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 oxygen has been used for combustion 21% excess air has been used for combustion Complete combustion of fuel has taken place No excess air has been used for combustion 21% excess oxygen has been used for combustion 21% excess air has been used for combustion Complete combustion of fuel has taken place No excess air has been used for combustion ANSWER DOWNLOAD EXAMIANS APP
Fuels and Combustion Gross and net calorific value of a fuel will be the same Ifits carbon content is very low If its hydrogen/hydrogen compound content is zero If its ash content is zero Under no circumstances Ifits carbon content is very low If its hydrogen/hydrogen compound content is zero If its ash content is zero Under no circumstances ANSWER DOWNLOAD EXAMIANS APP
Fuels and Combustion In general, the limit of inflammability/explosion limit of fuel gases is widened by the Increase in temperature (i.e. preheating) All of these Increase in gas pressure Use of pure oxygen for combustion instead of air Increase in temperature (i.e. preheating) All of these Increase in gas pressure Use of pure oxygen for combustion instead of air ANSWER DOWNLOAD EXAMIANS APP
