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 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 Presence of large quantity of hydrogen in the fuel ANSWER DOWNLOAD EXAMIANS APP
Fuels and Combustion For which pair of the fuel gases, calorific value (C.V.) of one fuel is almost double that of the other on volume basis (i.e., kcal/Nm³ ), while the C.V. is same on weight basis (i.e., kcal/kg) ?
