Fuels and Combustion A coal having high volatile matter content will Have a very high calorific value None of these Give less yield of tar and gas on carbonisation Burn with a small non-smoky flame Have a very high calorific value None of these Give less yield of tar and gas on carbonisation Burn with a small non-smoky flame ANSWER DOWNLOAD EXAMIANS APP
Fuels and Combustion Height of coke oven is limited (say maximum upto 7 metres) mainly by the Problem in door cleaning Structural strength of silica bricks Buckling of ram of pusher car at the time of coke pushing Problem of uniform heating along its height Problem in door cleaning Structural strength of silica bricks Buckling of ram of pusher car at the time of coke pushing Problem of uniform heating along its height 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 There are chances of explosion during preheating It reduces its flame temperature tremendously It reduces its calorific value 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 flame temperature tremendously It reduces its calorific value tremendously ANSWER DOWNLOAD EXAMIANS APP
