Fuels and Combustion A carbonaceous fuel (containing no H₂ or hydrocarbons) is burnt and the resulting flue gas contains 21% CO₂. It means that 21% excess air has been used for combustion 21% excess oxygen has been used for combustion No excess air has been used for combustion Complete combustion of fuel has taken place 21% excess air has been used for combustion 21% excess oxygen has been used for combustion No excess air has been used for combustion Complete combustion of fuel has taken place ANSWER DOWNLOAD EXAMIANS APP
