Papermaking Water Tube Boiler

  • Industrial materials for the future R & D strategies : a

    The principal problem addressed by the R & D was the failure of tubes that carry water and steam inside boilers used to recover chemicals during papermaking. These recovery boilers are an essential component of the papermaking process because, in addition to providing recycled chemicals to the wood digester, they also provide a significant

    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.
