| description | Physicochemical properties of ash particles and their effects on the collection characteristics of electrostatic precipitator in the pulverized coal combustion system were investigated, focusing on enrichment processes of sulfur on the particle surface. An experimental system composed of one-dimensional laminar flow furnace, cyclone, bag-filter and electrostatic precipitator was used to derive the mutual relations among coal properties, combustion conditions and characteristics of ash particles collected in each device. The following conclusions were obtained. 1) Chemical properties on the particle surface are affected not only by the shape and surface structure of particles but also by particle size, temperature history and coal properties. 2) Soot particulates attached to the small ash particles enhances the enrichment of sulfur on them, and this effect depends on coal properties and combustion conditions. 3) Collection characteristics of ash particles in the electrostatic precipitator largely depend on the enrichment behavior of sulfur in it for the case of high sulfur coal.† This report was originally printed in KAGAKU KOGAKU RONBUNSHU, 10(6), 751-757 (1984) in Japanese, before being translated into English by KONA Editorial Committee with the permission of the editorial committee of the Soc.
