Fuels and Combustion Beehive coke oven 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 Takes 2-3 days for coking of coal but requires no external fuel for heating Produces coke with very poor strength ANSWER DOWNLOAD EXAMIANS APP
Fuels and Combustion A liquid/gaseous fuel containing hydrocarbons and high amount of sulphur is burnt with 40% excess air. The flue gas still contains large amount of carbon monoxide. This may be due to the High sulphur content in the fuel Presence of large quantity of hydrogen in the fuel Low calorific value of the fuel Lack of thorough mixing of fuel with air High sulphur content in the fuel Presence of large quantity of hydrogen in the fuel Low calorific value of the fuel Lack of thorough mixing of fuel with air ANSWER DOWNLOAD EXAMIANS APP
