  • Power plant and calculations: Why does Boilers main steam

    Apr 10, 2021 · 2-Load on Boilers is more than design. Main steam temperature increases if the steam generation is more than actual designed. 3-Leakage in super heater (SH) coils. If there is any leakages in SH coils, steam flow to SH coil decreases & hence main steam temperature increases. 4-Choking in Super heater coils.

  • Boiler Efficiency and Steam Quality: The Challenge of

    This steam trap is therefore acting mostly as a "steam cooler" wasting steam from the Steam Main. Note the nice insulation job however; this is probably keeping the problem from being much worse. Condensate should always be drained from the BOTTOM of the steam line in low sections of pipe and at changes in direction, such as a 90 Degree turn.

  • PSV outlet piping to atmosphere design pressure? - Safety

    Mar 03, 2015 · Hi, I believe that outlet pipe should have design pressure same as the boiler design pressure and have been defending that at my work. However, people at my work argument that since outlet pipe discharge to atmosphere, piping design pressure can be low(5K Class), since pressure over all the length of outlet will be {atmosphere + the pressure loss trough pipe}.
