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]

Group 1 - Nian Da Environment successfully sold 7 tons of carbon credits on the international carbon credit certification platform Puro, becoming the first domestic project to achieve this [1] - The company has developed a multi-production gasification furnace in collaboration with experts from Nanjing University of Science and Technology and Nanjing Forestry University, which can convert various crop straws into biomass charcoal [1][2] - The application of biomass charcoal has shown to increase soil organic matter content by over 20% and reduce chemical fertilizer usage by 15%-20%, effectively improving crop yield and quality [1] Group 2 - The project utilizes agricultural waste, converting it into biomass charcoal through high-temperature pyrolysis, which stabilizes carbon for over a century [2] - Each ton of biomass charcoal applied is equivalent to removing 1.5 tons of carbon dioxide, contributing to the carbon removal market that is rapidly growing globally [2] - The company can process approximately 8,000 tons of straw annually from over 10,000 acres of farmland, producing around 2,000 tons of biomass charcoal [2] Group 3 - Biomass charcoal reduces chemical fertilizer usage and lowers agricultural non-point source pollution, while also improving environmental quality, indicating a promising "blue ocean" industry [3] - Nanjing has been enhancing services for enterprises and promoting the healthy development of the biomass charcoal industry, achieving a straw comprehensive utilization rate of over 96% [3]
