Abstract
Five coals containing 1% to 5% sulfur and <0.3% to 0.5% chlorine were co-fired with simulated refuse derived fuels (RDF) in air at the heating rates of 10°C/min and 100°C/min. A TG/FTIR/MS analytical system was used to determine and characterize the evolved gaseous products during combustion. More than 15 inorganic and organic compounds were determined in the evolved gases. The discovery of molecular chlorine as a product is significant for us to understand the reaction pathways for the formation of chlorinated organic compounds. The combustion profiles of the fuels and the kinetics of the formation of important gaseous products were also investigated. It was determined that chlorine and hydrocarbon species are released in the same temperature range and in higher concentrations at the fast heating rate than in the slow one. This result indicates that there are more opportunities to form chlorinated organic compounds during combustion at the faster heating rate that may occur in an AFBC system. It was demonstrated that the TG/FTIR/MS system is a convenient means of evaluating the forms of sulfur present in coal by analysis of the sulfur dioxide released during combustion.
