    Abstract: An economizer apparatus (109) for a fossil fuel fired vapor generation apparatus (10) which includes a housing having an inlet and an outlet and a wall extending generally between the inlet and the outlet to define first and second flow paths in the housing. The inlet may include means for connection to an associated vapor generation apparatus and means for connection to an associated stack. Heat exchange tubing (112) is disposed in the first flow path having the interior thereof coupled to associated working fluid of the vapor generation apparatus (10). The apparatus (109) also includes apparatus (114) in the second flow path to control flow in the second flow path. In most embodiments of the invention the apparatus (109) also includes a bypass conduit (120) for selectively directing fluid flow around the heat exchange tubing (112). Ordinarily this will be desirable when the damper (114) is obstructing fluid flow in the second flow channel.

    Abstract: A stabilized alpha metal matrix provides an improved ductility, creep strength, and corrosion resistance against irradiation in a zirconium alloy containing tin in a range of 0.45 to 0.75 wt. %, and typically 0.6 wt. %; iron in a range of 0.4 to 0.53 wt. %, and typically 0.45 percent; chromium in a range of 0.2 to 0.3 wt. %, and typically 0.25 percent; niobium in a range of 0.3 to 0.5 wt. %, and typically 0.45 wt. %; nickel in a range of 0.012 to 0.03 wt. %, and typically 0.02 wt. %; silicon in a range of 50 to 200 ppm, and typically 100 ppm; and oxygen in a range 1000 to 2000 ppm, and typically 1600 ppm, with the balance zirconium. The addition of iron and niobium improves mechanical properties of the alloy with its lower lever of tin, while corrosion resistance is addressed by having an iron level of 0.45 wt. % and an iron/chromium ratio on the order of 1.5. The addition of niobium also conters the effect of higher iron on the hydrogen absorption characteristics of the alloy. The addition of nickel, silicon, carbon and oxygen as alloying elements provide desired corrosion resistance and strength.

    Abstract: A nuclear reactor fuel assembly having flow modulators in the form of mixing vanes (28) and/or flow deflectors. The flow modulators are formed in substantially planar intersecting grid strips and have portions (28a) which have been cold-worked by shot peening on one side. Under neutron flux, the cold-worked portion (28a) preferentially expands forcing a bending of the flow modulator with increased reactor life. This concurrently causes an increase in pressure drop across the fuel assembly over the fuel assembly life.

    Abstract: Equipment for acquiring diagnostic data from a valve train parameter that changes as a result of the operation of a valve (14) in a process plant is positioned as an auxiliary data acquisition unit (200) in the vicinity of the valve train. A plurality of sensor lines (P3, P4) are connected between the auxiliary unit and locations in the valve train where the parameter changes. The valve is operated so as to generate parameter signals manifested in a first physical form in the sensor lines. In the auxiliary unit, the physical form of the parameter signals is converted into diagnostic signals (E10, E11) having a different physical form. The diagnostic signals are transmitted to a base data acquisition unit (100) that is physically distinct from the auxiliary unit.

    Abstract: An advanced overfire air system for NOx control designed for use in a firing system of the type that is particularly suited for use in fossil fuel-fired furnaces and a method of operating such a furnace which embodies an advanced overfire air system. The advanced overfire air system for NOx control includes multi-elevations of overfire air compartments consisting of a plurality of close coupled overfire air compartments (84, 86) and a plurality of separated overfire air compartments (94, 96, 98). The close coupled overfire air (84, 86) compartments are supported at a first elevation in the furnace (10) and the separated overfire air compartments (94, 96, 98) are supported at a second elevation in the furnace (10) so as to be spaced from but aligned with the close coupled overfire air compartments (84, 86). Overfire air is supplied (106, 92) to both the close coupled overfire air compartments (84, 86) and the separated overfire air compartments (94, 96, 98) such that there is a predetermined most favorable distribution of overfire air therebetween, such that the overfire (106) air exiting from the separated overfire air compartments (94, 96, 98) establishes a horizontal "spray" or "fan" distribution (124, 126, 128) of overfire air over the plan area of the furnace, and such that the overfire air (106) exits from the separated overfire air compartments (94, 96, 98) at velocities significantly higher than the velocities employed heretofore.

    Abstract: Laser light from the laser light source (14) is conveyed by means of the laser light conveying device (40) to the collimator. After being collimated the laser light is transmitted to the first focusing device (64) whereby the laser light is focused and is then made to pass across the sample path (74). The laser light is scattered by the particles that are present in the sample path (74). Both scattered and collimated light is collected by the second focusing device (78) and then focused thereby on to the detector device (82) such that the intensity distribution of the laser light is gathered by the detector device (82). Particle size distribution is inferred from the light distribution received by the detector device (82).
