DP&L SYSTEM DESIGN CHALLENGES

摘要

Black & Veatch faced unique design and construction challenges at both Dayton Power & Light (DP&L) Ohio sites when the CT-121 system, The first was constructing fiberglass vessels and internals in the field and attaching ducts of high nickel metal alloys (including internal and external alloy and fiberglass piping) to the fiberglass vessels. The heart of the process at all five DP&L units is a jet bubbling reactor (JBR) scrubber vessel. The vessel stands approximately 75 feet tall and measures approximately 87 feet in diameter. Moving the process slurries and water throughout the system entails 30,000 feet of pipe at Killen and 90,000 feet of pipe at the four Stuart units. Black & Veatch's design team worked along DP&L and with Chiyoda's experts to complete the installation.
