A steam engine is a heat engine that performs mechanical work using steam as its working fluid.
Steam engines are external combustion engines,[1] where the working fluid is separate from the combustion products. Non-combustion heat sources such as solar power, nuclear power orgeothermal energy may be used. Water turns to steam in a boiler and reaches a high pressure. When expanded through pistons or turbines, mechanical work is done. The reduced-pressure steam is then condensed, and it is pumped back into the boiler. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. Some practical steam engines discard the low-pressure steam instead of condensing it for reuse.
The idea of using boiling water to produce mechanical motion has a long history, going back about 2,000 years. Early devices were not practical power producers, but more advanced designs producing usable power have become a major source of mechanical power over the last 300 years, beginning with applications for removing water from mines using vacuum engines. Subsequent developments used pressurized steam and converted linear to rotational motion which enabled the powering of a wide range of manufacturing machinery. These engines could be sited anywhere that water and coal or wood fuel could be obtained, whereas previous installations were limited to locations where water wheels or windmills could be used. Significantly, this power source would later be applied to vehicles such as steam tractors and railway locomotives. The steam engine was a critical component of the Industrial Revolution, providing the prime mover for modern mass-production manufacturing methods. Modern steam turbines generate about 90% of the electric power in the United States using a variety of heat sources.[2]
In general usage, the term 'steam engine' can refer to integrated steam plants such as railway steam locomotives and portable engines, or may refer to the machinery alone, as in the beam engineand stationary steam engine. Specialized devices such as steam hammers and steam pile drivers are dependent on steam supplied from a separate boiler.
What else can I help you with?
What type of combustion engine in the steam engine?
A steam engine is an external combustion engine. As the steam engine combusts outside of the engine itself.
How is steam created in a steam engine?
Steam is created in a steam engine by heating water in a boiler until it turns into steam. The steam then builds up pressure, which is used to power the engine and drive machinery.
What was the rotary steam engine?
A rotary steam engine was a fire engine basically
What are steam engines?
noun: an engine worked by steam, typically one in which a sliding piston in a cylinder is moved by the expansive action of the steam generated in a boiler.A steam engine is an external combustion engine. As the steam engine combusts outside of the engine itself.
When was the steam engine improved?
the steam engine was improved in 1769.

Steam
How is steam made in a steam engine?
Steam in a steam engine is made by heating water in a boiler until it turns into steam. The steam is then directed into a cylinder where it pushes a piston, creating mechanical energy that powers the engine.
Why was the steam engine improved and who made the steam engine?
Robert Fulton.
