Abstract

See full text

The method for introducing a treatment medium into the waste gas flow in combustion processes provides that a carrier medium be mixed with a treatment medium, wherein these media are brought to a pressure level necessary for the 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 NO.sub.x gas concentration in the treated gas flow or as a function of the waste gas quantity. The atomization pressure is either predetermined as a fixed value corresponding to the nozzle configuration or adjusted as a function of the waste gas quantity. The atomization pressure can also possibly be regulated as a function of the evaporator load. Water serves as carrier medium, while ammonia, sal ammoniac, urea or calcium cyanamide is used as treatment medium.
