LNG Steam Simulator Exercise

015. Run the Simulator to Start Condensate Extraction

[Load Snapshot "Ex_015_Changing Over from DO to HFO_Burning"]

- Asssume scenario as described below [but check to confirm] and then follow the given procedures

Electrical Power:-

Shore Power:Off; Emergency Generator:Auto Stand-by; Turbo Generators:One on load and the other off; Diesel Generator:On Load

Deaerator:-

Full with guage glass reading between 60~70 mm

Both Boilers:-

Both Boiler Press - aboout 6 Mpa; Both boilers are running on HFO supply.

Distilled Water Tank (DWT) & Atmospheric Drain Tank (ADT):-

Both DWT & ADT about 60% full.

>> Procedure to prepare the Condensate System:-

Emerg Distrib:
1 Close the Condensate Pump 1 Breaker
Main Distrib:
2 Close the Condensate Pump 2 Breaker
Condensate:
3 The Condensate Pumps will loose suction and may cavitate if the Hotwell Level is low. For this reason, check Hotwell water level is at least +1 inch (25mm). If necessary, fill up by opening the valve from the DFT to the Hotwell (via the main condenser) until level is satisfactory then close the valve.
4 Open Condensate Pump 1 suction vent valve (needed to obtainsuction on the pump).
5 Open Condensate Pump 1 suction and discharge valves.
6 Open Condensate Pump 2 suction vent valve.
7 Open Condensate Pump 2 suction and discharge valves.
8 Open the condensate recirculationregulator inlet and outlet cutout valves.
9 Close the condensate recirculation regulator bypass valve.
10 Start Condensate pump #1 and wait for the Condensate pump Pressure low Alarm to clear.
11 Put Condensate pump 2 into standby.
