摘要：
For selective reduction of the NO-content in exhaust gases from a kiln plant, a method is described according to which a mixture of ammonia and water is introduced into the exhaust gases. According to this method the ammonia and water is mixed just prior to being sprayed into the kiln plant by the ammonia being dosed into a preferably even stream of water. Hence an inexpensive and efficient removal of the NO-content in the exhaust gases is obtained.
