A refurbishing method, refurbishing apparatus and refurbished article are provided. The refurbishing method includes accessing a plurality of rotatable components attached to a turbine assembly, the turbine assembly being a portion of a turbomachine, providing a predetermined volume of a buffered electrolytic solution in an electro-polishing tank, coupling the plurality of rotatable components to a power supply, immersing an immersion portion of at least one of the plurality of rotatable components in the buffered electrolytic solution, passing an electrical energy through the immersion portion of at least one of the plurality of rotatable components while the immersion portion is immersed in the buffered electrolytic solution, wherein an electrical flux to the immersion portion electro-polishes the immersion portion, separating the immersion portion from the buffered electrolytic solution, and applying a corrosion inhibitor to the plurality of rotatable components.

The present application thus provides an active cooling system (100) for a compressor (15) and a turbine (40) of a gas turbine engine (10). The active cooling system may include an air extraction pipe (70,80) extending from the compressor (15) to the turbine (40), a heat exchanger (130,140) positioned about the air extraction pipe (70,80), and an external air cooling system (150) in communication with the air extraction pipe (70,80).
摘要:
A system and method is provided that improves the under frequency response of gas turbines by providing a fast-response power augmentation system. The system includes a tank (102) storing a blended mixture of motive fuel such as ethanol or methanol and demineralized water in a predetermined ratio that is provided as a diluent to be injected into the compressor bellmouth (136), the Compressor Discharge Chamber (CDC) (138), and/or the combustion system (140) via one to three dedicated circuits. To achieve the instantaneous injection of the diluent at the correct pressure and for the appropriate duration to meet the needs of the gas turbine Grid compliance mandate, an accumulator is used as the motive force to drive the augmentation fluid in the dedicated circuits (134). The injected diluent is microprocessor controlled to either be simultaneous into all three circuits (134) or is sequenced based on a determination of the best turbine control and performance.

摘要:
A supercharging system includes a fan (130) providing an air flow, and a prime mover (131) that drives the fan (130). A duct (132) directs a first portion of the air flow to a gas turbine system (113), a main bypass subsystem (133) diverts a second portion of the air flow to a heat recovery steam generator (123); and a drive bypass subsystem (145) that diverts a third portion of the air flow to the prime mover (131). The prime mover (131) may be one of an aeroderivative gas turbine, a gas turbine, a reciprocating engine, a steam turbine and an induction motor and a variable frequency drive.
摘要:
Methods and systems for imparting corrosion resistance to gas turbine engines are disclosed. Existing and/or supplemental piping is connected to existing compressor section air extraction (110) and turbine section cooling air piping (130) to supply water and anti-corrosion agents into areas of the gas turbine engine (10) not ordinarily and/or directly accessible by injection of cleaning agents into the bellmouth (60) of the turbine alone and/or repair methods. An anti-corrosion mixture is selectively supplied as a liquid-steam mixture to the compressor (20) and/or the turbine sections (30) of the gas turbine engine (10) to coat the gas turbine engine components therein with a metal passivation coating which mitigates corrosion in the gas turbine engine.
