Boilers - How Steam Engines Work | HowStuffWorks

How Steam Engines Work. A fire-tube boiler was more common in the 1800s. It consists of a tank of water perforated with pipes. The hot gases from a coal or wood fire run through the pipes to heat the water in the tank, as shown here: In a fire-tube boiler, the entire tank is under pressure, so if the tank bursts it creates a major explosion.
