Abstract

The method for introducing a treatment medium into the waste gas flow in combustion processes provides that a carrier medium is mixed with a treatment medium, wherein these media are brought to a pressure level necessary for atomization in a one-component nozzle prior to mixing. The quantitative proportion of treatment medium to carrier medium, which is adjustable as desired, is adjusted as a function of the NOx gas concentration in the treated gas flow or as a function of the gas quantity. It is substantial in this method that a plurality of atomizing nozzles are arranged in different planes, and that the flame development in the furnace is monitored by means of flame detectors. When the flame front reaches the lowest nozzle plane, the supply of treatment medium to these nozzles is blocked and the nozzles located above the latter, in which there is not yet a flame, are regulated with respect to the throughput of treatment medium as a function of the NOx gas concentration or the waste gas quantity.
As soon as the flame front forms again in the area of the lowest nozzles, treatment medium is again admitted to these atomizing nozzles. Carrier medium can also be admitted to the lower atomizing nozzles without treatment medium in order to cool the nozzles when the carrier medium is water.
