Guidelines for UCE

Guidelines for UCE:

UCE has to check the following at the beginning of the shift:

  • Status of Mills, ID fan, FD Fan and PA fans.
  • Status of all the unit Protections.
  • Ensure availability of emergency equipments (only in morning shift) & for any defects concerned maintenance & DGM(O) is to be informed.
  • Follow changeover schedule & for any defects concerned maintenance & DGM (O) is to be informed.
  • Coal Bunker levels.
  • ESP fields in service
  • Auto loops in service.
  • Boiler metal temperatures.
  • Grid Frequency.
  • Unit Generation.
  • Boiler water chemistry parameters.
  • Availability of operators at different location.
  • Communication system.
  • Equipments under PTW.
Normal Operation
  • During the shift UCE has to monitor parameters deviations as indicated by the Annunciation window and if required instruct the Desk Engineers to take Corrective actions as per the –
  1. Boiler operation  manuals    
  2. Turbine operation manuals  
  3. Generator operation manual 
  • He registers Defects, as reported by desk Engineers or local Operators, to concerned Maintenance Department through SAP notification.
  • He ensures availability of the equipments after Return / cancellation of PTWs.
  • He has to instruct Desk engineer to modulate the Unit Load as per schedule in co-ordination with the Shift Charge Engineer.
  • UCE takes a round to different locations of the Unit to check any abnormality in the Unit i.e. Steam leakage, Coal leakages, safety arrangements etc.
  • In case of total Station out he has to act as per the instruction available in the unit “Station Power Failure Operation.”
  • In case of Fire, as indicated by the Fire alarm, he communicates immediately to Fire Station (Located inside the Plant) and also SCE.
  • In case  of Hydrogen Gas Leakage as indicated  by the H2 Pr. drop rate  UCE has to check the followings---
  • H2 – Seal oil Diff Pr.
    1. Seal Oil filter Diff. Pr.
    2. Possibility of H2 Leakage.
    3. Check the leakage using Hydrogen Leak Detector.
    4. Concentration of H2 leakage should not be allowed to go beyond the fire hazard limit (84 %, though explosive mixture is between 4 - 75 %).
    5. In case of sharp drop in Gen H2 Pressure UCE has to trip the Turbine manually and instruct local operator to start CO2 purging.UCE has to instruct the Desk Engineers and local operators to perform daily routine activity

HP & LP Bypass Operation and Protection

Image
HP & LP Bypass Operation and Protection Purpose Boiler operation independent of the turbine Minimum steam flow through SH & RH tubes during start-ups, low load operation & sudden unloading of unit Utilized or building up of steam parameters Avoiding the boiler trip on Reheat protection No steam flow through Boiler steam tubes will lead to starvation & thereby overheating and lead to premature failure of tubes  The capacity of HPLP bypass is 60% of full load turbine steam flow  Reheat Protection: RH protection (delay=10 sec) will act if TURBINE HP V/V & HPBP CLOSED [ either turbine HP stop v/v or HP CV in both HP line closed ] & [ both HP BP <2%]             OR TURBINE IP V/V & LP BP closed [ Either IP stop v/v or IP CV v/v in both IP line closed ] & [ Either LP BP stop v/v or LP BP C/V in both LP line is closed] OR   Generator ckt bkr open & [both HP BP closed OR both L...

Generator Air Tightness Test

Generator Air Tightness Test Period Of Test= 24 Hrs without a Break Air Pressure Drop (Allowed in 24 Hrs) : <=0.15 ksc Air Test Pressure = 3.5 ksc All LLDs Drain Closed. Ensure Seal Oil system in Operation Seal Oil DP >1.5 ksc AS Seal Oil Pr>4.5 ksc, start H2S Seal Oil system H2 Cooler Isolated PW in Winding is in filled condition, Winding Isolated. PW also kept Isolated. PW Tank at Atmospheric Pressure Ensure availability of  Instrument air and Bleed Out moisture from it by keeping it open till  Connect flexible air hose with the gas plant through the coupling and ensure no air leakage is there  The filling is to be done by opening the valves in the normal H2 filling line where as the valve from H2 rack side will remain closed. Once the air filling is commenced the test record data sheet   The air valve is to be opened full. While pressurising the LLD / Seal oil DP / Seal oil parameters are to be recorded as per the enclosed sheet. The...
