通过正反平衡两种方法对锅炉进行能效测试。分析了运行过程中过量空气系数、烟气中氧气含量、 CO含量和排烟温度的变化，从燃烧和换热状况分析锅炉运行中热损失的原因。计算得到锅炉正平衡和反平衡的效率分别为73．04％和74．90％，平均效率为73．89％，并提出改善锅炉能效的整改方案以提高锅炉热量利用效率。
通過正反平衡兩種方法對鍋爐進行能效測試。分析瞭運行過程中過量空氣繫數、煙氣中氧氣含量、 CO含量和排煙溫度的變化，從燃燒和換熱狀況分析鍋爐運行中熱損失的原因。計算得到鍋爐正平衡和反平衡的效率分彆為73．04％和74．90％，平均效率為73．89％，併提齣改善鍋爐能效的整改方案以提高鍋爐熱量利用效率。
