Kaolin additivation in pulverized wood firing systems – potassium capture, emissions and ash behavior

Key Points

• Lower emissions result from improved potassium capture using kaolin, enhancing environmental safety.
• Potassium capture increased significantly when kaolin was added, reducing overall pollutant output.
• Assessment using detailed emissions measurements and ash composition analysis shows better ash management.
• Findings support the use of kaolin as a promising additive for cleaner combustion technology.
