Baosteel Branch's Gas Utilization Reaches World Leading Level

Owing to the sustained innovation practices for many years, now Baosteel Branch's blast furnace gas emission ratio is less than 1.5%, 99 Nm3 BOF gas is recovered per ton of steel, zero emission is maintained for coke oven gas and the utilization of by-product gas steadily steps into the leading position in the world.

Since Phase III project was put into operation, Baosteel Branch's production scale has kept expanding, so the bottleneck in fuel gas system becomes more and more serious and thus constrains the progress of energy saving and emission reducing technologies. Since 1996, Baosteel Branch has been unremittingly exploring the comprehensive utilization technologies for by-product gas with the target to catch up with and surpass the international leading level.

After the practices for many years, Baosteel Branch has made remarkable achievements in terms of gas recovery and utilization, system monitoring and adjustment, economic operation and decision-making, providing important support to improve the utilization of by-product gas and emission reduction technologies.

Through technology innovation, Baosteel Branch substantially improves the recovery capacity for BOF gas, effectively alleviates the conflict between gas recovery and utilization imbalance and solve the quality problem of coke oven gas for cold rolling which has been perplexing for many years; a generating set that combusts pure blast furnace gas has been completed, which greatly improves the utilization level of blast furnace gas; the key equipment in fuel gas system can be manufactured locally, thus lowering the maintenance cost and improving the safety and lifetime of fuel gas facilities; corporate ERP level energy database has been developed successively to realize the automation and informationization of fuel gas system.
