Equipment Performance Studies

Boilers Efficiency & Performance

The studies involve carrying out possible measurements to determine boiler efficiency by indirect method as well as the heat and mass balance computations to estimate the useful heat and to assess operating efficiency.

The typical scope of the work covers
  • Measuring Oxygen, Carbon Mono-Oxide & Temperature Contents in flue gas at Air Preheater/ Economizer outlet
  • Measuring Oxygen Contents in flue gas at outlet of APH & inlet of ID Fan.
  • Noting down surface temperature and area for the boiler system (up to APH outlet)
  • Computing surface heat loss for the boiler system
  • Analyzing heat loss through unburnt contents in ash based on inhouse data
  • Analyzing feed water quality
  • Studying the blow down practices
  • Computing Combustion Efficiency of the boiler, based on the inhouse fuel properties
  • Estimating air ingress in Air Preheater, Bag Filter / Electrostatic Precipitator (ESP)
  • Assessing the performance and suggesting ways for improvement, as applicable
  • Submitting the report

  • A team of one engineer is deputed to carry out the studies and furnishing the report. The field visit is typically for 5 to 6 hours; during which up to 4 measurements can be carried out depending upon initial preparations, conditions of motors and cabling systems and support from the plant team.
