Steam turbine blade cracking often suggests the need for an upgraded blade design. Follow the process of reversing engineering a failed blade to produce a more reliable and efficient design. Blade ...

The majority of the world’s electricity is produced by steam turbines consisting of a cascade of turbine blades designed to optimize the efficient conversion of kinetic steam energy to rotational ...

The row of last-stage blades (LSBs) in a steam turbine’s low-pressure (LP) section is a key element of the turbine’s design because it defines the machine’s overall performance, dimensions, and number ...

Over the last 20 years, the power industry has experienced a shift in steam turbine (ST) maintenance strategies driven by two compounding factors. The first factor has become the overwhelming task of ...

Wire arc additive manufacturing allowed this robot arm at ORNL to transform metal wire into a complete steam turbine blade like those used in power plants. Researchers at the Department of Energy’s ...

Since the late 19th century steam turbines have been used for the generation of electricity. A prototype steam turbine, designed by Charles Parsons in 1890, had 15 expansion stages and was one of the ...

The term “hydroelectric power” often brings to mind immense operations driven by purpose-built infrastructure such as dam systems and large turbines with traditionally metallic, propeller-based ...

The GE9X is a smaller variant of the General Electric GE90 high-bypass turbofan engines, developed for the new Boeing 777-8x/9x aircraft and introduced in 2013. GE Aviation is designing a new, thinner ...
