摘要：The invention relates to a method for injecting reducing agents into a shaft furnace in which the reducing agent is transported within a pneumatic delivery stream to the shaft furnace according to the flowing steps; a) dividing the delivery stream into a number of partial streams, b) transferring the individual partial streams through a heating unit, and c) heating the reducing agent within the individual partial streams inside of the heating device. A device for carrying out the inventive method comprises, for example, a delivery line in order to pneumatically deliver the reducing agent to the shaft furnace, and a number of heat exchange pipes which are integrated in the delivery line using a parallel connection, said connection relating to flow techniques, such that the pneumatic delivery stream is divided into a number of partial streams. The inventive device also comprises a heating unit for transmitting heat energy to the individual partial streams.
