Efforts and Results of Production Increasing and Consumption Reduction in Xianggang No.3 BF
The efforts and results of increasing production output and reducing energy consumption in Xianggang No.3 BF are introduced.For this furnace,central coke charging is adopted,but both the coke rate and fuel rate are high,and the daily output fails to reach the required one due to shortage of high-quality self-produced coke and usage of a large amount of poor quality coke outsourced.After improving coke quality,optimizing the operating system,and implementing delicacy operation management,the gas flow distribution of the furnace becomes better,the furnace operating profile is more stable,the main techno-economic indicators improve gradually,and a significant achievement is seen in the efforts of production output in-creasing and consumption reduction.From January to February 2023,the daily production output of the furnace rises to over 5600t/d,the productivity hits 3.11t/(m3·d),the coke rate drops to 355kg/t,and the fuel rate falls to less than 515 kg/t.
