Device and a method for injecting a fluid internally of a flow of loose material

A device for injecting a fluid internally of a flow of loose material, comprising a feeder (2) of loose material (100), provided with a lower discharge mouth (24) through which the loose material (100) flows along a descending direction (Y), an injector (3), predisposed to inject a fluid onto the loose material (100), which injector (3) is located below the discharge mouth (24) such as to be positioned internally of the flow of loose material (100);

• the injector (3) is arranged along the descending direction (Y) and comprises at least two nozzles (31) for emitting the fluid, which nozzles are facing downwards;
• characterised in that the at least two nozzles (31) are arranged symmetrically with respect to the descending direction (Y) and inclined such as to diverge with respect to one another, and the device comprises a motor device (4) predisposed for enabling movement of the injector (3) along a longitudinal direction (Z) perpendicular to the descending direction (Y).
