How does OTEC work? (ocean thermal energy conversion

What is OTEC? Most of the electricity we use comes from heat engines of one kind or another. A heat engine is a machine that cycles between two different temperatures, one hot and one cold, usually extracting heat energy from a fuel of some kind. In a steam engine or a steam turbine, for example, coal heats water to make hot, high-pressure steam, which is then allowed to expand and cool down

History of Steam

Steam released from the boiler into the cylinder pushes up the piston. When the cylinder is full of steam, the same procedure follows as in Savery's engine. Cold water poured on the outside condenses the steam and creates the vacuum. But in this case, instead of directly sucking up water, the vacuum causes the piston to descend in the cylinder.

Today, all boiler feed pumps are centrifugal pumps. The design of boiler feed pumps regarding

Steam Engine |

Steam Engine. History. The workings of a steam engine. Resources. A steam engine is a machine that converts the heat energy of steam into mechanical energy by means of a piston moving in a cylinder. As an external combustion engine — since it burns its fuel outside of the engine — a steam engine passes its steam into a cylinder where the steam then pushes a piston back and forth.
