Abstract

A unit for reducing pollutants (4) in the exhaust gases of internal combustion machines (2) composed of a fluidized bed combustor (10); an exhaust gas transfer line (11) suitable to supply the fluid bed combustor (10) with the exhaust gases coming from one or more internal combustion machines (2); and a fuel supply line (12) for the fluidized bed combustor (10). The fuel must be suitable to produce inside the fluidized bed combustor (10) a quantity of carbon and of ammonia suitable to react with the nitrogen oxides to cause reduction thereof to molecular nitrogen.
