List Out The Data Required For Calculation Of Boiler Efficiency Using ‘indirect Method’?

Answer»

The data required for CALCULATION of boiler efficiency using indirect method are:

  • Ultimate analysis of fuel (H2, O2, S, C, MOISTURE content, ash content)
  • Percentage of OXYGEN or CO2 in the flue gas
  • Flue gas TEMPERATURE in 0C (Tf)
  • Ambient temperature in 0C (Ta) & humidity of air in kg/kg of dry air.
  • GCV of fuel in kcal/kg
  • Percentage combustible in ash (in case of solid fuels)
  • GCV of ash in kcal/kg (in case of solid fuels)
