河南特大型高炉“吃”上生物质炭

Core Viewpoint - The collaboration between Henan Steel Group and Beijing University of Science and Technology has successfully conducted the first industrial trial of a 4000m³ blast furnace using biomass carbon injection, marking a significant step towards low-carbon fuel alternatives in steel production [1] Group 1: Industrial Trial Details - The trial was implemented at the Anyang base, achieving a coal ratio of 170 kg/tHM and a stable daily production exceeding 10,500 tons [1] - The biomass carbon injection process was found to be safe and controllable during the trial [1] Group 2: Characteristics of Biomass Carbon - Biomass carbon is identified as a renewable low-carbon solid fuel with high reactivity, excellent combustion performance, and low carbon emission intensity [1] - It can partially replace injected coal while ensuring the stability of the blast furnace operation and the quality of molten iron, thus reducing fossil energy consumption [1] Group 3: Systematic Verification and Data Support - The trial focused on the feasibility of biomass carbon in the blast furnace injection system, operational stability, and carbon reduction potential [1] - A comprehensive process chain was established, covering aspects from raw material management to continuous injection in the blast furnace [1] - Key parameters such as the grinding and injection system, combustion state in the tuyeres, and overall furnace stability were monitored to assess the impact of biomass carbon injection on furnace operation and fuel structure optimization [1]
