  • Fluid fuel combustion process and turbulent-flow burner for implementing same
    Patent number: 4919611
    Abstract: In this combustion process a fluid fuel such as pulverized coal mixed with primary air is injected along an axis and secondary air is injected along a helical path around the axis. Tertiary air is injected around the combustible fluid and the secondary air in substantially the same direction as the combustible fluid, in a substantially circumferentially continuous coaxial ring which is laterally confined downstream of the injection point.
    Type: Grant
    Filed: April 17, 1989
    Date of Patent: April 24, 1990
    Assignee: Charbonnages de France
    Inventor: Gerard Flament

  • Device for supplying a powdery product in gravimetrically metered amounts to a pneumatic line
    Patent number: 4669921
    Abstract: A gravimetric metering apparatus with a constant throughput is enclosed inside a sealed chamber and connected through the wall of the chamber, by a first pipe, to a pneumatic conveyor line operating under a pressure of n bars and, by a second pipe, to an intermittentently operated external loading hopper. The chamber is filled with gas under a pressure of n bars which is equal to that inside the pneumatic conveyor line.
