Abstract

PURPOSE: To prolong the life of a catalyst in a denitrifying reactor or the like operated at high dust concentration, in an exhaust gas-purifier for a coal-burning boiler, by locating a secondary dust-collector at the upperstream side of the denitrifier.
CONSTITUTION: A plurality of axial-flow straight-driving cyclones 9 are located in a flue 6 at the upperstream side of a denitrifying reactor 2, and a hopper 8 to collect dust separated by the cyclones 9 is located at the bottom of the flue 6. As a result, larger-particle size dust which has a substantial influence on the abrasion of a catalyst is preremoved by the secondary dust-collector composed of the arranged cyclones 9, so that the life of the catalyst is prolonged. Moreover, the height of the reactor 2 can be decreased by the arrangement of the secondary dust-collector. In adition, the fraction of electrically collected dust in the latter stage is not necessary, since the larger-particle size dust is preremoved.
