A turbine bucket consists of a leading edge, trailing edge, root portion, and tip portion. Turbine buckets also include cooling holes for cooling liquid running through the bucket. First stage buckets are the first surface that the gases from the first nozzle encounter.

The rotor of a Pelton turbine [Figure 1.1(h)] which is a hydraulic turbine consists of circular disc with a number of blades (buckets) spaced around the periphery. One or more nozzles are mounted in such a way that each nozzle directs its jet along a tangent to the circle through the centres of the buckets.

A rotor assembly comprised of a multiplicity of blades mounted around the periphery of a disk has the blade tips ground to great diametrical precision when the assembly is rotated at a high speed in excess of 1000 rpm in a special grinding process. Individual blade lengths are dynamically measured while the assembly is being ground. These measurements are used to control the …

The tip is applied as a powder metallurgy or sintered pre-form material and fused to the tip in a vacuum furnace. It's not uncommon for a turbine bucket to suffer rub wear and high-temperature oxidation at the tip, Cooke told the group. Original alloys and conventional coatings are unable to prevent oxidation in high-performance engines.

A CNC grinding machine is a precision performance tool that uses a rotating wheel to cut material away from metal. Usually, CNC grinding machines are used during the finishing process to create a high-quality metal workpiece for camshafts, ball bearing, transmission shafts, and other working pieces that require precision and perfect finishes.

According to a feature of the present invention, there is provided a method of forming a cored turbine bucket, comprising forming a core in a mold, extending the core radially inward from a tip end of the mold to produce a radial cavity in an aerodynamic section of the bucket, allowing an uncored section between an end of the core and at least ...

All of our tip measurement systems are used for measuring tip clearance gaps between compressor and turbine blade tips and the engine inner casing. The ROTAGAGE rotor inspection system is used for measuring individual rotor blade radii on the production of gas turbine engines and compressors during the blade tip grinding process.

Pelton Wheel Turbine is the type of impulse or hydraulic turbine which is used for high heads for the generation of power. In this, the jet after leaving the nozzle runs in the open air and strikes the bucket or vane. The Pelton wheel turbine is developed by Lester Allan Pelton, who is an American Engineer.

The gas turbine efficiency, which is the function of turbine inlet temperature and the compression ratios, has increased significantly in the past decades, making it possible to reach 40–45% efficiency in simple cycle and beyond 60% efficiency (LHV) in natural gas fired combined cycles, a remarkable improvement over the E-class gas turbine ...

A bucket tip shroud in a gas turbine includes a seal rail having a cutter tooth at one end. Bucket tip shroud creep rate can be reduced by removing the cutter tooth from the bucket tip shroud seal rail after use or with a pre-groove honeycomb shroud. Preferably, the remaining geometry matches a geometry of the seal rail within a predetermined tolerance.

• The fraction of the year the turbine generator is operating at rated (peak) powerrated (peak) power Capacity Factor = Average Output / Peak Output ≈ 30% • CF is based on both the characteristics of the turbine and the site characteristics (typically 0.3 or above for a good site) Power Curve of 1500 kW Turbine Wind Frequency Distribution ...

A third-party contractor verified proper tip grinding using the latest UT (ultrasonic test) tools. The combined cycle gas turbines suffered heavy rubs within six months of its COD as was the case at the peaker station. But as the speaker said at the outset, hard rubs are conducive to tip liberations over time.
