What is a steam engine?

Best Answers

A steam engine is a heat engine that performs mechanical work using steam as its working fluid. Steam engines are external combustion engines, where the working fluid is separated from the combustion products. Non-combustion heat sources such as solar power, nuclear power or geothermal energy may be used. read more

A brief treatment of steam engines follows. For full treatment of steam power and production and of steam engines and turbines, see Energy Conversion: Steam engines. In a steam engine, hot steam, usually supplied by a boiler, expands under pressure, and part of the heat energy is converted into work. read more

A steam engine is a heat engine that performs mechanical work using steam as its working fluid. In simple terms, the steam engine uses the expansion principle of chemistry, where heat applied to water transforms the water to steam. and then pushes a piston (cylinder). read more

In a reciprocating engine, the piston and cylinder type of steam engine, steam under pressure is admitted into the cylinder by a valve mechanism. As the steam expands, it pushes the piston, which is usually connected to a crank on a flywheel to produce rotary motion. read more

The Newcomen steam engine used the force of atmospheric pressure to do the work. This process begins with the engine pumping steam into a cylinder. The steam was then condensed by cold water, which created a vacuum on the inside of the cylinder. The resulting atmospheric pressure operated a piston, creating downward strokes. read more
