English to French Tech/Engineering Patents (in a patent) Method for controllinq ammonia content in cernent flue gas and cernent plant with controlled ammonia émission

Method for controlling an ammonia content in the exhaust gas (E) from a cernent manufacturing plant wherein the gaseous stream (G) produced during sintering a raw meal (M) to form a cernent clinker (C) is passed into a conditioning stage.

The method according to the invention advantageously also controls this ammonia, so that NOx réduction can be operated with more ammonia, because any ammonia slip is captured.

The Figures show cernent plants according to the invention that use the method for controlling ammonia according to the invention.

US 2009/0252665 A1 describes a control of ammonia slip from a non catalytic réduction of NOx by adding a catalytic oxidation of the ammonia in fossil fuel fired boilers
