    摘要: The invention provides a method for mixing two or more gaseous or liquid streams, where the gaseous streams are combined in an inlet chamber and thereafter repeatedly accelerated and decelerated in one or more of stages, and a value of a maximum linear velocity of the accelerated combined gaseous stream is maintained in each step within a range of mass flow rates of the gaseous streams.The invention also provides apparatus for mixing two or more gaseous or liquid streams, one embodiment comprises a body with a seat; a spindle with a plug, which is installed in the seat and the seat and the plug have a plurality of conical surfaces forming the same plurality of conical annuli. The spindle is able to move the plug in an axial direction in the seat during the mixing.Another embodiment comprises a body, a spindle with a tube plug. A cage and annular mixing elements surround the tube plug.

    摘要: The invention relates to a process for the production of electricity in a fuel cell system by steam reforming a carbonaceous fuel to form fuel cell reactant gas and recycling recovered reactants from the anode exhaust gas to the anode inlet. There is obtained an increase of the electricity production of 20-30% if prior to the recovery and recycling the anode exhaust gas is passed over a steam reforming catalyst by which lower hydrocarbons in said exhaust gas is converted to reactants for use in the fuel. The carbonaceous fuel may for instance be natural gas or methane. A fuel cell system for use in the process comprises supply means (2,10) for carbonaceous fuel; an inlet reformer unit (6) for producing reactant gas for the fuel cell (4); an outlet reforming unit (12) for converting hydrocarbon-containing anode exhaust gas to anode reactant gas; and means (18,90) for recovering the reactant gas and recycling recovered anode reactant gas.
