A critical review on potassium release, transformation, and fixation during biomass combustion

Key Points

• Potassium release significantly affects the outcomes of biomass combustion, altering ash quality and environmental emissions.
• Up to 40% of potassium may be released during combustion, influencing both energy recovery and pollution levels in the atmosphere.
• Analysis of data from multiple studies reveals complex interactions in the potassium transformation process during thermochemical reactions.
• Understanding potassium dynamics in biomass combustion is crucial for optimizing energy production and reducing environmental harm.
