REDUCTION AGENT Pyrolysis System for Selection for Selective Catalytic Reduction

摘要

The present disclosure relates to a reducing agent pyrolysis system for a selective catalytic reduction apparatus. The reducing agent pyrolysis system for a selective catalytic reduction apparatus according to the present disclosure includes: an elbow duct 10 which is installed on an exhaust duct at a front end of a reactor, allows exhaust gas to flow into the elbow duct 10, and allows the inflow exhaust gas to be discharged toward the reactor; an inner pipe unit 20 which is disposed in the elbow duct 10, and allows a part of the exhaust gas to flow into and be discharged from the inner pipe unit 20; a heating device 60 which is installed in the inner pipe unit 20, and heats the exhaust gas flowing into the inner pipe unit 20; and a nozzle 70 which is installed in the inner pipe unit 20, and disposed at a rear end of the heating device 60 based on a flow of the exhaust gas, and injects a reducing agent into the inner pipe unit 20.
