Effect of SO2 circulation on pellet quality in grate-kiln process

Key Points

• Improved pellet quality results from enhanced SO2 circulation during processing, which optimizes thermal conditions.
• Increased thermal efficiency, leading to a production rate of over 15% higher pellets compared to conventional methods.
• This observational analysis assesses various SO2 circulation levels in the grate-kiln production process across multiple operational conditions.
• Understanding the influence of SO2 circulation may enable better resource management in industrial pellet production.
