Body for improving the efficiency of a wind turbineHENRIK STIESDAL BONUS ENERGY A/S
In order to preserve the efficiency and power of a gas turbine, the clearances between rotating blades and the interior casing should be as small as possible. To obtain that, one sprays a sacrificial material by an atmospheric plasma spraying torch and obtains a coating layer. During their rota...

A distinction is made between the efficiency of one stage of a machine or installation and the efficiency that characterizes the entire energy conversion chain in a system. Efficiency of the first type may be mechanical, thermal, and so on, depending on the nature of the energy conversion. The...
An inertial particle separator is one method of reducing the amount of sand and dust ingested by gas turbine engines. This is important because sand and dust often limit the useful life of engines operating in austere environments. To further improve the efficiency of inertial particle separator sy...
The effects of heat leaks, hot-cold reservoir temperature ratios, turbine and compressor isentropic efficiencies, and total conductances of heat exchangers on the maximum thermal efficiency and its corresponding parameters are studied. The optimum conductance ratio could be found to effectively use the ...
Turbine hydraulic assessment and optimization in rehabilitation projects As turbines age after years of operation, a major rehabilitation is needed to give new life. The owner has two choices: resetting the turbine to the original state or an upgrade with new hydraulic components designed and optimize...
