State of the Art: 1971. Instrumentation for Measurement of Particulate Emissions from Combustion Sources. Volume III. Particle Size.

摘要

The report discusses candiate techniques for automatic or semi-automatic measurement of particle size distribution in combustion source effluents. Automatic or semi-automatic particle size measuring instruments do not yet exist for this application. This report considers the application to effluent streams of particle size measuring instruments used in other fields. The discussions emphasize the particulate concentration parameter (mass,number,surface area,etc.) which each technique senses as well as the method of classifying particles into size ranges (aerodynamically,electrostatically,optically,etc). Included are description of the basic operation of each technique,discussions of limitations of each technique,suggestions of possible major problems in applying each technique to effluent streams and an overall evaluation of each technique relative to others.
