59.溶射バーナを用いた模擬石炭灰による付着実験

抄録

Recently, high temperature coal utilization technologies have been focused. However, those technologies have some problems such as slagging and fouling due to molten coal ash. Therefore, it is necessary to study characterization of ash deposition and its mechanisms. This work studies fundamental characteristics on ash deposition, using a thermal spraying burner. Several kinds of inorganic particle are tested as a simulated coal ash. In the experiments, the deposition mass was weighed, and cross-section of the deposition layers was analyzed by a scanning electron microscope.
