also flows from an air inlet into the space between the walls, heated by the inner cylinder while being meandered along the partition plates to decompose the VOC, and flows into the inner cylinder to control the temperature of the combustion gas. Since harmful components are not contained in the exhaust gas, there is no possibility of environmental pollution. COPYRIGHT: (C)2006,JPO&NCIPI
