Boilers

Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure

Water Tube vs Fire Tube - Patterson-Kelley

Water Tube vs Fire Tube. Water Tube. Advantages. The water volume in a water-tube boiler is significantly less than what would be present in a fire tube boiler. This means that there is faster response available to adapt to varying temperature conditions, i.e. swing loads. To be noted, this accounts for wider capabilities in output ranges as well.
