<p>A tank (1) for the dosage of solid fuel, particularly in industrial ovens, comprising a first upper inlet (3) and a second upper inlet (4), respectively for the fuel and for air under pressure, a rotating internal scraper shaft (9) and a plurality of first lower outlets (23) for the pneumatic transfer of the fuel to supply ducts for the oven. In the tank the scraper shaft (9) is hollow and is connected to a third inlet (20) for air under pressure and to one or more radial ducts (26), which are perforated and provided with a plurality of perforated vanes (11). Below each of the first outlets (23) there is a dosage duct (26), i.e. a means for regulating the flow of fuel, on the lateral surface of which there is a nozzle (28) with mutually opposite holes (29) which is fed with air for fluidizing the fuel.</p> |
