                              Flue Gas Analysis Calculations<\/h2>\n

                              Flue gases are formed on the combustion<\/a> 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, H2<\/sub>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.<\/p>\n

                              You can also refer to Thermodyne\u2019s Boiler Bible<\/strong><\/a> which provides you with the general composition of the above elements for various fuels.<\/p>\n

                              The calculator below helps you determine the number of flue gases<\/strong> generated per Kg of fuel by providing the elemental composition of the fuel and its mass faction.<\/p>\n
