Abstract
A coal pulverizer is connected to the burner nozzles of a tangentially-fired furnace with conduits of varying lengths through which air-entrained coal is supplied for combustion within the furnace. An externally adjustable orifice assembly is mounted in each connecting conduit to equalize the flow of coal/air through the conduits to nozzles in the windboxes. Each orifice assembly comprises pivotable plates which move transverse the axis of the conduit to form an orifice in controlling the coal/air flow.
