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.

Aim to the problem of gas resource scarcity in future development plan at Bao Steel,outside fuels which were introduced to steel works became necessity,and COREX gas in the highest flight.The various possibilities of introducing COREX gas to fuel gas system were calculated through the principle of fuel gas interchangeability at Bao Steel,and feasibility projects of COREX gas mixing to mixed gas system were solved.

In the light of the national engineering of western natural gas transported to east,the fuel balance condition of Bao Steel Co.was presented.The gas combustion theory was used to analyze the plan to popularize and apply the natural gas in Baoshan Iron Steel Co.Based on this the variety in environmental protection and structure of energy sources consumption was researched.

Baosteel’s BFG and LDG systems are introduced in this paper.Dust composition in the gas is measured,and a relatively complete and detailed analysis of 28 kinds of dust in the gas has been made for the first time.It has provided scientific basis for extensive use of gas.
