Abstract

Quantify the potassium in biomass combustion residues is an alternative way to study the release mechanisms of potassium which is essential to mitigate the ash-related problems while using biomass fuels. In this work, different combustion parameters were used to study the retention of potassium via high-temperature furnace balance system and then Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES). Through the investigation, final temperature influences the retention of potassium the most, there is 80% of potassium left when temperature is 200℃, while this number sharply dropped to 42% when temperature reaches 1000℃. There is a little different of the retained potassium between the heating rate of 500℃/h and 1000℃/h at selected temperatures, while the high heating rate (1500℃/h) results in the 20% less of retained potassium compared to that of the heating rate of 1000℃/h. The influence of isothermal time is insignificant when temperature
