摘　　要： 通过测试燃料量、燃料成分、锅炉供风量、供水量、烟气成分、排烟温度等参数,应用注汽锅炉能量分析方法,计算出锅炉的正平衡效率和反平衡效率,误差最大为2.54%。通过对注汽锅炉进行能耗分析,找到影响注汽锅炉效率的主要因素,对发现耗能节点及挖掘节能潜力有重要作用,最终得出产生相同蒸汽量时过热蒸汽锅炉所需的燃料量。锅炉运行过程中,过剩空气系数偏大是影响注汽锅炉效率的主要因素。除了回收烟气中的氮气的热量以及水蒸汽的显热资源外,回收水蒸汽的潜热可使锅炉效率大幅度提高。消耗相同燃料产出的湿饱和蒸汽量比产出的过热蒸汽量更多;产生相同蒸汽量时,产出过热蒸汽所需消耗的燃料量较大。 This paper, based on testing fuel quantity and components, air quantity, smoke components and exhaust temperature, uses energy analysis of steam generator to calculate the positive and reverse balance efficiencies at a maximum error 2. 54%. Energy consumption analysis is conducted to find the major factors of steam generator efficiency, which plays a vital role in finding energy consuming processes and exploring saving energy. Fuel quantity in the overheated steam generator is calculated as the same steam quantity is generated. When generator is running, excess of air is the key factor impacting generator＇s efficiency, which may be largely increased by recovering the heat of nitrogen in the exhaust and sensible heat in the steam along with recovering the latent heat of steam. The same fuel will produce more wet saturated steam than overheated steam, and more fuel is consumed to produce overheated steam with the same steam quantity.
