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 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 ANSWER DOWNLOAD EXAMIANS APP
