Abstract
A selective catalytic reduction and catalytic regeneration system includes: a main exhaust flow path; a reactor which is installed on the main exhaust flow path; a bypass exhaust flow path which branches off from the main exhaust flow path, and bypasses the reactor; an ammonia injection unit, which injects ammonia to the exhaust gas which is to flow into the reactor; a hydrolysis chamber, which produces ammonia to be supplied to the ammonia injection unit; a branch flow path, which branches off from the main exhaust flow path at a front side of the reactor; a recirculation flow path, which branches off from the main exhaust flow path at a rear side of the reactor, and merges with the branch flow path; and a multifunctional flow path, which connects the hydrolysis chamber with a point where the branch flow path and the recirculation flow path merge together.
