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 It reduces its flame temperature tremendously The hydrocarbons crack thereby choking and fouling the heat transfer surface by carbon soot There are chances of explosion during preheating It reduces its calorific value tremendously It reduces its flame temperature tremendously The hydrocarbons crack thereby choking and fouling the heat transfer surface by carbon soot There are chances of explosion during preheating ANSWER DOWNLOAD EXAMIANS APP
