利用热平衡及火用平衡分析来比较带补燃的低温余热发电系统和纯低温余热发电系统，结果表明，补燃降低了排烟损失，提高了余热锅炉效率，因此提高了系统循环热效率。但是在补燃条件下，余热锅炉火用损增大，导致带补燃的低温余热发电系统火用效率要低于纯低温余热发电系统。
利用熱平衡及火用平衡分析來比較帶補燃的低溫餘熱髮電繫統和純低溫餘熱髮電繫統，結果錶明，補燃降低瞭排煙損失，提高瞭餘熱鍋爐效率，因此提高瞭繫統循環熱效率。但是在補燃條件下，餘熱鍋爐火用損增大，導緻帶補燃的低溫餘熱髮電繫統火用效率要低于純低溫餘熱髮電繫統。

In the study, waste heat power generation system with supplementary burner and pure low-temperature waste heat power generation system were compared by thermal balance and exergy bal -ance calculation .The results indicate that the supplementary burner could reduce exhaust loss of waste heat boiler, the Rankine-cycle thermal efficiency was improved as a result , meanwhile, the exergy loss of boiler increased and the exergy efficiency of system decreased .
