• 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 mode. 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). In addition to the pure fuel change, efficiency measures are being implemented. Lot 4 contributes to this by extracting waste heat from the flue gas before the induced draft and feeding it into the heating water network. Tiefstack Transformation (TiTra) - Award Unit 4 (Lot 4) Waste heat utilization The project scope of award unit 4 (lot 4) is: Planning, delivery, construction and commissioning of a system-safe waste heat utilization system, consisting of: - two identical flue gas heat exchangers per line in the former REA, - a hydraulically connected heating water circuit including a pipe bridge into the existing system, - all the necessary auxiliary units and the associated EMSR? and steel construction technology in order to feed a defined portion of the flue gas heat into the heating water network and thus increase the overall efficiency...
