1.0 Purpose

1.1 This procedure provides direction for safe, reliable and efficient unit

start

- up . This procedure shall be use for Cold Start

- Up

1.2 As the steps or operations are completed on each page the

operator completing or directing the completion shall initial in the

space provided at the bottom of each page. If the page is not

completed by the same operator the operator turning over the

procedure shall initial next to the last step completed.

1.3 Once this procedure and the milestone have bee n completed it

shall be routed to the day shift PTL through the on shift PTL

.

2.0 Limits and Precautions

2.1 Limits

Steam Turbine First Stage Metal OR Reheat Bow l I nner

M etal temperature s is Less than 400 O F

2.1.3 Warm Start

- Up procedure SHALL be followed when the

Steam Turbine First Stage Metal O R Reheat Bow l Inner

Metal temperatures are Greater than 400 O F but Less than

700 O F.

2.1.4 Hot Start

2.2 Precautio ns

2.2.1 This procedure attempts to but will not cover all possible

conditions that may be encountered during Start

- Up . If

conditions arise that will cause deviations from the

procedure the Operations PTL MUST be notified PRIOR to

the deviation . The only exception to receiving PRIOR

approval is in the event of an emergency situation. In this

case the Operations PTL: MUST be notified as soon as the

condition is stable.

3.0 Perform Control Room Preliminary Checks

3 .1 At the DCS “U1_OVRVW” REPORTS Run Bloc ks in Manual report

Note: Some blocks may be left in manual due to equipment or DCS tuning

problems. The Operations PTL must review and approve blocks to be left

in manual.

3.1.1 Return blocks reported in Manual to Automatic except those

approved by the Operations PTL to be left in manual

3.2 At the DCS “U1_OVRVW” REPORTS Run Inhibited Alarm report

Note: Some alarms may be left inhibited due to equipment or DCS tuning

problems. The Operations PTL must review and approve alarms to be

inhibited

3.2.1 R eturn inhibited alarms to active status except for those

approved by the Operations PTL to remain inhibited

3. 3 Ensure all 4160V Buss and 480V Load centers are normal. Verify

all 4160V motors have been meggared. Any switching has been

complete or switchin g written and ready to be assigned.March 13, 2007

- Up Procedure

16.19 At DCS “IP STEAM” page check/place the HRH steam by

- pass

valve in AUTO/REMOTE

16.20 At the DCS “ IP DRUM” page Select and Close the IP Superhe ater

Drain AOV 1660.

16.21 Once the GT has reached Mode 6Q for one minute observe the

ammonia Flow Control will start injecting to control the NOx to

1.5ppm

16.22 At the CEMS computer perform a MANUAL Calibra tion on the

appropriate GT once NOx is below 2.5ppm and stable . Calibration

takes approximately 28 minutes to complete. After Calibration is

complete verify that there are no CEMS faults and the GT has been

calibrated correctly. Refer to procedure K

- 200 (I nitiating a Manual

Calibration with CEM Computer)

16.23 At the DCS from the “LP Drum” page, once the steam temperature

and pressure difference between the in service HRSG and the

HRSG on coming is equal to or less than 200 ° F and 25psig open

the LPSH MOV

- 1050

16.24 At the DCS “LP DRUM” Select and Close LP Superheater Drain

AOV 1970

16.25 At the DCS from the “Auxiliary Steam” page, once the difference

between the in service HRSG IP Drum pressure and IPSH

temperature are within 25°F and 50psig, open the A ux Steam

MOV

16.26 Verify all bypasses (HP/ HRH/ LP) closed.

16.27 Place the GT in external load and control load via the ULD.March 13, 2007
