<p>1. A device for utilizing the heat in the waste gas of a plurality of discontinuously operating processing areas (1, 2), having a heat exchanger (15) disposed in the path of the waste gas and a control means for the final temperature of the heat exchanger medium, characterized in that all processing areas (1, 2) are connected to a common waste gas branch line (9, 10), and there is associated with the waste gas branch line (9, 10) a waste gas volume control circuit which is provided with a nominal value input for the desired final temperature of the heat exchanger medium and a temperature-measuring sensor (18) at the output of the secondary circuit (16) of the heat exchanger (15) and a controllable blocking means (14) in the waste gas branch line (9, 10).</p> |
