Abstract

Die Vorrichtung zur Versorgung eines Dampfverbrauchers (100) in einer Maschine zur Herstellung oder Verarbeitung eine Faserstoffbahn umfasst einen dampfbeheizten Zylinder (1), eine Dampfzuführung (2), welche Dampf auf einem zweiten Druckniveau für den dampfbeheizten Zylinder (1) bereitstellt, und welche mit einem Frischdampfnetz (10) verbindbar ist, eine Kondensatrückführleitung (3) zur Führung von aus dem dampfbeheizten Zylinder (1) entnommenem Kondensat, eine Dampferzeugungsvorrichtung zur Verdampfung des aus dem dampfbeheizten Zylinder (1) entnommenen Kondensats, sowie eine Rückspeiseleitung (6) zur Versorgung des Dampfverbrauchers (100) mit dem erzeugten Dampf. Die Dampfzuführung (2) ist vom Frischdampfnetz (10) entkoppelt. Zusätzlich umfasst die Vorrichtung einen Thermokompressor (7) zur Versorgung des dampfbeheizten Zylinders (1), welcher mit einem Dampfnetz verbindbar oder verbunden ist, das Treibdampf auf einem Druckniveau zur Verfügung stellt, das höher ist als das zweite Druckniveau. Die Erfindung umfasst auch ein Verfahren zur Versorgung eines Dampfverbrauchers (100) in einer Maschine zur Herstellung oder Verarbeitung eine Faserstoffbahn.The device for supplying a steam consumer (100) in a machine for producing or processing a fibrous web comprises a steam-heated cylinder (1), a steam feed (2) which provides steam at a second pressure level for the steam-heated cylinder (1), and which with a live steam network (10) can be connected, a condensate return line (3) for guiding condensate taken from the steam-heated cylinder (1), a steam generating device for evaporating the condensate taken out of the steam-heated cylinder (1), and a return line (6) for supplying the Steam consumer (100) with the steam generated. The steam supply (2) is decoupled from the live steam network (10). In addition, the device comprises a thermocompressor (7) for supplying the steam-heated cylinder (1), which can or is connected to a steam network which provides motive steam at a pressure level which is higher than the second pressure level. The invention also includes a method for supplying a steam consumer (100) in a machine for producing or processing a fibrous web.
