How a steam boiler works | Viessmann

The way a steam engine works is extremely similar to a steam boiler. Instead of gas coal was applied to a fire to produce lots of heat. A boiler full of water was located just behind the fire so the water would eventually heat and evaporate. This would rise and follow a pipe system into a cylinder. Within the cylinder there was a piston.
