Abstract: Embodiments of a valve having a housing including an inlet, an outlet, and an interior chamber in fluid communication with the inlet and the outlet are disclosed. The valve also includes a seat fitting having a first screen held in place by a first retainer ring. The seat fitting includes a valve seat. The valve further includes an outlet fitting having a second screen held in place by a second retainer ring. The second retainer ring includes a plurality of ribs extending from a ring body such that the plurality of ribs create a gap between the ring body and the second screen. Further, the valve includes a valve plug configured to selectively engage the valve seat to open and close a passage between the interior chamber and the outlet. The seat fitting is contained at least partially within the outlet fitting to define the outlet of the housing.

Abstract: A home fuel gas refining system has a modifier for modifying a hydrogen-containing fuel to produce a modified gas. The modifier includes a hydrogen-containing fuel supply mechanism for supplying the hydrogen-containing fuel and a modifying air supply mechanism for supplying modifying air. The hydrogen-containing fuel delivered from the hydrogen-containing fuel supply mechanism and the modifying air delivered from the modifying air supply mechanism are mixed with each other by a modification fuel ejector, and then delivered to a reactor.

Abstract: A fluid mixing device (1) includes a chamber (3) and a bluff body (4) defining one end of the chamber (3). A first fluid inlet (5) is located toward an opposite end of the chamber (3) from the bluff body (4) and arranged to direct fluid toward the bluff body (4). A region substantially surrounding the bluff body (4) has a flow divider (8) defining second fluid inlet(s) (11) to the chamber (3) and mixed fluid outlets (12) from the chamber (3). A fluid flow from the first fluid inlet (5) and/or from the second fluid inlet (11) establishes a recirculating vortex system (14) within the chamber and results in a mixture of fluids from the first fluid inlet (5) and the second fluid inlet(s) (11) being directed through the mixed fluid outlets (12).

Abstract: A mixture formation means for the reformer of a fuel cell system or for a heater. The fuel feed includes a pressure impulse injection means and the mixture formation area is a swirl chamber having a discharge nozzle connected to the pressure impulse injection device. Also included is a fuel heater for preheating the fuel before injection in order to achieve complete vaporization of the fuel, such as diesel fuel.

Abstract: A tank containing an aluminum matrix and a combustible mixture includes the addition of a volume increasing diluter to a base fuel. A fuel tank, a tank of diluter and a tank of combustion enhancing additive are arranged to feed their respective products through control valves into an intermediate mixing tank. The mixed fuel is then metered into an individual consumer's tank which includes an interior aluminum mesh matrix.

Abstract: A small apparatus for the production of mixtures of LPG vapor and air, also called synthetic natural gas, with properties that allow these mixtures to be used in place of natural gas in mostly temporary installations for residential and industrial or commercial installations. The entire apparatus is designed to produce synthetic natural gas without permanent presence of operating personnel. Noise, typically associated with the operation of venturi-type vapor/air mixing devices, is suppressed by a combination of an air-intake filter and a noise-reducing device to a level that make the apparatus suitable for installations close to residential developments. A second vapor/air mixing apparatus, identical to the main system, is installed on the same support frame, acting as a backup device for the main system in situations of equipment malfunctions or temporary system overload. Equipment malfunctions are reported to centralized monitoring stations by means of a telephone-based signaling device.

Abstract: A reformer (5) which generates hydrogen-rich reformate gas by causing a catalytic reaction of fuel and air comprises a premixing chamber (12) for premixing the fuel with the air. High temperature air is supplied to the premixing chamber (12) from an air intake tube (13) via an orifice (14). A fuel injector (16) injects the fuel into the flow of the high temperature air in the premixing chamber (12) to generate fuel-air mixture. A homogenizing filter (17) homogenizes the composition of the fuel-air mixture in the premixing chamber (12) and supplies a uniform fuel-air mixture to a reforming catalyst (11).
