Effect of Coal Minerals on Chlorine and Alkali Metlas Released during Biomass/Coal Cofiring

摘要

The combustion behavior, gaseous emissions, and alkali metals released during the combustion of several biomass/coal blends were investigated using a direct sampling, molecular beam mass spectrometer (MBMS) system in conjunction with a high-temperature alumina-tube flow reactor. Pittsburgh No. 8 and Eastern Kentucky coals were blended with various biomass samples such As red oak wood chips, Imperial wheat straw, and Danish wheat straw. The coal/biomass blends Were 15/100 biomass on an energy input basis.
