Boron and selenium exist as gaseous and particle phases in coal flue gas. They are partitioned into four components, bottom ash, fly ash, FGD waste water, and emission gas discharged into the atmosphere. The ratio of the components varies depending on coal properties and combustion conditions. Therefore, it is necessary to measure these components accurately to understand boron and selenium's behaviors during coal combustion. In this study, we developed the optimum sampling methods for gaseous boron and selenium using a new absorbent and a solvent for rinsing sampling tubes. Also, we collected data at a turbulent furnace test facility to discuss material balances and the behaviors of boron and selenium.
