Utility Boiler
"Predictive Maintenance"

Advanced Predictive Maintenance has been introduced for utility boiler in Malaysia. The system comprises combination of on-line monitoring system realizing of “Visualization of life” and off-line inspection to accomplish more precise life assessment.

OBJECTIVE

  • To optimize the preventive maintenance for boiler critical parts
  • To realize unit availability higher

METHOD

  • Combination of On-line monitoring and Off-line inspection
  • Real time trend & machine condition analysis (temperature, stress)
  • Higher grade off-line analysis (Advanced UT scale measure, replica analysis, etc.)

ADVANTAGES

  • Achieve the maintenance work economically
  • Achieve unit higher availability
  • Minimize the unforeseen outage
  • Efficient planning & budgeting for maintenance work
CONCEPT
CRITICAL PARTS
Critical Parts Selection Criteria

The selection is according to past unit experiences which caused unit shut-down or load reduction case of parts malfunction

Monitoring Subject
  • To assess creep life of tubes
  • To grasp repair timing
  • To evaluate air leakage
