There is described a plant for reducing bitumen fumes comprising: a) an intake system for drawing in the bitumen fumes and mixing those fumes with external air (ambient air) to produce an admixture of external air/bitumen fumes; b) a system for introducing this admixture into a boiler (9) as a primary supply (primary air) so as to maintain the admixture in the boiler (9) for at least two seconds; c) a sensor which is for measuring oxygen and which is positioned in the discharge chimney of the burnt materials and which is capable of adjusting the proportion between the external air and the bitumen fumes in the admixture. The main advantage of the described plant is the reduction of the pollutants in the fumes discharged from the chimney of the installation to a level below the levels imposed by the standard. |
