Assuming that flue gases contain only these two gases, the losses [kW]can be calculated as: φ L1 = m& CO ⋅ H l,CO + m& H 2 ⋅ H l, H 2 (9) where m& CO is the mass flow of carbon monoxide [kg/s], m& H 2 the mass flow of hydrogen, H l,CO the lower heating value (LHV) of carbon monoxide (10,12 MJ/kg), and H l,H 2 the lower heating value (LHV) of hydrogen (119,5 MJ/kg).

Typical flue gases from natural gas-fired power plants may contain 8-10% CO 2, 18-20% H 2 O, 2-3% O 2, and 67-72% N 2; typical flue gases from coal-fired boilers may contain 12-14 vol% CO 2, 8-10 vol% H 2 O, 3-5 vol % O 2 and 72-77% N 2.

Wood Granulated: e = 30%. the flue gas flow rate will be estimated by the formula: With flue mass flow : [kg/h], e:% excess air, P :Power burner [th/h] /PCI. As you have probably noticed the flue gas flow rate is given here in mass flow, to convert in volume flow, we need to know the average density of flue gas.
