Digmesa used PEEK for the two epicycloid vanes located in the flowmeter's two epicycloid turbines, according to Victrex. |
|
Fuel Conditioning Systems for gas turbine fuel oils are the systems which control the supply of fuel from the day tanks to the gas turbines. |
|
Gas turbines can also be turned on and off much more rapidly than steam plants, so they can be switched on when demand for power peaks, such as on hot summer afternoons. |
|
Natural gas turbines generate carbon, which pollutes the environment of many countries and environmental regulation requiring upgrades of inefficient gas turbine power plants. |
|
Omega will supply the turbines, electrical generators, electrostatic precipitators and steam generating equipment needed to support the Biosphere Process Systems. |
|
The report analyzes the revenues, average price and volume sales of gas turbines by capacity ratings used for power generation in key ten countries in the market. |
|
Blyth lifeboat crew were able to establish contact with the second kayaker by VHF radio and quickly locate them both just off-shore of the wind turbines in Cambois Bay. |
|
There aren't enough wind turbines in the world to outpower humankind's appetite for energy, a study by University of Oregon researcher Richard York has found. |
|
Because gas turbines optimally spin at high speed, a turboprop features a gearbox to lower the speed of the shaft so that the propeller tips don't reach supersonic speeds. |
|
Aircraft engines are almost always either lightweight piston engines or gas turbines, except for small multicopter UAVs which are almost always electric aircraft. |
|
Industrial gas turbines can create up to 50,000 shaft horsepower. |
