Llinares, V

A pulverized coal-fired burner having a longitudinally elongated coal delivery pipe through which a stream of pulverized coal entrained in air is passed into the furnace and at least two air plenum chambers, one along the top and one along the bottom of the coal delivery pipe, connected in fluid communication with the interior of the coal delivery pipe at the discharge end thereof. A high pressure working fluid, such as air or flue gas, is passed through the plenum chambers into the coal delivery pipe so as to impinge against the coal-air stream passing therethrough thereby causing the coal-air stream to be deflected away from the longitudinal axis of the coal delivery pipe.
