从热力学原理出发，研究了高、焦炉煤气混合过程的熵增加和损失。结果表明：高、焦炉煤气混合过程，虽然能量保持不变，但能量品质降低。随着混合比例的增加，混合熵增加和损的变化规律相同，即先增大再减小，且在焦炉煤气体积分数约为48%处达到极大熵增加和损。同时，基于煤气的热力学分析，针对煤气的特性提出了一些合理用能措施。
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.
