Fuels and Combustion A coal with high ash content Is harder and stronger Is not subjected to washing Has low quantity of mineral matter Has higher calorific value Is harder and stronger Is not subjected to washing Has low quantity of mineral matter Has higher calorific value 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 flame temperature tremendously There are chances of explosion during preheating It reduces its calorific value tremendously The hydrocarbons crack thereby choking and fouling the heat transfer surface by carbon soot It reduces its flame temperature tremendously There are chances of explosion during preheating It reduces its calorific value tremendously The hydrocarbons crack thereby choking and fouling the heat transfer surface by carbon soot ANSWER DOWNLOAD EXAMIANS APP
