Diameter Of Tube For Water Tube Boilers

  • Water for the Boiler | Spirax Sarco

    Water-tube boilers have a limited water surface area in the steam drum, relative to the evaporation rate. This results in very high steam release rates per unit of water area, and turbulence. Water-tube boilers tend to be higher rated, perhaps over 1 000 tonnes/h of steam.

  • Spiral watertube boiler - Wikipedia

    Spiral water-tube boilers are a family of vertical water-tube boilers. Their steam generating tubes are narrow spiral tubes, arranged in circular fashion around a central vertical water drum. The water tubes are long, numerous and of 2 inches (50 mm) diameter, or smaller. This gives an extremely large heating area, and so good steam raising

    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. Water-tube boilers are used in power station applications that require: A high steam output (up to 500 kg/s).
