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 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 The hydrocarbons crack thereby choking and fouling the heat transfer surface by carbon soot ANSWER DOWNLOAD EXAMIANS APP
