A system for measuring a flow rate of a fluid through a plurality of tubes sharing a common flow orifice, the system includes an ultrasonic transducer having a plurality of sensors in communication with a plurality of tubes sharing a common flow orifice. The system includes an electronic module coupled to the ultrasonic transducer, the electronic module connecting selected sensors to a flow rate analyzer for determining a flow rate of fluid through the plurality of tubes on which the sensors are in communication with.

Method and system for measurement of a flow rate of a fluid

A start-up system mixing element including; a body defining a cavity, a first inlet port disposed in the body and configured to provide a first fluid to the cavity, a second inlet port disposed in the body and configured to provide a second fluid to the cavity, an outlet port disposed in the body and configured to remove the first and second fluids from the cavity and an internal distribution pipe disposed in the first inlet port, wherein the internal distribution pipe is configured to provide the first fluid to the cavity via a plurality of holes directed toward a center of the cavity.

In order to maintain the flue gas temperature from a steam generator up to the temperature required for a NO.sub.x catalytic reactor during low load operations, the flow of feedwater through the steam generator economizer is controlled to control the degree to which the flue gas is cooled as it passes over the economizer heat exchange surface. More specifically, an economizer bypass line is provided and the flow of feedwater during low load operations through the bypass line and the economizer is regulated to maintain a desired flue gas temperature to the catalytic reactor. As the flue gas temperature changes with load, the flow through the economizer and bypass line is modulated to maintain a proper temperature. At full or near full load, the bypass line is fully closed.

A liquid-vapor separator for two-phase fluids in general and specifically a steam-water separator in a steam drum of a steam generator includes axial or radial spinner blades to create a centrifugal motion which causes liquid to be forced outward against the outer wall and the vapor to be concentrated in the center. Conical extraction skimmers systematically extract and discharge the liquid outwardly and downwardly through the side walls such that it impinges on an optional discharge screen surrounding the skimmers. The vapor flows out the top through a central opening and enters a secondary separator packed with crimped wire mesh encased in a perforated enclosure. The conical extraction skimmers include an outwardly protruding rim portion which forms an enlarged annular chamber between the rim and the underlying conical extraction skimmer. This forms a converging-diverging flow path out between skimmer sections and an outwardly extending ring forms a tortuous path. Inwardly extending extraction lips of varying size on the top of each skimmer enhance the liquid extraction.

Conical extraction skimmers systematically extract and discharge the liquid outwardly and downwardly through the side walls such that it impinges on an oval discharge screen surrounding the skimmers. The vapor flows out the top through a central opening and enters a secondary separator packed with crimped wire mesh encased in a perforated enclosure.
