摘要

Experiments were carried out on a tubular furnace. The results showed that the released amount of K and Cl increased with the wheat straw share of the blends, meanwhile the released amount of Cl was far more than that of K. Al and Si from coal can capture K to form KAlSi_xO_y, which would promote the release of HCl. The activity of Al and Si increased with the temperature rising. During combustion, Ca and Mg can react with Al and Si, resulting in an increased release of K and a decreased release of HCl indirectly.
