Turbines convert the power of rushing liquid, steam or wind into mechanical energy to-drive a generator. The generator then converts the technical power into electricity. In hydroelectric facilities, this combination is called a generating device.
Probably the most widely used turbine in Hydro-Québec's energy system. Liquid hits the side of the runner, pushes the blades after which flows toward the axis of this turbine. It escapes through draft pipe found in turbine. It absolutely was known as after James Bicheno Francis (1815-1892), the American engineer who invented the device in 1849.
Austrian engineer Viktor Kaplan (1876-1934) designed this turbine. It is just like the propeller turbine, except that its blades are flexible; their particular position are set in line with the readily available movement. This turbine is consequently suitable for particular run-of-river producing programs where the lake movement differs significantly.
Each Kaplan turbine at Brisay producing place weighs 300 tonnes... this is the fat of 50 African elephants.
Simply because they can achieve very high rotation rates, propeller turbines work for reduced minds. Consequently, this kind of turbine is suitable for run-of-river power stations.
