Abstract

A reducing agent pyrolysis system for a selective catalytic reduction apparatus includes an elbow duct that is installed on an exhaust duct at a front end of a reactor, allows exhaust gas to flow into the elbow duct, and allows the inflow exhaust gas to be discharged toward the reactor. An inner pipe unit is disposed in the elbow duct, and allows a part of the exhaust gas to flow into and be discharged from the inner pipe unit. A heating device is installed in the inner pipe unit, and heats the exhaust gas flowing into the inner pipe unit. A nozzle is installed in the inner pipe unit, is disposed at a rear end of the heating device based on a flow of the exhaust gas, and injects a reducing agent into the inner pipe unit.
