【 摘 要 】

References(14)Cited-By(1)Characterization and measurement of condensable suspended particulate matter emitted from stationary sources, such as coal-fired power plants and waste incinerators, are very difficult since dust concentration in exhaust gas is usually measured at the downstream of dust collectors kept at relatively high temperatures compared with atmospheric air. In the cooling process of flue gas, compounds having solidification points between dust collector temperature and atmospheric temperature have the possibility to become condensable suspended particulate matters. In this work exit gas after bag filtering emitted from a laboratory scale fluidized bed combustor burning refuse-derived fuel (RDF) was sampled by two kinds of cooling methods and elemental analysis was performed. In the experimental results the elemental permeability of a bag filter was high for Pb, Cd, and Zn. To discuss the contribution of fuel composing elements as the origin of measured condensable suspended particulate matters, thermodynamic calculation was performed and the possibility of Cd emission was supported.
