Application of an Electrostatic Precipitator for Instrumental Sampling of Sulfuric Acid

摘要

A means of separating gaseous sulfuric acid from flue gas particles has been evaluated. Previous attempts to achieve separation by filtration resulted in retention of the acid by the particulate buildup on the filter surface. A laboratory study of a prototype electrostatic precipitator, followed by actual flue gas sampling, indicated that the precipitator may eliminate the need for a filter without affecting the measurement results. The study also showed that the precipitator could be used preceding a prototype acid monitor for the continual monitoring of H2SO4 in combustion gases.
