METHOD FOR REDUCING NITROGEN OXIDES IN THE EXHAUST GAS OF AN ENTRAINED-FLOW TREATMENT PLANT, AND ENTRAINED-FLOW TREATMENT PLANT

摘要

Disclosed is a method for reducing nitrogen oxides in the exhaust gas of an entrained-flow treatment plant in which a material is subjected to a thermal treatment; at least some of the thermal energy used for said treatment is supplied by a hot gas generator (3). The disclosed method is characterized in that a reducing agent is admixed to the hot gas from the hot gas generator (3) before the temperature of the hot gas drops to 700°C or less, preferably 850°C or less.
