  • Patent number: 4726184
    Abstract: A compact pulse-rocket engine assembly comprising an elongated substantially cylindrical housing containing an axially extending substantially cylindrical combustion chamber which terminates at one end in a nozzle means. Within the housing at the opposite end of the combustion chamber are a pair of charging chambers. Intermediate the charging chambers and the combustion chambers are a pair of valve means which are parallel and linked together for ensuring that the valves operate in unison.

  • Patent number: 4377072
    Abstract: There is provided a ceramic heat exchange module 10 having fluid inlet and outlet conduits (12,20) extending from one side of horizontal manifolds (14,18). Serpentine tubes 16 extend from the opposed sides and connect the manifolds. In use, in a fluidized bed combustor 22, the manifolds are positioned between the base 30 and air inlets 32. Serpentine tubes extend into the fluidized bed 36, the fluid inlet and outlet conduits extend through the base for coupling to a working fluid supply.

  • Patent number: 4275034
    Abstract: Hydrogenation reaction apparatus comprising a housing having walls which define a reaction zone and conduits for introducing streams of hydrogen and oxygen into the reaction zone, the oxygen being introduced into a central portion of the hydrogen stream to maintain a boundary layer of hydrogen along the walls of the reaction zone. A portion of the hydrogen and all of the oxygen react to produce a heated gas stream having a temperature within the range of from 1100.degree. to 1900.degree. C., while the boundary layer of hydrogen maintains the wall temperature at a substantially lower temperature. The heated gas stream is introduced into a hydrogenation reaction zone and provides the source of heat and hydrogen for a hydrogenation reaction. There also is provided means for quenching the products of the hydrogenation reaction. The present invention is particularly suitable for the hydrogenation of low-value solid carbonaceous materials to provide high yields of more valuable liquid and gaseous products.

  • Patent number: 4206032
    Abstract: A method for reacting pulverized coal with heated hydrogen-rich gas to form hydrocarbon liquids suitable for conversion to fuels wherein the reaction involves injection of pulverized coal entrained in a minimum amount of gas and mixing the entrained coal at ambient temperature with a separate source of heated hydrogen. In accordance with the present invention, the hydrogen is heated by reacting a small portion of the hydrogen-rich gas with oxygen in a first reaction zone to form a gas stream having a temperature in excess of about 1000.degree. C. and comprising a major amount of hydrogen and a minor amount of water vapor. The coal particles then are reacted with the hydrogen in a second reaction zone downstream of the first reaction zone. The products of reaction may be rapidly quenched as they exit the second reaction zone and are subsequently collected.

  • Patent number: 4138986
    Abstract: A domestic furnace for heating a fluid that is circulated through a residential building includes an oil burner, a firebox for combustion products of the burner, a heat exchanger and a flue. A conduit extending from outside of the building supplies outside air to the burner and to the flue through a pressure controlled damper; the combustion air supplied to the burner is filtered. The air inlet to the burner includes a damper that closes automatically when the burner is extinguished, to eliminate heat losses up the flue during furnace standby. Nitric oxide, carbon monoxide, unburned hydrocarbon, and smoke emissions are minimized by the design of the burner and firebox combination. A conventional type burner head is used, rather than a flame retention type, and its choke diameter is related quantitatively to the burner firing rate. In addition, the burner head has oversized, internal, peripheral air swirler vanes.
