Particulate Collection Efficiency Measurements on an Electrostatic Precipitator Installed on a Paper Mill Recovery Boiler,

摘要

The report gives results of fractional and overall collection efficiency measurements of an electrostatic precipitator collecting 'salt cake'from a Kraft recovery boiler. Mass median diameter of the particulate entering the collector was approximately 1.0micrometers;minimum average collection efficiency in the 0.1-2.0micrometer diameter range was 99.92%. Size distributions at the precipitator inlet and outlet were measured with cascade impactors and an electrical aerosol analyzer. Overall mass efficiency measurements,based on a mass train with an in-stack filter,ranged from 99.92to 99.96%. Fair agreement was obtained between the total mass loadings obtained with the mass trains and the impactors.
