Recycling wind turbine blades

Renewable Energy Focus, 2009
WITH A BOOMING WIND ENERGY INDUSTRY, DRIVING THE DEVELOPMENT OF LARGER AND LARGER TURBINES, THE QUESTION IS NOW ARISING OF HOW TO DEAL WITH WIND TURBINES AT THE END OF THEIR LIFECYCLE, AND PARTICULARLY THOSE WIND TURBINE BLADES MADE OF HARD-TO-RECYCLE COMPOSITES. RENEWABLE ENERGY FOCUS' KARI LARSEN INVESTIGATES POSSIBLE ROUTES FOR THE RECYCLING OF WIND

Turbine Blade Damper

2001
For a reduction of blade vibration amplitudes in airborne gas turbines special damper devices are used which usually are arranged between the blade platforms of neigboring blades. These dampers possess a cross section like a parabola or a circle and are formed out of sheet steel.

Turbine blade vibration dampening

The Journal of the Acoustical Society of America, 1998
The present turbine wheel assembly increases component life and turbine engine longevity. The combination of the strap and the opening combined with the preestablished area of the outer surface of the opening and the preestablished area of the outer circumferential surface of the strap and the friction between the strap and the opening increases the ...

Titanium Steam Turbine Blading

1990
The use of titanium alloys for the long last stage and L-1 stage of low-pressure steam turbines has been in development for over 30 years, and appears to be entering commercial use. The titanium blades are used in the steam transition L-1 row, because they are immune to pitting corrosion by the corrosive early condensates at the Wilson line.

Turbine Blade Failure

2019
Abstract Three blades from 45,000 kW, 3,000 rpm turbine were received for examination, comprising the root of blade 28, blade 89 showing a crack in one of the root teeth, and blade 106 which was free from defects. Microscopic examination of the blade material showed it to be a ferritic stainless steel of the type commonly used for ...

Wind turbine blade inspection

2020
Devido a preocupações climatéricas, energia renovável é uma importante fonte energética. Energia eólica desempenha um importante papel na produção de energias renováveis e é produzida por geradores eólicos. Estes estão sujeitos a danos e requerem inspeção regular. Esta tarefa é realizada manualmente e é um procedimento demorado, perigoso e dispendioso.
