CATALYST COMBUSTOR

摘要

PURPOSE:To permit the treatment of gas of a large capacity by a method where in the concentration of stress due to thermal strain and the like in combustion catalyst is reduced, the concentration of hydraulic pressure on one part of the combustion catalyst near a rear stage is prevented and the diameter of a catalyst combustion chamber is increased without spoiling the catalytic performance of reducing the generation of NOx and the like while preventing deformation and/or cracking even under an using condition at a high temperature. CONSTITUTION:In a catalyst combustor provided with a plurality of combustion catalyst bodies 5 having a multitude of penetrating holes in the direction of a flow passage in a tubular member 3 forming the flow passage in parallel along the direction of the flow passage, the combustion catalyst bodies 5 are fitted into the tubular members 3 loosely while the tubular members 3 are provided with retaining members S precluding the movement of the combustion catalyst bodies 5 in the direction of the flow passage by abutting against the end faces of the flow passage direction of the combustion catalyst bodies 5.
