Steam engines are typically cooled using a combination of water and air. The steam produced during operation is condensed back into water in a condenser, where it releases heat and is cooled by circulating water, often drawn from a nearby source. Additionally, in some designs, air is used to cool parts of the engine, particularly in the case of smaller or portable steam engines. This cooling process helps maintain optimal operating temperatures and prevents overheating.
The first practical steam-powered 'engine' was a water pump, developed in 1698 by Thomas Savery.
At around age 19 he was working on steam engines.
No, a Stirling engine is not the same as a steam engine. A Stirling engine operates by cyclically heating and cooling a gas, which expands and contracts to produce mechanical work, while a steam engine relies on steam generated from boiling water to create pressure that drives a piston. The key difference lies in their operating principles and the working fluids used. Stirling engines are typically more efficient and can utilize various heat sources, whereas steam engines are specifically designed to use water as the working fluid.
A heat engine is a broad term that encompasses any device that converts thermal energy into mechanical work, utilizing various heat sources and cycles. A steam engine, on the other hand, is a specific type of heat engine that primarily uses steam as its working fluid, typically generated by boiling water. While all steam engines are heat engines, not all heat engines are steam engines, as heat engines can also use gases or other fluids in their operation. The principles of operation may vary based on the type of working fluid and thermodynamic cycle employed.
A steam engine?
A steam engine is a heat engine. A steam engine uses boiling water to produce mechanical work. It uses the steam from the boiling water as its working fluid.
the working fluid for the turbines. usually steam is condensed back to water.

The steam cylinder was heated by steam then cooled to condense the steam. This caused thermal stress and cracking. James Watt corrected that with a separate condenser, allowing the cylinder to remain hot.
When steam is cooled in the air, you can see it condensing into a mist. This process is called condensation.
Condensation and liquid water result from cooling steam.

In the 1780's or 90's American inventor John Fitch build one of the earliest working prototypes of the railroad steam engine.
Richard Trevithick's steam engine was known as the "Puffing Devil." Built in 1801, it was one of the first full-scale working railway steam locomotives. The engine used high-pressure steam to power its movement, showcasing Trevithick's innovative approach to steam power and laying the groundwork for future locomotives.
When steam is cooled in the air it creates water vapor. This water vapor comes together to create clouds and fog.
a device for controlling the rate of working of machinery or for controlling fluid flow, in particular a handle controlling the supply of steam to the cylinders of a steam engine.
