Boilers - University of Alabama

Water-Tube Boiler (1867) A water-tube boiler is one in which the products of combustion pass around the outside and heat tubes containing the water. The water tube diameter is much smaller than the shell diameter of a fire-tube boiler, so much higher pressures can be obtained, well over 2000 psi. The furnace and boiler tube area must be
