Measurement and Prediction of the Resistivity of Ash/Sorbent Mixtures Produced bySulfur Oxide Control Processes

摘要

The report describes the development of (1) a modified procedure for obtainingconsistent and reproducible laboratory resistivity values for mixtures of coal fly ash and partially spent sorbent, and (2) an approach for predicting resistivity based on the chemical composition of the sample and the resistivities of the key compounds in the sample that are derived from the sorbent. Furnace and cold-side sorbent injection technologies for reducing the emission of sulfur
