Boiler | Engaged in Thermodynamics

The majority of the boilers in the late 1800s and early 1900s were fire tube boilers which operated like water tube boilers except that the hot combustion gases used to heat the water were passed through tubes submerged in water within the boiler. The boilers exploded because they could not be safely pressurized with the existing technology.
