Fuels and Combustion Ignition temperature decreases progressively from anthracite to lignite, because Volatile matter content increases Ash content increases Carbon content decreases Moisture content increases Volatile matter content increases Ash content increases Carbon content decreases Moisture content increases ANSWER DOWNLOAD EXAMIANS APP
Fuels and Combustion If oxygen content in the flue gas rises too high, fuel is being wasted by Incomplete combustion None of these Moisture loss Dry gas/stack gas loss Incomplete combustion None of these Moisture loss Dry gas/stack gas loss ANSWER DOWNLOAD EXAMIANS APP
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 Lack of thorough mixing of fuel with air Presence of large quantity of hydrogen in the fuel Low calorific value of the fuel High sulphur content in the fuel Lack of thorough mixing of fuel with air Presence of large quantity of hydrogen in the fuel Low calorific value of the fuel High sulphur content in the fuel ANSWER DOWNLOAD EXAMIANS APP
