ABSTRACT:
The dust removal plant is comprised of a fan with adjustable guide vanes and a ring gap scrubber with adjustable gap width. A first feedback loop controls the scrubber operation through gap width control for maintaining a constant residual dust content of the gas as discharged, a second feedback loop keeps the pressure constant at the scrubber intake by adjusting the guide vanes. Both feedback loops reduce the power consumption of the fan for periods of low dust development. The apparatus is explained with reference to cleaning of smoke gas discharged from a blowing steel converter.
