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)
Adiabatic flame temperature
All of these
Heat release rate (thus requiring smaller combustion chamber)

Fuels and Combustion
With increase in the temperature of carbonisation of coal

Calorific value of the coke oven gas decreases due to cracking of hydrocarbons which is not compensated by increase in CO & H? content
Hydrogen content of coke oven gas increases due to cracking of hydrocarbons
Methane content in the coke oven gas decreases and carbon monoxide content increases
All of these
