Abstract
A device for discharging dust from a dry dust collector of a blast furnace includes a dust discharge vent located downstream of a dust discharge opening of the dry dust collector. A fully enclosed dust conveying system is located downstream of the dust discharge valve and provides mechanized transport of the dust discharged through the discharge valve. A control system is utilized to control the opening of the dust discharge valve in relation to the residual conveying capacity of the dust conveying system.
