Abstract

See full text

Nitrogen is removed from the waste gases from garbage incineration plant by the addition or generation of a reducing agent, e.g. ammonia, in the 2nd stage (2) of the 2 stage incineration process. The ammonia containing waste gases are cooled (4) and a reducing agent, for example more ammonia, is added (14) to them before they are passed over a catalyst (7) which reduces any remaining nitrogen oxide.
