SELECTIVE CATALYTIC REDUCTION SYSTEM

WIPO Patent Application WO/2016/105153

A1

A selective catalytic reduction system according to an embodiment of the present invention comprises: a main exhaust passage through which exhaust gas of an exhaust gas discharging source is transferred; a reactor which is installed on the main exhaust passage, the reactor comprising a catalyst for reducing nitrogen oxide contained in the exhaust gas; a reducing agent injection unit which is installed on the main exhaust passage to inject a reducing agent to the exhaust gas that is transferred to the reactor; a decomposition chamber which receives and decomposes a reducing agent precursor to thereby prepare a reducing agent to be supplied to the reducing agent injection unit; a heat flux supply source which supplies, to the decomposition chamber, heat energy necessary for decomposing the reducing agent precursor; a heat flux supply flow passage which connects the heat flux supply source and the decomposition chamber; and a heat flux bypass flow passage which is branched from the heat flux supply flow passage and controls a heat flux supplied to the decomposition chamber.
