  • Flare for and method of flaring high velocity gas
    Patent number: 4604047
    Abstract: Method and apparatus for flaring high velocity gas, especially of sonic order, by burning in the vicinity 48 of the gas outlet 41 a low velocity gas in a stable energetic flame able to maintain combustion of the main flame even under considerable lift off, i.e., to a distance greater than is maintainable by a conventional pilot or flame retention device. The low pressure gas is derived at least in part 43, 36 as a portion 44 of the high pressure gas supply having been expanded to low pressure.

  • Heat exchanger assemblies
    Patent number: 3976127
    Abstract: A heat exchanger comprising an A or V frame with finned tubes running parallel with the apex of the V in which the apex of the frame is filled with tubes rather than being blanked off thus increasing the available heat-exchange area. Also an assembly of such heat exchangers arranged side by side to have a zig-zag section and in which all apices of the section are tubed. An assembly or assemblies of such heat exchangers may be arranged in a natural draught tower or have fan means associated therewith.
