(goodmorning)Morning Report on 09/07/2016
Continue test run Performace Characteristic at load 110-115MW
12 hr Average parameter (17:00-05:00)
Avg. Gross gen 114.84 MW. (since test run 114.16MW)
Min 88.68 MW, Max 125.73 MW.
MST temp 536.5 C (max 541.68)
MST pressure 120.1 bar
MST flow 364.82 t/h
FW flow 353.04 t/h
Oxygen control 3.38%(sp. 3.5%) min 2.05%
Furnace pressure -0.30 kpa. (setpoint -0.30 kpa.)
PA fan load 92/96 A
SA fan load 53.8/54.3 A
ID fan load avg. 163/151 A. (73.4/68%)
Flue gas inlet ESP 174C (Max.179C)
Flue gas outlet ID fan avg. 177.9 C
Metal temp SH3 540-594 C
Metal temp RH 525-574 C
Remark
1. Gross Load reduced to minimum at 88MW during change Livestock fuel pile B1 to A1
2. SA fan current swing reach maximum value 56A many times.
3. For auto mode,
- 3.1 RH spray DSH can't control temperature when load swing
- 3.2 PID CV condensate to Deaerator tank force manual itself 1 time.
- 3.3 For alarm of force auto to manual of FWP still not show.
Main problem.
1. IV #1 had oil leak from servo valve (monitor accum oil tray and cleaning)
2. HP blower A outlet damper can not control. (can not standby) check found micro switch of motor control damaged, now repairing
3. CW Pump C replaced bearing finish. (wait for test run in morning)
4. Thrust bearing temp of FWP B avg. 78.18 C, max 80.6C (minimum flow v. 30%)
5. CV line HPH1 to HPH2 leak, manual valve of HPH2 to dear tank flange leak.
6. HRH steam pipe from IV1,2 to IP turbine leak for 3 pts, we installed a white-red boundary and keep monitor.
