Abstract
In a process to reduce the nitrogen monoxide emissions generated during the combustion of solid fuels, before the combustion takes place, the entire amount of solid fuel is degasified inside a performance combustion area (2). At least part of the gas obtained during the degasification of the solid fuel is utilized as reduction gas in one or several reduction areas (3) that have been placed following the performance combustion area (2). In an installation for the implementation of the process the degasification device for solid fuel has been configured as a degasification section (5) for the continuous passage of fuel and has been arranged inside the combustion unit (1), within the flue gas current.
