For Closed Systems
: An air vent for steam or a manual valve is required to
discharge the initial air in the steam-using equipment and the condensate
reservoir pipe or any gas generated in the system. For positioning of the air vent
or valve, see [Va] in the closed system drawing on page 9. When releasing the
initial air using a manual valve, leave the valve [Va] slightly open until the
PowerTrap has cycled 2 – 3 times.
(8) Velocity at Outlet Piping
The PowerTrap uses the motive medium supply pressure to push out the
condensate in the trap.
!" The GP10L/GT10L can discharge approximately 6 liters (1.6 U.S. gal) of
condensate for each discharge operation.
!" The amount of time required for each discharge operation will be between 3 and
30 seconds, depending on the back pressure and the motive medium pressure.
This means that the instantaneous flow through the condensate outlet pipe
during the discharge operation is between 0.7 and 7.2 metric tonnes (190 and
1900 U.S. gal) per hour.
!"
When a condensate flowmeter is to be installed in the condensate outlet piping, it
should be selected to reflect the intermittent operation and should be sized to
accommodate the maximum and minimum instantaneous flow.
