Combustion of Fuels - Carbon Dioxide Emission

Deze pagina vertalen

To calculate the Carbon Dioxide - CO 2 - emission from a fuel, the carbon content of the fuel must be multiplied with the ratio of molecular weight of CO 2 (44) to the molecular weight of Carbon (12) -> 44 / 12 = 3.7. Carbon Dioxide emission from burning a fuel can be calculated as. q CO2 = c f / h f M CO2 /M m [1]. where. q CO2 = specific CO 2 emission [kg CO2 /kWh]
