An erosion sensor that can separately monitor erosion and corrosion of a substrate, such as a wind turbine blade or a turbine blade used in devices such as gas turbines, aircraft engines, microturbines, steam turbines, and the like is disclosed. The sensor can include a first element or “erosion part” that is made of a corrosion resistant material. The first element of the sensor has similar erosion properties to the substrate being monitored. The sensor can further include a second element or a “corrosion part” that is made of a material having similar erosion and corrosion properties to the substrate. The sensor can provide an erosion indicator based on the erosion of the first element and a corrosion indicator based on the erosion and corrosion of the second element.

A creep indication system and a method for determining a creep amount are disclosed. The system includes a first creep indicating member on a first rotating component and a second creep indicating member on a second rotating component. The second creep indicating member has at least one different creep characteristic from the first creep indicating member. The system further includes at least one measurement device configured to measure a change in radial position of at least one of the first creep indicating member or the second creep indicating member. The method includes measuring a first creep amount of a first creep indicating member and measuring a second creep amount of a second creep indicating member. The method further includes estimating a temperature of a rotating component using the first creep amount and the second creep amount.

A method for manufacturing a corrosion sensor includes applying a first layer of non-conductive material to a substrate, writing a conductive material at discrete locations on the non-conductive material, and writing the conductive material at discrete locations on the previously written conductive material. The method further includes applying a second layer of non-conductive material over the conductive material and machining at least a portion of the second layer of non-conductive material to expose at least a portion of the conductive material.

A system includes a gasifier, which includes a reaction chamber configured to convert a feedstock into a synthetic gas, a quench chamber configured to cool the synthetic gas, a quench ring configured to provide a water flow to the quench chamber, and a quench ring protection system configured to protect the quench ring from the synthetic gas or a molten slag. The quench ring protection system includes a protective barrier disposed within an inner circumferential surface of the quench ring. The protective barrier substantially overlaps the inner circumferential surface in an axial direction along an axis of the quench ring.

A system for laser shock peening includes a laser positioned to direct a laser pulse at a first side of a work piece and a coupler on a second side of the work piece. The system further includes a Doppler shift detector positioned to measure a velocity of the coupler. A method for laser shock peening includes depositing an amount of energy from a laser pulse into a first side of a work piece and transmitting a pulse having a first frequency at a second side of the work piece. The method further includes receiving a reflected pulse having a second frequency from the second side of the work piece and determining the velocity of the work piece based on the difference between the first frequency and the second frequency.

A feed injector for providing feed to a gasifier of an integrated gasification combined cycle system includes: a base leading to a body and terminating in a tip, the tip including an exitway for injecting feed into the gasifier; the tip including a mating of an inner shell disposed within a core insert, with an outer shell in which the core insert is disposed; a plurality of spacers disposed between the core insert and inner shell thus providing an inner annular space, and another plurality of spacers disposed between the core insert and outer shell thus providing an outer annular space; the inner annular space and the outer annular space being in fluid communication at the tip and providing for a flow of coolant from the base to the tip and back to the base. A method of fabrication and an integrated gasification combined cycle power plant are also disclosed.
摘要:
A method for repairing a hub pitch gear assembly. The method includes providing a ring assembly for adjusting a pitch angle of a wind turbine blade having a plurality of gear teeth. A segment of the ring assembly is removed, the segment including at least a portion of at least one gear tooth, to form a repair cavity. A repair segment configured to mate the repair cavity is provided and the repair segment is directed into the repair cavity and fastened in position. A repaired pitch gear assembly and wind turbine are also disclosed.

A turbine inner shroud and a turbine assembly. The turbine assembly includes a turbine stator having a longitudinal axis and having an outer shroud block with opposing and longitudinally outward facing first and second sides having open slots. A ceramic inner shroud has longitudinally inward facing hook portions which can longitudinally and radially surround a portion of the sides of the outer shroud block. In one attachment, the hook portions are engageable with, and are positioned within, the open slots.
