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