Abstract Based on thermodynamic principles, entropy generation and exergy loss of BFG (Blast Furnace Gas) and COG (Coke Oven Gas) during mixing were studied. The results indicated that although the quantity of energy is maintained,but the quality of the energy is degraded during mixing. The entropy generation and the exergy loss vary similarily with the change of mixing ratio,they first increased then decreased and both reached a maximum at a fraction of COG around 48%.Some measurements for rational energy utilization are proposed.
