Summary

Machine-generated summary

Hamburger Energiewerke GmbH, the municipal energy supplier of Hamburg, Germany, is procuring pressure part modifications for two coal-fired steam generators at the Tiefstack combined heat and power plant as part of the TiTra programme, which aims to phase out coal-based district heating by 2030 and switch to natural gas with low-sulphur heating oil as backup fuel. Lot 6 covers replacing non-compliant pressure part components in the superheater areas, ensuring permissible tube wall temperatures and stresses, and integrating new components including static calculations, welding, testing and inspection.

Description

Die Hamburger Energiewerke GmbH (HEnW) sind ein 100 % städtischer Energieversorger. Zur Erreichung der Klimaziele der Freien und Hansestadt Hamburg soll der Anteil der kohlebasierten Fernwärme bis 2030 von aktuell ca. 64 % auf null reduziert werden. Hierzu wurde das Programm "Tiefstack Transformation (TiTra)" initiiert. Am Standort Heizkraftwerk (HKW) Tiefstack erzeugen derzeit zwei steinkohlebefeuerte Dampferzeuger im KWK-Betrieb Strom und Fernwärme. Zur Dekarbonisierung dieses Standortes ist die Substitution des Brennstoffs Steinkohle durch Erdgas (H-Gas) vorgesehen. Ergänzend sollen die Dampferzeuger übergangsweise mit Heizöl EL (HEL schwefelarm nach DIN 51603-1) betrieben werden können. Ziel des Loses 6 ist die druckteilseitige Anpassung beider Dampferzeuger an den zukünftigen Erdgasbetrieb durch: - Ersatz unzulässiger Druckteilkomponenten im Überhitzerbereich (Ü2, Ü3, Ü4) durch neue Bauteile mit geeigneten Werkstoffen und Auslegung gemäß TRD, - Sicherstellung der zulässigen Rohrwandtemperaturen und Spannungen für alle relevanten Lastfälle Sicherstellung der zulässigen Rohrwandtemperaturen und Spannungen für alle relevanten Lastfälle (100 %, 70 %, 40 % Last, Ein-/Zwei-Kessel-Betrieb) - Integration der neuen Komponenten in den bestehenden Kessel inklusive statischer Nachweise, Schweißtechnik, Prüfungen und IBS
