Fuels and Combustion Too much of excess air in combustion results in high Percentage of oxygen in flue gases Fuel consumption for the same heat load All of these Stack gas temperature Percentage of oxygen in flue gases Fuel consumption for the same heat load All of these Stack gas temperature ANSWER DOWNLOAD EXAMIANS APP
Fuels and Combustion The main drawback of supplying more excess air in the combustion of fuel is the High exit flue gas temperature from the furnace Enhanced sensible heat loss in the flue gas Excessive power requirement of air blower Intermittant and uncontrolled combustion of the fuel High exit flue gas temperature from the furnace Enhanced sensible heat loss in the flue gas Excessive power requirement of air blower Intermittant and uncontrolled combustion of the fuel ANSWER DOWNLOAD EXAMIANS APP
