Installation and process for continuously charging a reactor with solid material and heating said material with the gases emitted from said reactor

摘要

The installation permits continuous charging of solid material (2) such as steel scrap into a reaction vessel (1) such as a converter for steel manufacture, the steel scrap being heated by heat exchange with the gases (G) emitted from the converter. To this end, the scrap (2) is fed into a compartment (3) provided with a discharge opening placed above the mouth (6) of the converter (1) from which the hot gases (G) are emitted, the scrap (2) is displaced towards the discharge opening (5) and the hot gases (G) are aspirated so as to circulate through the scrap (2) in countercurrent flow with respect to the direction of displacement (D) of the scrap.
