ABSTRACT:
A process for the removal of carbon-containing or nitrogen oxide-containing pollutants in low-dust flue gases by catalytic reduction, which is characterized in that a reducing agent is injected through nozzle(s) into the intermediate space of one stage of the economizer, said reducing agent is mixed with the low-dust flue gas in the tube bundles of the economizer, and the resultant reduction flue gas mixture passes catalyst layers located downstream of the economizer at a local velocity greater than 6.5 m/s.
