The invention concerns an arrangement to counteract problems associated with mixing in steam into a pipe that is transferring a flow of pulp of medium consistency. The arrangement comprises a chamber (101) with a cross-sectional area (A3), and a pre-determined length (x). The chamber (101) is in connection, upstream to the flow of pulp, with a first throttle section (107) that has a cross-sectional area (A1). The addition of steam through supply means (105) takes place in the first throttle section (107). The chamber (101) is in connection, downstream to the flow of pulp, with a second throttle section (122) that has a cross-sectional area (A2). The cross-sectional area (A3) of the chamber is greater than the cross-sectional area (A1) of the first throttle section and the cross-sectional area (A2) of the second throttle section. The decrease in area between the cross-sectional area (A3) of the chamber and the cross-sectional area (A2) of the second throttle section takes place instantaneously, in one single step.

Disclosed herewith is a microchip having a micromixer therein. The mixromixer employs a mixing or extracting structure having (1) a first flow pass provided at a first level of the microchip; (2) a second flow pass provided at a second level of the microchip, which is different from the first level; (3) a third flow pass having a plurality of sub flow passes separately layered at the first level and each having a first end and second end thereof, each sub flow pass being connected to one of the first and second flow passes at the first end thereof; and (4) a fourth flow pass, provided at the first level, connected to the second ends of the sub flow passes so that, at least connecting portions between the fourth flow pass and the sub flow passes of the third flow pass, an extending direction of the fourth flow pass is substantially identical to those of the sub flow passes. By allowing the first liquid to flow from the first flow pass to the fourth flow pass through the third flow pass while the second liquid to flow from the second flow pass to the fourth flow pass through the third flow pass, the first and second liquids are mixed at the fourth flow pass.

A hot air generator using a gaseous fuel. The generator comprising a tubular body carrying air to be heated, a mixing tube carrying gaseous fuel and primary air to a burner located at the downstream end of the mixing tube. Radially fins or blades are disposed in the burner constituting a centrifugal fan. A combustion chamber is generally coaxially arranged in the tubular body generally downstream of the centrifugal fan means. The downstream wall of the burner formed by a heat grid permitting the passage of the fuel mixture for forming a flame on its surface.

The present invention relates to an apparatus and method for mixing and atomizing a hydrocarbon stream using a diluent/dispersion stream. The apparatus includes an inner conduit having an inlet for receiving the diluent/dispersion stream; an outer conduit having an inlet for receiving the hydrocarbon stream and an outlet for dispensing a mixture including the hydrocarbon and the dispersion/diluent streams; the outer conduit concentric to the inner conduit to define at least a first annular space and a second annular space; the first annular space being located downstream of the inlet of the outer conduit, the first annular space enabling formation of a thin film of the hydrocarbon stream between an outer surface of the inner conduit and an inner surface of the outer conduit; the second annular space being located downstream of the first annular space, the second annular space having a width greater than a width of the first annular space; and the inner conduit located at about the second annular space includes a first set orifices disposed on a periphery thereof for dispensing a first portion of the dispersion/diluent stream into the thin film of hydrocarbon stream to cross-shear the thin film and form the mixture including the hydrocarbon and the dispersion/diluent streams.

A method and apparatus for mixing fluids, such as beverage syrup and water, uses countercurrent injection to improve blending of the fluids. A mixing chamber has a first inlet through which a first fluid is fed to the mixing chamber, and a second inlet through which a countercurrent injection nozzle extends and is operative to inject a second fluid into a stream of the first fluid. The countercurrent injection nozzle is equipped with a check valve to control the flow of fluid into the mixing chamber. The mixing chamber may include additional inlets that may be fitted with countercurrent injection nozzles to permit the countercurrent injection of other fluid, such as flavorings, into the stream of the first fluid.

A baffle includes a body member having a first surface, a second opposed surface, and an outer peripheral edge. An aperture may be formed through the body member to define an inner peripheral edge. The inner peripheral edge is distorted to be non-planar. An apparatus includes a first conduit having a first end, a second end, and a first channel extending therebetween. At least one baffle is disposed in the first channel and includes a body member having a first surface, a second opposed surface, and an outer peripheral edge. At least one aperture may be formed through the body member to define an inner peripheral edge. The inner peripheral edge is distorted to be non-planar. A second conduit may be disposed inside the first conduit and extend through the aperture in the baffle. The apparatus may be an ultraviolet light reactor, a heat exchanger, or a static mixer.
