Abstract: A system is provided for improving dust collection efficiency at a sinter band device. The system includes a sinter band with material handling stations and auxiliary equipment operative to sinter a metal or metal ore, a primary electrostatic precipitator operative to remove primary dust from a primary gas stream that has passed through a bed of sintering material on the sinter band, and a secondary dust collection device operative to remove secondary dust from a secondary gas stream emanating from one or more suction points at the material handling stations and the sinter band. The secondary dust has a lower electrical resistivity than the primary dust. A dust transportation line is provided operative to transport secondary dust to the primary gas stream downstream of the sinter band, and injecting it at a position upstream of the primary electrostatic precipitator and/or directly into the precipitator itself.

Abstract: An electrostatic precipitator having a collecting electrode plate assembly, including at least two electrode plates disposed substantially in a parallel to each other in the vertical plane within the electrostatic precipitator, forming a space between the collecting electrode plates, and a discharge electrode assembly interposed in said spaces, wherein the electrode assembly passing at least a supporting structure of the collecting electrode plate assembly. The supporting structure is provided with an electrical screening device at least in the area of the supporting structure facing said electrode assembly.
