Mechanism of surface enrichment and adhesion of coal combustion particulates
Following is an updated list of accomplishments: Design of an experimental set up and development of experimental techniques for study of the adsorption and desorption of alkali on coal ash and potential additive particles. Development of techniques for quantitative and qualitative characterization of alkali distribution in small additive particles using Scanning Auger Spectroscopy. Completion of a set of adsorption experiments for measuring the rate, capacity and adsorption characteristics of alkali adsorption on bauxite, silica, lime and kaolin. Design and set up of a micro-fluidized bed for study of the agglomeration kinetics and characteristics of ash and additive particles. Completion of the first set of experiments on dependence of agglomeration characteristics on the alkali content of typical ash and potential additive particle.
