Evaluation of the cold pipe precharger

A model is developed in order to evaluate the cold pipe precharger, which was developed to reduce the resistivity of the dust layer collected on the cold pipe surface and also to achieve very high levels of charge on dust particles in a very short distance along the direction of gas flow. The approach requires detailed descriptions of electrical characteristics, electrohydrodynamics, and charging theory. The computations used to predict the particle charge values of the cold pipe precharger are given. The computed size-dependent particle charge showed good agreement with the experimental data, and the developed model is capable of providing good evaluations of the cold pipe precharger.<
