Abstract (en)

The fluid medium to be heated passes through an initial heating system (2,3) and at least one following heating system (5,6). Each heating system has heat exchangers (2,5) in contact with the medium flow, with higher temp. levels at the second system (5,6) than in the first (2,3). The direct medium flow into the first heating system (2,3) is reduced, to accelerate the increase in temp. and, in extreme cases, is stopped, and the medium within the first system (2,3) is recirculated. The medium can be fed directly to the second heating system (5,6), with medium recirculation in the first system (2,3) or a combined recirculation in both systems (2,3;5,6).

Abstract (de)

Die Erfindung betrifft ein Verfahren zum Erwärmen eines flüssigen Mediums mittels einem ersten (2,3,4,7,12,13) und mindestens einem diesem nachfolgenden zweiten thermischen System (5,6,6A,15,16), welche thermischen Systeme jeweils mindestens einen vom Medium durchströmten Wärmetauscher (2,5) aufweisen und welches zweite thermische System (5,6,6A, 15,16) auf einem höheren Temperaturniveau als das erste (2,3,4,7,12,13) betrieben wird. Das Verfahren ist dadurch gekennzeichnet, dass zur beschleunigten Anhebung der Temperatur des Mediums im ersten thermischen System (2,3,4,7,12,13) die direkte Zufuhr des Mediums zu demselben vermindert und im Extremfall unterbunden wird, und dass das erste thermische System (2,3,4,7,12,13) durchströmende Medium kreislaufgeführt wird. Die Erfindung betrifft auch eine Anlage zur Durchführung des Verfahrens. <IMAGE>
