    Fire Tube Boiler Design Calculation--Zozen

    Fire Tube Boiler Design Calculation. 11-01. Fire tube steam boilers are designed for the purpose of industrial scale heat exchange in order to heat saturated liquid entering the control volume to a saturated gas. Exiting gas leaving the control volume may experience a pressure drop when returning to atmospheric pressure.

    Difference Between Fire Tube Boiler and Water Tube Boiler

    Fire-tube boiler: Fire-tube boiler is those boiler in which the fire or hot gas is present inside the tubes and water surrounds these fire tubes. Since fire is inside the tubes and hence it is named as fire tube boiler. The heat from the hot gases is conducted through the walls of the tube to the water.

    In a water-tube boiler, it contains a minimal amount of water at any given time. It may be just one-tenth the volume of a fire tube boiler, which requires a larger volume of water to act as a heat shield so that metal in the boiler doesn’t melt and create problems. When fire tube boilers run low on water, the metal in the boilers shrinks.
