Stepping Stones for Aiding Operational Excellence at JPL
Initiatives
Root Cause Analysis (RCA), Cross Function Team (CFT) &
Performance Optimisation Group (POG) have been formed
and recommended action points have been followed-up on
Hot air gate replacement with improved design
Adoption of hybrid start-up practice with mini oil guns
Adoption of practice of turbine rolling in Automatic Turbine
Control (ATC) mode
Review of material Purchase Requisition (PR) for its
quality and quantity
Introduction of chimney maintenance ring platform
Fabric filter chamber-wise condition monitoring techniques For measurement of differential pressure and dust concentration in
100% Air Pre-Heater (APH) basket removal and
washing during Manual Overhaul (MOH)
Installation of e-chain system in Stacker Reclaimer-A
Implementation of Cybersecurity Standard ISO 27001:2013
NDCT hot water diversion during winter season
100% Non-Destructive Testing (NDT) during overhauling
Procurement of 1600 horse power (HP) locomotive engine
Benefits
Improved plant reliability, improvement in heat rate, reduction
in Auxiliary Power Consumption (APC) and to avoid repetitive
failures in future
Reduces mill downtime in terms of mill internal cooling
Cold start-up oil consumption brought down by 20 kL (approx.)
Chances of human error during rolling reduced significantly as
manual intervention is eliminated
Inventory optimisation
For internal inspections & rectifications of chimney flue can
titanium liners
Ash Handling Plant (AHP)
Improvement in APH performance in terms of better heat recovery
For protection and life enhancement of cable
To strengthen the security infrastructure of plant Operation
Technology (OT) system
Reduction in condensate dissolved oxygen level which in turn
reduces corrosion rate of pre-boiler circuit
Timely rectification reduces rate of boiler tube leakage
For timely removal of empty rakes and shunting loads during
bunching situations
