Abstract:
A separator, comprising:a separator body adapted to be disposed between a grinder and a boiler, said separator body having a conveyor structure adapted to select, on the basis of size, particles of a certain maximum size by forcing said particles to travel in one direction using forced air, and allowing particles of a certain minimum size to travel in another direction under the force of gravity, all of said particles having been produced by grinding a fuel in the grinder and conveyed by a flow of air from the grinder to the separator, and then to the boiler;wherein said separator extends in an axial direction and further includes output compartments, each of which underlies a respective conveyor duct connecting the separator to the boiler; andwherein said separator further includes an isolating valve member mounted to move inside the separator in translation in the axial direction either to allow the flow to pass through all of the output compartments into the conveyor ducts or else to prevent said flow passing therethrough.
