Abstract: An apparatus and method for establishing a stable pilot flame at a wide range of operating conditions, having a main fuel tube (10), an outer tube (20) concentrically enclosing the main fuel tube, a swirler (30) located downstream from the outer tube, an ignitor (40), and several fuel manifold tubes (50) connected to the main fuel tube, are disclosed. The fuel manifold tubes direct a portion of the pilot gas fuel stream radially outward from the remainder of the pilot fuel. The axial momentum of the radially displaced fuel stream is greater than the average axial momentum of the remainder of the pilot gas streams. This relationship between the axial momenta of the gas streams promotes flame recirculation and stabilizes the pilot flame over a wide range of operating conditions.

Abstract: A functional approach to an information display system that enables a fast and easy understanding of the status of a complex process. The display screen is organized by process goals. Each process goal is then tied to a number process objectives which directly relate individually to the goals. The objectives are in turn tied to the process functions which must be substantially maintained in order to achieve the respective objectives. A display of control functions related to each process function is mapped onto the regional displays. The individual display elements use a combination of coded background color, border color and other indicia of information, e.g., mimics, meters, etc. to present a significant amount of information about the status of the process and its components in a manner that is readily absorbed and easily understood.

Abstract: An ultra-low NOx gas turbine combustor having a dual fuel capability. The combustor has a plurality of venturis in flow communication with a corresponding number of fuel lances such that fuel injected from each lance into a corresponding venturi is mixed with high velocity air also flowing into the venturis. A vee-gutter flame holder is positioned downstream of the array of venturis for holding a combustion flame within the combustor at stable conditions. Due to the high velocities of the air-fuel mixture in the vicinity of the flame-holder, as a result of the fuel-air mixing in the venturis, destructive flash back conditions are obviated. A stable flame within the combustor provides for minimum acoustic disturbance and low overall pressure losses within the combustor provide for high operating efficiency levels of the turbine apparatus. Burning of the fuel in air at lean mixtures allows for minimal operation of a conventional pilot nozzle assembly so as to reduce the undesirable formation of NOx.

Abstract: The inter-disk cavity between turbine rotor disks is used to pressurize cooling air. A plurality of ridges extends radially outwardly over the face of the rotor disks. When the rotor disks are rotated, the ridges cause the inter-disk cavity to compress air coolant flowing through the inter-disc cavity en route to the rotor blades. The ridges eliminate the need for an external compressor to pressurize the air coolant.

Abstract: An apparatus for and method of continuously supplying a conditioned fuel, such as CO and H2, to an electrochemical generator such as a high temperature solid oxide electrolyte, fuel cell generator (SOFC) (12, 14), for electrochemical reactions and continually regenerating a hydrocarbon reformation catalyst by providing at least two iron metal/iron oxide beds. At least one bed, a reformation bed (48), is mainly in the iron oxide (FeO) condition and incoming hydrocarbon feed fuel gas, such as natural gas, will be reformed or conditioned at a temperature of about 600 DEG C to 800 DEG C on the iron oxide to CO and H2 which represents the fuel to be fed to the fuel cells of the electrochemical generator, thereby reducing iron oxide to iron metal (Fe). While the FeO reformer bed is being reduced to Fe, the at least one other bed, an oxidation bed (50), which previously served as a reformer bed mainly in the iron metal condition (Fe) is oxidized at a temperature of about 600 DEG C to 800 DEG C to mainly FeO form with generator spent fuel gases, thereby oxidizing iron to iron oxide and also producing some additional conditioned fuel gas. The beds can be operated concurrently or sequentially, and when each bed becomes substantially exhausted, it is switched over in function to the other mode of operation.

Abstract: A component maintenance system having a network linked to a data acquisition system, a data analysis system, a historical file of component design and inspection information, and a diagnostic system having the capability to perform structural analysis of discontinuities identified by the data acquisition system. The network nodes may be located apart from each other; for example in the maintenance of a nuclear power plant steam generator, the data acquisition system may be located in a high radiation area while the data analysis system is safely located away from the radiation areas. Furthermore, the diagnostic system and the file of component design and inspection history information may be centrally located and shared to support component evaluations being conducted in numerous geographic locations. Network communication facilitates the rapid evaluation of discontinuities, thereby permitting the inspection plan to be modified as the inspection results are obtained.
