Seed regeneration system integration issues and economics
- Westinghouse Science & Technology Center, Pittsburgh, PA (United States)
Westinghouse Electric Corporation, through Contract No. DE-AC22-87PC79668 funded by U.S. DOE/PETC, is conducting a conceptual design study to evaluate a coal-fired magnetohydrodynamic (MHD) retrofit of a utility plant of sufficient size to demonstrate the technical and future economic viability of an MHD system operating within an electric utility environment. The objective of this study is to prepare a site-specific conceptual design of a coal-fired MHD system or retrofit to the Scholz Generating Station, Sneads, Florida. The objective of this technical paper is to document continuing seed regeneration system application studies and the definition of seed system integration requirements for the Scholz MHD retrofit plant design. Development of a seed regeneration process with the DOE MHD Proof-of-Concept program is being accomplished by the TRW Applied Technology Division. This TRW program included the definition of a design basis for an ECONOSEED process suitable for a 300 MWt coal-fired MHD power plant. The 300 MWt ECONOSEED design basis was used to prepare a mathematical model for quantifying interface requirements between the Scholz MHD retrofit plant design and an integrated ECONOSEED regeneration system. The mathematical model was validated by comparison with the ECONOSEED 300 MWt design basis and includes: (1) Capital, operating, maintenance, and consumable cost, (2) Cost algorithms for the seed regeneration system and the seed injection system to permit evaluations of capital and operating costs as a function of plant size and operating conditions. As expected, the most significant cost driver for the seed regeneration system is the coal sulfur content and therefore the amount of sulfur that the seed system removes from the process. The seed system operating cost in mills/kWh is also sensitive to the overall power plant efficiency.
