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 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 Low calorific value of the fuel Lack of thorough mixing of fuel with air ANSWER DOWNLOAD EXAMIANS APP
