Everything about Benoit Fourneyron totally explained
Benoît Fourneyron (
October 31,
1802 –
July 31,
1867) was a
French engineer, born in
Saint-Étienne. Fourneyron designed the first practical
water turbine in 1827.
Benoît Fourneyron was educated at the
New School of Mines, a nearby engineering school that had recently opened. After he graduated in 1816, he spent the next few years in
mines and
ironworks.
Around this time, a number of French engineers -- including some of Fourneyron's former teachers -- were starting to apply the mathematical techniques of modern science to the ancient mechanism called the
waterwheel.
For centuries, waterwheels had been used to convert the energy of streams into mechanical power, mostly for milling grain. But the new machines of the
Industrial Revolution required more power, and by the 1820s there was enormous interest in making waterwheels more efficient.
Using one of his former teacher's proposals as a guide, Fourneyron built in 1827, at age of 25 years, his first prototype for a new type of waterwheel, called a "turbine". (The term turbine is derived from the Latin word for a spinning top). In Fourneyron's design, the wheel was horizontal, unlike the vertical wheels in traditional waterwheels. This 6-horsepower turbine used two sets of blades, curved in opposite directions, to get as much power as possible from the water's motion. Fourneyron won a 6,000 franc prize offered by the French Society for the Encouragement of Industry for the development of the first commercial hydraulic turbine.
Over the next decade, Fourneyron built bigger and better turbines, learning from his mistakes after each new model. By 1837, he'd a 60-horsepower turbine capable of a fantastic 2,300 rotations per minute. On that model, the turbine's wheel was only one foot in diameter, and it weighed just 40 pounds. It operated at 80 percent efficiency.
Within a few years, hundreds of factories used Fourneyron-style turbines. Other countries adopted the design to power their industrial machinery, too. Fourneyron's turbine could be installed horizontally with a vertical shaft. Immediately successful, it powered industry in continental Europe and the U.S., notably the New England textile industry. In
1895 Fourneyron turbines were installed on the U.S. side of
Niagara Falls to generate electric power.
