Fuels and Combustion Beehive coke oven Facilitates by-products recovery Produces coke with very poor strength Gives larger yield of coke (around 85%) as compared to by-product ovens Takes 2-3 days for coking of coal but requires no external fuel for heating Facilitates by-products recovery Produces coke with very poor strength Gives larger yield of coke (around 85%) as compared to by-product ovens Takes 2-3 days for coking of coal but requires no external fuel for heating 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 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 It reduces its calorific value tremendously ANSWER DOWNLOAD EXAMIANS APP
