1. Start Bottom Ash Handling (BAH)
- Level BAH column overflow
- Start pump 6P-4033-JA or B.. (To be overflowed)...
2. Start Gas Air Heater (GAH)
- Lube oil GAH auto mode...
3. Persiapan start IDF & FDF
- Yakinkan inlet damper IDF & FDF fully close..
- Posisi LCP remote..
- IDF damper mode : AUTO --> 0% open..
- FDF damper mode : CASCADE --> 0% open..
- Overfire damper : CASCADE --> 0% open..
- Secondary air damper : AUTO --> 0% open..
- Bypass coal gate (core air) --> AUTO --> 0% open..
- Economizer outlet damper : Posisi manual --> 100% open..
- Bypass economizer : manual --> 100% open..
- Solenoid bypass 100% (auto open)..
4. Ensure condition "OPEN"..
- MOV-2113 (venting steam drum)..
- MOV-2122
- MOV-2124
- MOV-2125
- MOV-2131
- MOV-2132
5. Start IDF, make sure IDF full speed and indikasi arus di DCs normal..
6. Start FDF, ketika flow FDF menuju 5 kNm3/h, IDF damper mulai operasi..
- Monitoring press P21A. 2461 (SP - 20 mmWC).
- Overfire damper open 100%..
- Secondary damper open 100%..
7. - Ketika flow combustion air >= 67.3 kNm3/h --> purge permit..
- Ketika flow combustion air >= 75 kNm3/h --> purge progress release 300 s.. (Indikasi DCS hijau)..
8. Leak check sequence
- Start LFO transfer pump 6P-4003 JA/B; SP = 22 kg/cm2..
- Start LFO leak check
- Setelah leak check, MFT reset..
Kondisi MFT reset: Overfire damper 25% open, Secondary air damper 30% open.
9. Start IAF..
10. Manualkan FDF damper --> naikkan flow menuju 90 kNm3/h..
11. Start burner (A1 --> B4), Ignition Igniter Sequence, Igniter Burner Sequence, Extraction Sequence..
