Open the CIPO recordAbstract From the Canadian patent
A pulverized coal-air stream or auxiliary air stream discharging into a furnace (1) from a delivery pipe (12) is deflected away from the longitudinal axis of the delivery pipe by directing a working fluid stream, preferably air or flue gas, against the coal-air or auxiliary air stream as it approaches the outlet of the delivery pipe so as to impinge thereagainst at an angle of substantially ninety degrees. The resulting angle of deflection of the coal-air or auxiliary air stream away from its longitudinal axis is controlled by varying the momentum of the working fluid stream impinged against it.
