Fuels and Combustion In high temperature carbonisation (as compared to low temperature carbonisation) of coal, the Tar yield is more Aromatic content of tar produced is more Ignition temperature of coke produced is less Gas yield is less Tar yield is more Aromatic content of tar produced is more Ignition temperature of coke produced is less Gas yield is less ANSWER DOWNLOAD EXAMIANS APP
Fuels and Combustion Coke oven gas is a better fuel than blast furnace gas, because of its higher Calorific value, cleanliness and relatively low distribution cost (due to its low specific gravity) Heat release rate (thus requiring smaller combustion chamber) Adiabatic flame temperature All of these Calorific value, cleanliness and relatively low distribution cost (due to its low specific gravity) Heat release rate (thus requiring smaller combustion chamber) Adiabatic flame temperature All of these ANSWER DOWNLOAD EXAMIANS APP
