The paper discusses detailed numerical calculations of particle charge and extinction coefficient performed using current models. The results suggest that information about rapping reentrainment, back corona, and, possibly, sulfuric acid condensation can be gained from simultaneous outlet measurements of opacity and space charge. Some experimental observations based on semicontinuous measurements have confirmed these results in a general way and point to the use of the method as a precipitator diagnostic tool.
