<p>In a process for lowering the NOx content in combustion waste gases with the use of a reducing agent, the reducing agent has heretofore been added in all cases to the combustion gases downstream of the incineration. According to the invention, it is suggested in a fluidized-bed incineration to introduce the reducing agent into the fluidized bed. It is preferred, in this connection, to admix reducing agent to the utilized fuel and/or to the combustion air and/or to introduce the reducing agent directly into the incineration. Especially preferred reducing agents are NH3 or nitrogen-containing hydrocarbon compounds. Various additional versions of the feeding operation are possible.</p> |
