Fuels and Combustion The main drawback of supplying more excess air in the combustion of fuel is the Excessive power requirement of air blower High exit flue gas temperature from the furnace Enhanced sensible heat loss in the flue gas Intermittant and uncontrolled combustion of the fuel Excessive power requirement of air blower High exit flue gas temperature from the furnace Enhanced sensible heat loss in the flue gas Intermittant and uncontrolled combustion of the fuel ANSWER DOWNLOAD EXAMIANS APP
Fuels and Combustion Fuel gases containing hydrocarbons (ie.g. coke oven gas) are not preheated before burning, mainly because It reduces its calorific value tremendously There are chances of explosion during preheating It reduces its flame temperature tremendously The hydrocarbons crack thereby choking and fouling the heat transfer surface by carbon soot It reduces its calorific value tremendously There are chances of explosion during preheating It reduces its flame temperature tremendously The hydrocarbons crack thereby choking and fouling the heat transfer surface by carbon soot ANSWER DOWNLOAD EXAMIANS APP
