F. Verify that the boiler hydrostatic test (if performed) was acceptable and no other

problems are apparent, that safety valve gags have been removed, steam lines drained,

and drum level is at minus one (1) on the drum sightglass or Yarway.

G. Verify that the Boiler Pins have been removed from the hangers at the top of the HeatRecovery Area (HRA) and the (INTREX). Refer to section 1, step 5.

bed material was removed, 150 tons will be required. If only J-Valve and INTREX bed

material was removed, approximately 50 tons will be required.

General Operational Guidelines

In the event that major changes in Unit control setpoints are made, equipment is started or shut

down, or unstable operations exist just prior to or at shift change, the off-going shift Control

Operator Supervisor (COS) and appropriate Operators shall stay and work with the oncoming

shift, until the initiated changes are well in hand, Unit operation has totally stabilized, and the on-

coming shift is fully aware of all aspects of changes and/or root causes.

Maintain Electronic Log and Turnover Log for oncoming shift as record of changes/unstable

conditions.

A hard copy of this Startup Procedure is to be printed out and maintained on the console at all

times during unit cold startup.

As each prerequisite and numbered startup step is verified appropriate Control Operator

Supervisor (COS) shall confirm action by initial and time. Mark-up any missing, incomplete or

erroneous startup instructions. Completed procedure shall, at conclusion of startup, be routed to

Production Superintendent and IRI Operations Manager for information and/or review.

c. Once bed temperature is stabilizes place the ISH air controller in Auto with a set

point of 20 kpph.

d. Monitor the bed temperature and if stable prepare to place FSH air controller in

service.

e. Manually open FSH air controller while monitoring bed temperature. Continue to

open controller until FSH airflow is about 18 to 20 kpph. This should take about 30

minutes to complete.

f. Once bed temperature is stabilized place the FSH air controller in Auto with a setpoint of 20 kpph.

g. Bed temperature may momentarily decrease. You will have to add coke to get bed

temperature under control.

h. Take Induct Burners out of service at about 40 to 50 MWs and line up for back up.

i. Reset Inducts and Purge.

____11. After INTEX is p laced in service, place hot w ell make-up pump in service and l ine

up to condenser sprays

____12. At approximately 60 MWs place second Circulating Water Pump in service

a. Verify megalert in safe range

b. Verify cooling tower at adequate level

c. START pump

d. Verify discharge valve opened

____13. At approximately 60 to 80 MWs place Boiler Feed Booster Pump (BFBP) in

service.

a. START the BFBP Auxiliary lube oil pump. (It should already be running).

b. Verify motor meggared and in safe range.

c. Following valves should be lined up:

d. Pump Suction - OPEN

e. Pump Discharge MOV - OPEN

f. Warm-up valve Three (3) rounds OPEN

g. Recirculation Block Valves - OPEN

h. Verify pump drains are closed.

i. Verify oil reservoir has adequate level.

j. Verify cooling water lined up to seals and oil coolers.

k. Line up the air supply to the Recirculation Flow Controller valve. Make sure the

Recirc. Valve has a closed indication and is not leaking through.

l. The BFBP should already be warmed.

m. Select BFBP to be placed in service

n. Select START target and enter

o. Monitor motor amps and vibration until pump is stabilized

p. The Auxiliary lube oil pump will shut down if oil pressure is adequate.

q. Place stand-by BFBP in remote AUTO.

____14. RH/SH pass dampers

e. Put SH pass damper to 100 percent open

f. Slowly open RH pass damper to 50 percent open. Manually adjust reheat sprays

as required to maintain temperature below 1008 degrees Fahrenheit.g. Automate RH and SH sprays when temperatures reach 950 degrees Fahrenheit

with set points of 1008 degrees.

h. Adjust ISH and FSH splits so that ISH has 70 percent of the SH flow and FSH has

approximately 30 percent of the flow.



35/51


____15. At approximately 100 to 110 MWs, indiv idual ly inspect all six (6) governor valves

and verify 100 percent open. Communicate if any valves not 100 percent open

and ensure a work request is w ritten.

____16. Place Sand Feeder in service and resume scheduled sand inject ion schedule.

____17. Place Stripper Coolers in Service. Test run both RALs for proper operation.

____18. Put Expor t Steam in service.

a. Hot Reheat pressure at 500 psiq.

b. Check all associated block valves in export steam to be lined up.

c. Open MOV and adjust so both units are sharing export steam.

____19. Perform a detai led walkdown of the old side and new side to ver if y al l

appropriate drain /blowdown valves are properly blocked and not leaking

through. Ensure a work request is written for any leaking valves.

____20. Check the DCS for Disabled and Inactive Alarms.

Note: It is very important to check the DCS for Disabled and Inactive Alarms.

a. Return all alarms to normal conditions.

b. Write Work Requests for all alarms not working, stating associated problem(s).
