ELECTRODE POUR DISPOSITIF DE REVETEMENT COMPORTANT UN LIT FLUIDISABLE

摘要

An electrode for a fluidised-bed coating apparatus consists of a multiplicity of electrically conductive tubes (12) seated in a tube carrier (10). The tubes project from the carrier and have free ends (18) at which a concentration of the electrical field intensity occurs when the tubes are connected to an electrical potential via terminals (14, 16), and the tubes produce a channelling of the turbulent gas through the concentration points of the electrical field intensity. <IMAGE>
