  • Water-tube or fire-tube condensing - Hot Water Boilers

    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 beLearn More

  • Operation of water tube boilers explained - Bright Hub

    Water-tube boilers differ from shell type boilers in that the water is circulated inside the tubes, with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1), it is easy to see that because the tube diameter is significantly smaller, much higher pressures can be tolerated for the same stress.Learn More
