Steam engine introduction
A steam engine is a reciprocating power machine that converts the energy of steam into mechanical work. The emergence of the steam engine caused the industrial revolution in the 18th century. Until the beginning of the 20th century, it was still the most important prime mover in the world, and then gradually gave way to internal combustion engines and steam turbines.
Steam engines require a boiler that boils water to produce high-pressure steam. This boiler can use wood, coal, oil or natural gas, or even combustible waste as a heat source. The expansion of steam pushes the piston to do work.
