LOW-CARBON AND ENERGY SAVING TECHNOLOGY APPLIED IN ANSTEEL BAYUQUAN BRANCH COMPANY

摘要

The technology of energy saving and low-carbon operation in Ansteel Bayuquan Branch Company are introduced in this paper. By adopting Didier external combustion hot stove and preposed combustion stove for preheating, top gas pressure recovery turbine(TRT), combined cycle power plant(CCPP), frequency conversion fan in coal powder carrying system, waste heat utilization in slag granulating process and etc. The energy consumption in whole BF system has been reduced to some extent. At the same time, a series of measures have been taken to lower the fuel rate and approach the low-carbon BF operation, which are using beneficiated burden materials, optimizing charging model and adjusting blowing rule to improve the gas utilization ratio, keeping adapted smelting intensity and cooling intensity.
