Das Projekt "PRE-ENVPROT 3C, Pulse Energization System to Enhance Electrostatic Precipitator Performance" wird/wurde gefördert durch: Kommission der Europäischen Gemeinschaften Brüssel. Es wird/wurde ausgeführt durch: Walther & Cie AG.Objective: To contribute to solve the problem of the separation of highly-resistant dust in electrostatic precipitator application. General Information: High voltage pulses are used in order to have a high level of performance for the electrostatic precipitators; these pulses can be varied in level and duration. Large electrostatic precipitators establish the effectiveness of pulse generators and their reactions to various dust granulometries. The experimental device consist of a three- phase high tension generator, a pulsator, a high capacity condenser on the pulsator side and a high capacity choke on the basic voltage side. Comparative measurements are made in a four-chamber electrostatic precipitator charged with an electrical field which is equipped with a pulse generator.
