Mass of Carbon in Flue Gases

The mass of carbon, contained in 1 kg of flue or exhaust gases, may be calculated from the mass of carbon dioxide and carbon monoxide present in them.

We know that 1 kg of carbon produces 11 / 3 kg of carbon dioxide. Hence 1 kg of carbon dioxide will contain 3 / 11 kg of carbon. Also 1 kg of carbon produces 7 / 3 kg of carbon monoxide, hence 1 kg of carbon monoxide will contain 3 / 7 kg of carbon.

Mass of carbon per kg of flue gas is given by:
