Trozzi, N K

This patent describes a splitter for directing a mixture of coal and air from an external source to a coal fired furnace. The splitter consists of a housing for receiving the mixture; an elongated damper blade assembly disposed in the housing for dividing the mixture into two streams. The damper blade assembly is pivotable at one end portion for movement in the housing to control the quantity of mixture in each of the streams. A longitudinal edge portion of the damper blade assembly is spaced from a corresponding wall of the housing in all positions of the blade assembly to define a fixed gap for the passage of a portion of the mixture. A device connects the bars to the damper assembly for varying the size of the fixed gap.
