Dust removal from de-ashing system waste air - by introduction into flue gas ahead of electrostatic filter

摘要

In a process and appts. for dust removal from an ash dust-waste air mixt. from the de-ashing system of a coal-fried power station, the novelty is that the mixt. is introduced transversely as subdivided streams into the flue gas stream upstream of the pptn. and unflow devices of an electrostatic filter. ADVANTAGE - The process is integrated in the flue gas treatment process, has reduced prodn., operating and repair costs and gives considerable redn., in residual dust content.
