Energy Saving Bottleneck Analysis in Iron and Steel Plant Based on Decomposition Model of Energy Consumption Index

摘要：

This paper applied the decomposition model of energy consumption index on the four-grade structure, from main-process stream to equipment, of a Chinese iron and steel plant (here after refers to plant A). Based on the data of energy consumption of plant A of resent years, the change of energy consumption per ton steel was decomposed into production factor and energy intensity factor, to analyze the two factors influence on the total index. The model analysis showed that, the production structure of 1750m3 blast furnaces was the bottleneck of energy saving. Thus decreasing steel-iron ratio will be most effective to reduce the energy consumption of plant A. The further analysis shows that the energy consumption per ton steel would be decreased by 3Skgce/t if the steeliron ratio reduced from 0.98 to 0.90.
