Book excerpt: The conceptual design study of a potential early commercial MHD power plant (CSPEC) is described and the results are summarized. Each of two contractors did a conceptual design of an approximtely 1000 MWe open-cycle MHD/steam plant with oxygen enriched combustion air preheated to an intermediate temperatue in a metallic heat exchanger. The contractors were close in their overall plant efficiency estimates but differed in their capital cost and cost of electricity estimates, primarily because of differences in balance-of-plant material, contingency, and operating and maintenance cost estimates. One contractor concluded that its MHD plant design compared favorably in cost of electricity with conventional coal-fired steam plants. The other contractor is making such a comparison as part of a follow-on study. Each contractor did a preliminary investigation of part-load performance and plant availability. The results of NASA studies investigating the effect of plant size and oxidizer preheat temperature on the performance of CSPEC-type MHD plants are also described. The efficiency of a 1000 MWe plant is about three points higher than of a 200 MWe plant. Preheating to 1600 F gives an efficiency about one and one-half points higher than preheating to 800 F for all plant sizes. For each plant size and preheat temperature there is an oxidizer enrichment level and MHD generator length that gives the highest plant efficiency. Staiger, P. J. and Penko, P. F.

Available in PDF, EPUB and Kindle. Book excerpt: Because of the close relationship between the ETF design work conducted under this contract, and the design work of Potential Early Commercial MHD Power Plants (PSPEC) conducted under a separate and parallel DOE/NASA study contract, (DEN 3-51), the ETF design work reported on here was coordinated as far as possible with the design information developed in the above-mentioned separate PSPEC study. The reference power system configuration originally specified for the ETF considered the use of a high-temperature-air preheater, separately fired initially with oil and subsequently with a LBtu gas produced in a coal gasifier integrated with the power plant. The potential attractiveness of using oxygen enrichment in combustion of the coal for early commercial MHD power plant applications was indicated in our original ETF Conceptual Design Document. This eliminates the need for a high-temperature-air preheater and its associated gasifier. The results from our initial parametric design analysis in the separate study of Early Commercial MHD Power Plants reinforced the potential attractiveness of the use of oxygen enrichment of the combustion air. Therefore, preliminary analysis of the use of oxygen enrichment for the ETF was included as part of the ETF contract amendment work reported on here.
