### Boiler Efficiency Stack Losses for No.2 Oil

Step 3. Calculate excess air. The value of excess air is not needed for calculation of stack losses but it is the most common parameter of burner performance so it is useful to calculate it for the likely range of O 2 in the flue gas.. The ASME formula for excess air (EA) % by volume when CO is negligible is: EA % by volume = ( 100 x O 2 dry ) / ( 0.2682N 2 - O 2 dry )

Flue Gas Analysis Calculations. Flue gases are formed on combustion of air with fuel in the presence of heat. Combustion of fuel release flue gases which is a mixture of Carbon Dioxide Carbon Monoxide Sulfur Dioxide H 2 O Vapor Nitrogen or Nitro-Oxides Oxygen and ash particles. The quantity of flue gases is also calculated using stoichiometry calculation when air reacts with the fuel.
