How a Rotary Kiln Dam Works - FEECO

How a Rotary Kiln Dam Works. A dam in a rotary kiln works much like a dam in a river; material builds up behind the dam, forcing retention time and bed depth to increase. Material then spills over the dam, and discharges from the rotary kiln. Since most kilns utilize a counter current air flow, end dams are the most commonly employed type of dam.

How Hydropower Works | Wisconsin Valley Improvement Company

For the dam in our area, lets say we buy a turbine and generator with an efficiency of 80%. Then the power for our dam will be: Power = (10 feet) x (500 cubic feet per second) x (0.80) / 11.8 = 339 kilowatts. To get an idea what 339 kilowatts means, let's see how much electric energy we can make in a year.
