Abstract

Characteristics of the carbon components and the particle size distribution of the particulate matter emitted from the biomass boiler were studied by collecting PM₁₀ and PM_2.5.The organic carbon (OC) and elemental carbon (EC) in the sample were determined by the thermal/optical reflectance (TOR), the quantity of char-EC and soot-EC were obtained. The results showed that different removal ways of dust had significant effects on OC and EC quantity in particulate matter discharged from biomass boiler. The value of OC/EC and char-EC/soot-EC as indicators of identification of source were 1.4±0.4 and 35.7±16.5 respectively in PM₁₀, 2.2±1.3 and 15.5±10.3 in PM_2.5 respectively in the bag dust removal samples. The 10 value of OC/EC and char-EC/soot-EC in cyclone dust samples of were 6.1±1.9 and 5.2±2.5, and the PM_2.5 were 6.5±2.0 and 2.5±2.3 respectively. For carbon fractions:OC1~OC4, EC1~EC3 and OPC analysis, the percentage of EC1in TC was the highest in the bag dust removal samples. The cyclone dust samples of relative contents of OC1~OC3 in TC were higher than others. This study also showed that OC2, OC3 and EC2 were mainly concentrated in PM_2.5, OC4, ECl and EC3 mainly in PM₁₀.
