Fuels and Combustion Low temperature oxidation of coal resulting from bad storage conditions does not decrease its Calorific value Caking power Hydrogen content Oxygen content Calorific value Caking power Hydrogen content Oxygen content ANSWER DOWNLOAD EXAMIANS APP
Fuels and Combustion Actual flame temperature is always lower than the adiabatic flame temperature, because there is Neither A nor B Both A & B Always loss of heat from the flame No possibility of obtaining complete combustion at high temperature Neither A nor B Both A & B Always loss of heat from the flame No possibility of obtaining complete combustion at high temperature ANSWER DOWNLOAD EXAMIANS APP
Fuels and Combustion Fuel gases containing hydrocarbons (ie.g. coke oven gas) are not preheated before burning, mainly because The hydrocarbons crack thereby choking and fouling the heat transfer surface by carbon soot It reduces its calorific value tremendously It reduces its flame temperature tremendously There are chances of explosion during preheating The hydrocarbons crack thereby choking and fouling the heat transfer surface by carbon soot It reduces its calorific value tremendously It reduces its flame temperature tremendously There are chances of explosion during preheating ANSWER DOWNLOAD EXAMIANS APP
