Fuels and Combustion A liquid/gaseous fuel containing hydrocarbons and high amount of sulphur is burnt with 40% excess air. The flue gas still contains large amount of carbon monoxide. This may be due to the Low calorific value of the fuel Lack of thorough mixing of fuel with air Presence of large quantity of hydrogen in the fuel High sulphur content in the fuel Low calorific value of the fuel Lack of thorough mixing of fuel with air Presence of large quantity of hydrogen in the fuel High sulphur content in the fuel ANSWER DOWNLOAD EXAMIANS APP
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 No excess air has been used for combustion 21% excess oxygen has been used for combustion Complete combustion of fuel has taken place 21% excess air has been used for combustion No excess air has been used for combustion 21% excess oxygen has been used for combustion Complete combustion of fuel has taken place ANSWER DOWNLOAD EXAMIANS APP
