METHOD FOR REDUCING, BY RECOMBUSTION, OXIDES OF NITROGEN CONTAINED IN FUMES RESULTING FROM PRIMARY COMBUSTION PRODUCED IN AN OVEN, AND INSTALLATION FOR ITS IMPLEMENTATION

摘要

The invention relates to a method of reducing the nitrogen oxides contained in the fumes from a primary combustion, in an oven, by recombustion. It also relates to an installation for carrying out this process. BR/ The method according to the invention is characterized in that a secondary fuel is injected into the zone of recombustion of said furnace, according to at least two jets associated with relatively high and relatively low pressure, respectively. BR/ The invention finds application in the field of the purification of fumes, from a primary combustion.
