REDUCING AGENT DOSING SYSTEM OF SELECTIVE CATALYTIC REDUCTION SYSTEM

摘要

The present invention relates to a reducing agent pyrolysis system of a selective catalytic reduction system. The reducing agent pyrolysis system of the selective catalytic reduction system according to the present invention includes: an elbow duct (10) installed in an exhaust duct at a front end of a reactor to introduce exhaust gas and to discharge the introduced exhaust gas to the reactor; an inner pipe unit (20) provided inside the elbow duct (10) to introduce and discharge a portion of the exhaust gas; a heating device (60) installed in the inner pipe unit (20) to heat the exhaust gas introduced into the inner pipe unit (20); and a nozzle (70) installed in the inner pipe unit (20) and provided at a rear end of the heating device (60) based on the flow of the exhaust gas to project a reduction agent into the inner pipe unit (20).
