Abstract
An apparatus for use in a furnace system to facilitate efficient and complete combustion of coal streams in a carrier gas. The apparatus, capable of being positioned horizontally or vertically in the coal pipes between the grinding mills and the furnace burner, contains a plurality of adjustable blades that are movable between an open and closed position. The position of the adjustable blades and the differing geometric shapes of the apparatus housing manipulate the amount and direction of coal streams in a carrier gas. This design reduces the amount of turbulent eddies in the pipe system, which helps to achieve a more homogenous flow of coal in a carrier gas and the efficient and complete combustion of coal in a carrier gas within the furnace burner.
