• Description:
• Hamburger Energiewerke GmbH (HEnW) is a 100% municipal energy supplier. In order to achieve the climate goals of the Free and Hanseatic City of Hamburg, the proportion of coal-based district heating is to be reduced from currently around 64% to zero by 2030. On this The “Tiefstack Transformation (TiTra)” program was initiated. At the Tiefstack combined heat and power plant (HKW) site, two hard coal-fired steam generators are currently generating electricity and district heating in cogeneration operation. To decarbonize this location is substitution the fuel hard coal is replaced by natural gas (H-gas). In addition, the steam generators should be able to be operated temporarily with heating oil EL (HEL low sulfur according to DIN 51603-1). Project: Deep stack transformation (TiTra) - operation with gas (BmG) - Award unit (lot) 6 boiler pressure part modification The aim of Lot 6 is to adapt the pressure part of both steam generators to future natural gas operation by: - Replacing impermissible pressure part components in the superheater area (Ü2, Ü3, Ü4) with new ones Components with suitable materials and design in accordance with TRD, - Ensuring the permissible pipe wall temperatures and stresses for all relevant load cases Ensuring the permissible pipe wall temperatures and stresses for all relevant load cases (100 %, 70%, 40% load, one/two boiler operation) - Integration of the new components into the existing boiler including static verification, welding technology, tests and IBS Doc Title: Project: Deep stack transformation...
