C. Condensate outlet piping
Make sure to pipe the discharged condensate to a
safe area such as a pit.
(1) The temperature of steam condensate
discharged from the unit exceeds 100
C. Do not
use PVC or lead piping intended for water
supply.
(2) The sound of steam flashing (a small pinging
sound) may occur from the opening of the condensate outlet piping. To
reduce the sound, extend the condensate outlet piping by 3 m or more.
(3) When the PowerTrap (No. 1) pumps the condensate, it is discharged
vigorously from the condensate outlet piping. When the end of the
piping is open to the atmosphere, take safety measures such as
installing a cover so that there is no burn caused by condensate
splashing, and no influence on components.
(4) When the condensate recovery piping installed after the condensate
outlet piping has a pipe rise, make sure to install a valve after the unit.
This enables easier maintenance work for the internal components in
the unit such as the PowerTrap and prevents backflow from the
condensate outlet piping.
(5) The diameter of the condensate piping installed after the unit must be
designed and selected to accommodate two phase flow. (The
condensate piping diameter must be larger than the diameter of the
unit outlet.)
D. Condensate blow piping
Make sure to pipe the discharged condensate to a safe area
such as a pit.
Condensate in the PowerTrap must be discharged to
prevent freezing or corrosion when the unit is shut down for
a long period of time.
The piping should not have any pipe rise after this valve as
the condensate needs to be discharged naturally (by
gravity).
