The collection efficiency of ESP model - Comparison of experimental results and calculations using Deutsch model

In spite of considerable progress in the field of numerical techniques, the models based on simplified equations are still in use in practice. In particular, the Deutsch model is often used for the description of transport and separation of dust particles in EHD field inside electrostatic precipitator (ESP). The aim of the research presented in this paper was to compare the value of collection efficiency determined experimentally and calculated using the Deutsch model. Besides, an attempt to model the phenomena of transport of dust particles in laboratory ESP using the Deutsch model was undertaken. The rigid discharge electrode in the form of spliced pipe was used in these experiments. Overall and fractional collection efficiencies were determined for two kinds of fly ashes of different particle size distributions. The overall collection efficiency was determined experimentally and compared with the results obtained from Deutsch formula. The results have shown that the collection efficiency determined using two methods: experimental and calculated by the Deutsch model were consistent.
