STRUCTURE FOR ADJUSTING AIR VOLUME IN BYPASS FLUE AND FLUE-GAS DESULFURIZATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a structure for adjusting an air volume in a bypass flue, the structure being low in installation and maintenance cost and reducing a load imposed on a fan.;SOLUTION: The structure 1 adjusts a volume of an exhaust gas flowing in a bypass flue which connects the upstream and downstream of an absorption column provided in a flue-gas desulfurization device which makes the exhaust gas, which contains sulfur oxides emitted from a boiler, pass through the absorption column to remove sulfur. In this case, the structure 1 is provided with an upper closing plate material 23 which is provided so that the upper part of the bypass flue 22 may be closed.;COPYRIGHT: (C)2008,JPO&INPIT
