SELECTIVE CATALYTIC REDUCTION SYSTEM AND POWER APPARATUS COMPRISING SAME

Document Type and Number:

WIPO Patent Application WO/2016/108616

Kind Code:

A1

Abstract:

A selective catalytic reduction system according to an embodiment of the present invention comprises: a reactor installed on a main exhaust flow path in the rear of a turbocharger installed on the main exhaust flow path; a reducing agent injection part, installed on the main exhaust flow path, for injecting a reducing agent to an exhaust gas moving toward the reactor; a decomposition chamber which is supplied with a reducing agent precursor and decomposes the same to generate the reducing agent to be supplied to the reducing agent injection part; a bifurcation channel which is bifurcated from a turbocharger bypass flow path, which is bifurcated from the main exhaust flow path and bypasses the turbocharger and is again merged into the main exhaust flow path, and connected to the decomposition chamber; an external air supply flow path for supplying external air to the decomposition chamber; a blower, installed on the external air supply flow path, for drawing in the external air; and a heating device, installed on the external air supply flow path, for heating the external air drawn in by the blower.
