Abstract: A method of cooling syngas in a gasifier is provided. The method includes channeling cooling fluid through at least one tube-bundle that includes at least three tubes coupled together within a radiant syngas cooler and extends through a reaction zone of the gasifier, and circulating reactant fluid around the at least one tube-bundle to facilitate transferring heat from the reactant fluid to the cooling fluid.

Abstract: A method and apparatus of assembling a rotary machine includes providing at least one component. The component is at least one of a rotating member and a stationary member. The method and apparatus also includes coupling the component to a monocoque nacelle structure. The monocoque nacelle structure includes an outer shell that extends over at least a portion of the component.

Abstract: Methods and apparatus for analyzing electrical insulation of an electrical machine are provided. The method includes receiving a first signal that includes a plurality of partial discharge pulses from the electrical machine and a plurality of noise pulses, receiving other signals that includes information relative to at least one process parameter associated with the electrical machine, determining the plurality of partial discharge pulses from the plurality of noise pulses, identifying characteristics of the plurality of partial discharge pulses relating to the location and character of partial discharges in the electrical machine, and determining a condition of the electrical insulation using the identified characteristics and the received information relative to at least one process parameter.

Abstract: A method of assembling a gas turbine engine includes coupling at least one turbine nozzle segment within the gas turbine engine, each turbine nozzle segment includes at least one airfoil vane extending between an inner band and an outer band, wherein the airfoil vane includes a leading edge and a trailing edge, and wherein the outer band includes a front face, a rear face, and an inner surface extending therebetween.
