The Differences Between Water Tube Boilers and Fire Tube

How A Fire Tube Boiler Works. A fire tube boiler transfers heat through tubes via thermal conduction, which then heats the water in the container and formulates steam. In other words, the boiler is the pressure vessel that contains the water. These boilers are used in steam or hot water applications when they meet guidelines in ASME Sections I IV. A fire tube boiler can also be used to vaporize liquids other than water as well. Fire tube boilers are ideal for both low and high-pressure steam
