Method and device for producing anodes

摘要

An air feeding device for producing anodes in an annular kiln includes at least one kiln unit having a heating zone, a firing zone, and a cooling zone, each having a plurality of kiln chambers which are interconnected by heating channels, are formed as heat exchangers and are used to receive anodes. Primary air is introduced into the cooling zone by a primary air feeding device for the passage of air through the kiln unit and, once it has passed through the firing zone, being discharged from the heating zone as flue gas by means of an exhaust device. Secondary air is fed into the heating zone upstream of the exhaust device by a secondary air feeding device.

1. A method for producing anodes in an annular kiln, said kiln including at least one kiln unit having a heating zone, a firing zone, a cooling zone, and a plurality of kiln chambers interconnected by heating channels forming heat exchangers used to receive anodes, said method comprising:
introducing primary air into the cooling zone using a primary air feeding device for the passage of air through the kiln unit; discharging the primary air from the heating zone as flue gas using an exhaust device once the primary air passed through the firing zone; feeding secondary air into the heating zone upstream of the exhaust device with regard to a direction of the primary air flow, using a secondary air feeding device; and positioning said secondary air feeding device as a function of at least one process parameter.
