<p>Apparatus for continuously conveying and pre-heating a metal charge (13) inside a container (12) of a melting plant (11), comprising at least a conveyor channel (21), having walls (38, 39) to convey the metal charge (13), and at least a hood (17) defining a conveyor tunnel and/or an expansion chamber (18). The hood (17) is disposed above the conveyor channel (21) for the transit of at least part of the fumes exiting from the container (12), and the conveyor channel (21) cooperates with apertures (30) to discharge the fumes. The apertures (30) cooperate with at least a fume diverting channel (44) defining at least a first expansion compartment (27), located substantially vertical or sub-vertical, connected both to the apertures (30) and also to at least a channel (25, 26) to take in the fumes.</p> |
