针对目前存在的关于电力驱动和蒸汽驱动高炉鼓风系统能效高低的争议，分别建立了电力驱动和蒸汽驱动高炉鼓风系统的能量利用效率模型和单耗分析模型，从理论上研究了两种驱动系统在能源效率、能源消耗量上的差异。结果表明，电力驱动高炉鼓风系统和蒸汽驱动高炉鼓风系统的能源效率之间存在一定的重合区间，电力驱动高炉鼓风系统的上限能效近似等于蒸汽驱动高炉鼓风系统的下限能效。随着蒸汽温度和压力的提高，高炉鼓风驱动系统蒸汽的消耗量均降低。当驱动的鼓风机确定时，驱动系统的理论最低单耗是特定参数蒸汽的固有特性，与驱动方式和过程无关。鼓风驱动系统的理论最低蒸汽单耗随高炉炉容的增大而减小，随蒸汽温度和压力的升高而降低。
To eliminate the disputes about the energy efficiencies between the electricity-and the steam driven BF blast systems,an energy utilization efficiency model and a unit consumption analysis model were developed in this study to in-vestigate the differences of energy efficiency and energy consumption between electricity-and steam-driven BF blast sys-tems in theory. It is shown that,for energy efficiency,an overlapping interval exists between the electricity-driven BF blast system and the steam-driven BF blast system. And the upper limit of energy efficiency for the electricity-driven BF blast system approximately equals to the lower limit for the steam-driven BF blast system. With the increase of steam temperature and pressure,the steam consumption decreases for both blast systems. When the parameters of blower are constants,the theoretical minimum steam consumption of BF blast system is the inherent property of steam with special parameters,which has no relation with the driven mode and process. The theoretical minimum steam consumption reduc-es while the BF volume,the steam temperature and pressure increase.
