Abstract

The method of supplying a treating agent to the exhaust gas stream in combustion processes provides for mixing a carrier medium with a treating agent, these media being brought before mixing to a pressure level necessary for atomization in a single-component nozzle. The ratio of the quantities of treating agent and carrier medium is infinitely adjustable and is adjusted as a function of the NOx gas concentration in the treated gas stream or as a function of the gas rate. The essential fact in this process is that a plurality of atomization nozzles are arranged in different planes and that the flame evolution in the firing space is monitored by flame detectors. When the flame front reaches the lowest nozzle plane, the feed of treating agent to these nozzles is shut off and the nozzles which are located above and in which there are as yet no flames, are controlled with respect to the throughput of treating agent as a function of the NOx gas concentration or of the exhaust gas rate. As soon as the flame front forms again in the region of the lowest nozzles, these atomization nozzles are fed again with treating agent. Even without treating agent, the lower atomization nozzles can be fed with carrier medium in order to cool the nozzles, if the carrier medium is water. <IMAGE>
