Tunnel Kiln Solid Fuel Burner System Provides Integrated Solution for Cost Reduction and Efficiency Enhancement in New E

Against the backdrop of continuous capacity expansion and increasingly stringent energy efficiency requirements in the lithium-ion battery anode material industry, the production sector has raised higher demands for the stability and cost control capabilities of thermal equipment. Recently, a significant milestone was achieved in a graphite precursor and lithium-ion battery anode material project — the tunnel kiln solid fuel burner has completed installation and commissioning, officially entering the pre-ignition preparation phase.

This project utilizes needle coke, natural graphite, and asphalt as primary raw materials to produce lithium-ion battery anode materials, while also using natural flake graphite to produce graphite precursors. It stands as a strategically positioned new energy material project in the region. Within the overall process, the carbonization step serves as a core stage, exerting a decisive influence on the thermal system's stability, temperature control precision, and energy consumption levels. The tunnel kiln represents the most critical high-energy-consumption equipment in this process.

The difficulty of balancing high energy consumption with stability. In traditional lithium-ion battery anode material calcination processes, several common issues persist:

1. Suboptimal fuel utilization efficiency, leading to high overall energy consumption.

2. Uneven temperature distribution within the kiln, affecting product consistency.

3. Insufficient operational stability of equipment, increasing maintenance costs and the risk of production stoppages.

These issues directly impact production costs and product quality for manufacturers, acting as significant constraints on further industry-wide efficiency improvement and cost reduction.

To address the challenges mentioned above, this project has introduced a tunnel kiln solid fuel burner solution provided by Brictec. This system is specifically designed based on the characteristics of the carbonization process for lithium-ion battery anode materials, focusing on enhancing combustion efficiency and system stability.

In terms of fuel adaptability, the burner efficiently utilizes solid fuel, achieving complete combustion and minimizing energy waste. Regarding structural design, it effectively improves temperature uniformity within the kiln, ensuring the stability of the calcination process for both graphite precursors and anode materials.

Additionally, the system incorporates enhanced energy-saving control features, contributing to a reduction in energy consumption per unit of product, thereby addressing production costs at the source.

Following continuous construction and systematic commissioning, the tunnel kiln solid fuel burner has now completed all installation and testing work, with all operational indicators meeting the predetermined requirements. The equipment operates smoothly overall, and the control system responds as expected, confirming readiness for ignition.

Upon completion of ignition, the equipment will proceed to the actual production validation phase. This also marks a crucial step in the project's transition from the construction phase towards commissioning and operation.

• Reduce energy consumption in the carbonization process, optimizing the overall production cost structure.

• Enhance temperature control precision within the kiln, improving product consistency and quality stability.

• Increase equipment operational reliability, minimizing unplanned downtime.

• Provide a stable foundation for subsequent capacity ramp-up.

Against the current backdrop of intensifying competition in the new energy materials sector, such technological optimizations focused on core processes will serve as crucial levers for enhancing corporate competitiveness.

The successful completion of installation and testing for the tunnel kiln solid fuel burner underscores the critical value of thermal equipment in lithium-ion battery material manufacturing. With the advancement of the ignition process and subsequent stable operation, the project is poised to further unlock its production capacity, offering a more competitive anode material solution for the lithium-ion battery industry supply chain.
