    Figure 2.3 Water Tube Boiler: Water tube or "water in tube" boilers in which the conditions are reversed with the water passing through the tubes and the hot gasses passing outside the tubes (see figure 2.3). These boilers can be of single- or multiple-drum type. These boilers can be built to any steam capacities and pressures, and have higher efficiencies than fire tube boilers.Learn More

  • Steam System Balancing for Multifamily Existing Buildings

    The size of the boiler outlet and the design of the near boiler piping (also known as the header piping) also have a big impact on steam quality. If the steam outlet is too small, the high exit velocity of the steam will carry water droplets along with it — hence the benefit of limiting high fire as discussed above.Learn More

  • Shell Boilers | Spirax Sarco

    For any one boiler, if the heat transfer rate (q_dot - body text.jpg) is increased, the maximum allowable boiler pressure is reduced. A compromise is reached with a furnace tube wall thickness of between 18 mm and 20 mm. This translates to a practical pressure limit for shell boilers of around 27 bar.Learn More
