Source profile of TSP and PM_（10） from coal-fired boilers
Abstract：A dilution sampling system was used to collect fly ashes in stack gas from coal-fired boilers while a re-suspended sampling chamber was adopted to collect ashes captured by emission control devices.Chemical profiles for TSP and PM10 were established by the two methods.The main chemical components for particulate matter from coal-fired boilers are TC,OC,Si,Al,Ca,Na,Mg,Fe and SO2-4.Si and TC are the most abundant species in TSP and PM10 profiles.As for trace elements,Cr,Zn,As,Pb and Cu are enriched in PM10 when compared to raw coal.There exist diversities for profiles obtained from boilers with wet and dry dust removal devices.Coefficient of divergence analysis indicate that profiles for dilution stack sampling and re-suspended sampling methods are different.
