ABSTRACT

Following a former project where a tangential entry electrocyclone was built and tested, the present project deals with the demonstration of economic and technical validity of an electromulticyclone for coal burner exhaust gas cleaning. The first phase of the project is being completed. A single cell of electrocyclone, adapted from a commercial multicyclone cell, was built and tested in laboratory and industrial conditions. Electric insulation was improved, electrode geometry optimized, and a rapping defouling device was installed and tested. Results show that electrostatic collection efficiencies of 50% to 80% could be attained with modified cyclones where residence time would be increased.
