Boiler performance test programs have been conducted with various objectives including baseline performance characterization, new and retrofit equipment acceptance testing, and combustion and pollution system tuning and optimization. AESPL personnel are highly familiar with ASME test procedures. Some examples of test projects AESPL can take up are:

• Mill Performance in PC fired boilers
  • - Mill fineness – 50, 100, 200m, R-R plots
  • - Fuel distribution – coal pipe flow deviation, % mill output
  • - Fuel-air velocities

• Combustion System Performance in PC, BFB, CFB, Oil & Gas fired and Biomass fired boilers
  • -Furnace exit gas profiles – O2, CO, NO, HVT
  • -Economizer outlet gas profile – O2, CO, NO, CO2, SO2
  • -Particulate loading, LOI, UBC
  • -Fuel and Ash analyses
  • -Thermal efficiency of the system

• Fan Performance in all boiler types

• Air Heater Performance in PC boilers
  • -Inlet & outlet gas & air temperatures
  • -Air heater leakage – Inlet, outlet O2 grid

• ESP Performance
  • -Inlet & outlet velocity & particulate measurement
  • -Particulate collection efficiency determination
  • -Flue gas conditioning system optimization

• Stack Emissions
  • -Particulate emissions
  • -SOx measurement
  • -NOx measurement
  • -CO, CO2 and O2 measurement
