  • Water Hammer in Steam and Condensate Systems
    Water Hammer in Steam and Condensate Systems
    Posted in: Engineering guides

    Causes, Risk Points and Engineering Countermeasures Water hammer in steam and condensate systems is one of the most severe operating phenomena that can occur in industrial steam installations. It is not simply pipe noise. It is a mechanical impact load that can stress valves, flanges, steam traps, heat exchangers, supports, pipework and control instruments. In practice, most water hammer incidents in steam systems are related to condensate being present where controlled steam flow is...

  • Steam Dryness Fraction in Steam Distribution Systems
    Steam Dryness Fraction in Steam Distribution Systems
    Posted in: Engineering guides

    Wet Steam, Enthalpy and Steam Separation Steam dryness fraction is used to describe the amount of dry saturated steam contained in a steam-water mixture. In real steam systems, water droplets may be present due to boiler carryover, heat losses in pipework, poor drainage or incorrect pipe sizing. For engineering purposes, steam dryness is not a theoretical parameter. It directly affects available thermal energy, heat transfer, steam trap operation, valve wear and the risk of water hammer.

  • Flash Steam and Heat Recovery
    Flash Steam and Heat Recovery
    Posted in: Engineering guides

    Flash steam is generated when hot condensate at a higher pressure is released to a lower pressure. This typically occurs downstream of steam traps, pressure reduction points, condensate headers or return systems operating at a lower pressure than the steam-consuming equipment. In terms of thermodynamic properties, flash steam is not different from saturated steam. The term describes the way it is generated: it is not produced in the boiler, but results from pressure reduction of hot...

  • Expansion of Pipes in Steam Systems
    Expansion of Pipes in Steam Systems
    Posted in: Engineering guides

    In steam and hot fluid systems, pipe length increases as temperature rises. Thermal expansion must be considered during system design in order to avoid high mechanical stresses, excessive loads on fixed points, pipe deformation and forces transmitted to valves, flanges, steam traps, heat exchangers and other equipment. Proper arrangement of pipe guides, supports, fixed points and expansion joints allows the pipework to move in a controlled manner and absorb the change in length caused by...

  • Calculating Flash Steam
    Calculating Flash Steam
    Posted in: Engineering guides

    Flash steam is generated when hot condensate at a higher pressure is released to a lower pressure. The pressure reduction lowers the saturation temperature, and part of the heat contained in the condensate is converted into steam. This phenomenon commonly occurs downstream of steam traps, pressure reducing points, condensate return lines and flash vessels. Correct estimation of flash steam quantity is important for sizing condensate lines, flash vessels, vents and energy recovery systems.
