Fuel particle separator disposed upstream from a boiler, and provided with an isolating valve member

Abstract
A separator is disposed between a grinder and a boiler so as to select, on the basis of size, particles 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. The separator extends in an axial direction and includes output compartments, each of which underlies a respective conveyor duct connecting the separator to the boiler. An isolating valve member is mounted to move inside the separator, and is moved 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 from passing therethrough. This isolating valve member makes it possible to close all of the output compartments together. In this way, it is possible to reduce the number of isolating valve members to the number of separators in a grinding installation, regardless of the number of conveyor ducts from each separator.
