Boron contained in coal are partly released to the flue gas during combustion. Boron are captured in flue gas cleaning systems and the emissions of these elements are generally low. However, it is important to understand the behavior of boron to improve the reliability of the gas cleaning systems. Though a lot of researches examined the behavior of boron, the behavior of these elements in coal combustion has not been clarified in detail yet. In this research, the release behavior of boron from coal was investigated using a drop tube furnace (DTF). As a result, it is thought that a part of the boron would be absorbed in molten slag during combustion.
