Total amount of dry flue gas per 1 kg wood = 4.872 m3. If the concentration in the wet flue gas is required then the water content has to be included in the above calculation. C + O2 = CO2 2H 2 + O2 = 2H 2O Oxygen required for stoichiometric combustion = 4.33+1.6−1.3 = 4.63kg-mol Air requirement = [4.63×100 ×22.41]/= 494.1 m3 at NTP

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.

analyses. The calculated flue gas flow is compared with the reference flue gas flow calculated from the elemental composition. It is shown that, for a wide range of coal and biomass compositions, the above formula performs very well. For light fuel oil the formula is: V God = 1.76435 + 0.20060 H (N) (m 3/kg) and for natural gas: V God
