gas boiler flue gas production formula

What is Flue Gas? - Keison Products

Typical values in flue gas: Oil burners: 12.5 % - 14 % and gas burners: 8 % - 11 % Water vapour (Humidity) The hydrogen contained in the fuel combines with oxygen to form water (H2O).

Calculate the dry flue gas loss (LDG) using the following formula: LDG = [24 x DG x (FGT CAT)] ÷ HHV where. DG (lb./lb. fuel) = (11CO 2 + 8O 2 + 7N 2) x (C + 0.375S) ÷ 3CO 2 FGT = flue gas temperature ºF CAT = combustion air temperature ºF HHV = higher heating value of fuel Btu/lb. CO 2 and O 2 = percent by volume in the flue gas N 2 = 100 CO 2 O 2

natural gas boiler nitrogen oxide concentration formula

Module 106: Natural gas boiler flue gas recirculation to Natural gas is considered to be one of the cleanest of the commonly used fossil fuels. The emissions from natural gas-fired boilers and furnaces include nitrogen oxides (NOx) carbon monoxide (CO) and carbon dioxide (CO2) and trace amounts of sulfur dioxide (SO2) particulate matter (PM ...

Calculator: Flue Gas Analysis | Thermodyne Boilers

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. You can also refer to Thermodynes Boiler Bible that provides you the general composition of above elements for various fuels.
