FLUE GAS DENITROGENIZATION EQUIPMENT HAVING DEVICE FOR PREVENTING DRIFT OF BOILER

摘要

The present invention relates to an apparatus, for preventing drift of exhaust gas of denitrification equipment for boilers, which uniformly transfers exhaust gas to a catalyst layer by installing a guide vane in a bending unit of a duct and forming an air-hole in the guide vane, increases the combustion efficiency by installing a gas recirculation path in a horizontal unit of the duct, and introduces a predetermined amount of the exhaust gas flown into the gas recirculation path to a front-end of the catalyst layer by installing a perforated plate in a vertical unit of the gas recirculation path. The horizontal unit, bending unit, and vertical unit are continuously formed by being connected to one side of the boiler body. The gas recirculation path is installed on the bottom surface of the horizontal unit. A baffle plate is installed in the bending unit. Inside the vertical unit, the duct which has a denitrification catalyst is installed and the guide vane which is installed in front of the baffle plate of the bending unit of the duct. The perforated plate, which is installed inside the horizontal unit in the upper part of the gas recirculation path, is formed in the vertical unit.
