Abstract: Electricity is an important energy in the production of iron & steel factory, which plays a decisive role in the whole process. This paper presents four kinds of models of steam generation technologies in integrated iron and steel industries. Energy inputs, electricity outputs, recovered waste heat efficiencies of boilers, steam turbines, gas turbines and coal-fired of the models were analyzed by using input-output method. Electric conversion, waste heat recovery and overall conversion efficiencies were compared with the actual data of three typical iron and steel enterprises. The models were discussed. And it is found that these established models have important guiding significance for power production in iron and steel enterprise.

Key words: input-output method, electric conversion efficiency, steam generation, waste heat recovery efficiency, overall conversion efficiency
