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.

A material feed apparatus for influencing the travel properties of a feed stream of material moving between a pulverizer and a furnace includes a feed path passing through an upstream passage periphery UPZ. The feed path includes one duct A having a branch entry A and another branch duct C having a branch entry C both downstream of the upstream passage periphery UPZ through which the feed stream of the material travels in two segregated portions. A Y-axis drive assembly and the X-axis drive assembly move the nozzle relative to the reference axis RA, whereupon the upstream passage periphery UPZ moves relative to the reference axis RA such that the travel properties of the one portion of material in the one branch duct A are different than its travel properties before the movement of the upstream passage periphery UPZ.

An energy-efficient grinding roll for employment in a pulverizer operative for effecting the pulverization of solid material therein. The energy-efficient grinding roll includes a body portion formed of a first type of material, an external surface formed of a second type of material, and tread-like means of preestablished dimensions and preestablished spacing provide on the external surface such that the energy-efficient grinding roll is capable of achieving as much as a 15% reduction in the energy required to pulverize solid material when compared with the use of standard grinding rolls.

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.

A liquid level measuring system for the steam drum of a steam generator employs a plurality of bubblers spaced along the length of the drum to obtain a level profile. The steam pressure to the bubblers is supplied by tubes connected to the steam/water inlet space which has a pressure significantly higher than the steam space in the drum. Horizontal pressure taps on each bubbler transmit the pressure to pressure cells external to the drum where the bubbler pressure is compared to the pressure in the steam space. These reading can then be converted to liquid level readings.
