Book excerpt: Progress continued at MHD coal-fired flow facility. UTSI reports on progress in developing the technology for the steam bottoming portion of the MHD Steam Combined Cycle Power Plant. No Proof-of-Concept (POC) testing was conducted during the quarter but data analyses are reported from the test conducted during the prior quarter. Major results include corrosion data from the first 500 hours of testing on candidate tube materials in the superheater test module (SHTM). Solids mass balance data, electrostatic precipitator (ESP) and baghouse (BH) performance data, diagnostic systems and environmental data results from previous POC tests are included. The major activities this quarter were in facility modifications required to complete the scheduled POC test program. Activities reported include the installation of an automatic ash/seed removal system on the SHTM, the BH, and ESP hoppers. Also, a higher pressure compressor (350 psi) is being installed to provide additional blowing pressure to remove solids deposits on the convective heat transfer tubes in the high temperature zone where the deposits are molten. These activities are scheduled to be completed and ready for the next test, which is scheduled for late May 1990. Also, experiments on drying western coal are reported. The recommended system for modifying the CFFF coal system to permit processing of western coal is described. Finally, a new effort to test portions of the TRW combustor during tests in the CFFF is described. The status of system analyses being conducted under subcontract by the Westinghouse Electric Corporation is also described. 2 refs., 18 figs., 3 tabs.

Book excerpt: In this quarterly technical progress report, UTSI reports on progress on a multitask contract to develop the necessary technology for the steam bottoming plant of the MHD Steam Combined Cycle power plant. A Proof-Of-Concept (POC) test was conducted during the quarter and the results are reported. This POC test was terminated after 88 hours of operation due to the failure of the coal pulverizer main shaft. Preparations for the test and post-test activities are summarized. Modifications made to the dry electrostatic precipitator (ESP) are described and measurements of its performance are reported. The baghouse performance is summarized, together with actions being taken to improve bag cleaning using reverse air. Data on the wet ESP performance is included at two operating conditions, including verification that it met State of Tennessee permit conditions for opacity with all the flow through it. The results of experiments to determine the effect of potassium seed on NO(subscript x) emissions and secondary combustion are reported. The status of efforts to quantify the detailed mass balance for all POC testing is summarized. The work to develop a predictive ash deposition model is discussed and results compared with deposition actually encountered during the test. Plans to measure the kinetics of potassium and sulfur on flames like the secondary combustor, are included. Advanced diagnostic work by both UTSI and MSU is reported. Efforts to develop the technology for a high temperature air heater using ceramic tubes are summarized.

This book was released on 1996 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of coal-fired magnetohydrodynamic (MHD) power can be viewed as consisting of two parts; the topping cycle and the bottoming cycle. The topping cycle consists of the coal combustor, MHD generator and associated components. The bottoming cycle consists of the heat recovery, steam generation, seed recovery/regeneration, emissions control (gas and particulate), ash handling and deposition, and materials evaluation. The report concentrates on the bottoming cycle, for which much of the technology was developed at the University of Tennessee Space Institute (UTSI). Because of the complexity of the required technology, a number of issues required investigation. Of specific concern regarding the bottoming cycle, was the design of the steam cycle components and emissions control. First, the high combustion temperatures and the use of large quantities of potassium in the MHD combustor results in a difference in the composition of the gases entering the bottoming cycle compared to conventional systems. Secondly, a major goal of the UTSI effort was to use a variety of coals in the MHD system, especially the large reserves of high-sulfur coals available in the United States.

Available in PDF, EPUB and Kindle. Book excerpt: Significant activity, task status, planned research, testing, development, and conclusions for the Magnetohydrodynamics (MHD) Coal-Fired Flow Facility (CFFF) and the Energy Conversion Facility (ECF), formerly the Research and Development Laboratory, are reported. CFFF Bid Package construction is now virtually complete. The remaining construction effort is being conducted by UTSI. On the quench system, another Task 1 effort, the cyclone was erected on schedule. On Tasks 2 through 6, vitiation heater and nozzle fabrication were completed, an investigation of a fish kill (in no way attributable to CFFF operations) in Woods Reservoir was conducted, major preparation for ambient air quality monitoring was made, a broadband data acquisition system for enabling broadband data to be correlated with all general performance data was selected, a Coriolis effect coal flow meter was installed at the CFFF. On Task 7, an analytical model of the coal flow combustor configuration was prepared, MHD generator testing which, in part, involved continued materials evaluation and the heat transfer characteristics of capped and uncapped electrodes was conducted, agglomerator utilization was studied, and development of a laser velocimeter system was nearly completed.

This book was released on 1994 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this quarterly technical progress report, UTSI reports on progress in developing the technology for the steam bottoming portion of the MHD Steam Combined Cycle power plant. The experimental program was effectively terminated and reoriented to preparation of reports on previous tests and maintaining the DOE facility. In this report, the results of tube corrosion studies for the samples removed after 500 hours of western coal testing are summarized. Plans for evaluating the tube samples after termination of the tests at 1,047 hours are discussed. The status of development of models to predict ash deposition on conductive heat transfer tubes and their validation with experimental data is presented. Modeling and experiments to induce agglomeration of particulate are also discussed. Significant accomplishments, findings and conclusions include: In summary, corrosion measurements on typical, commercial stainless steels and on low and intermediate chromium steels after 639 hours of LMF5 exposure in the SHTM test sections revealed corrosion that was generally acceptable in magnitude if corrosion kinetics are parabolic, but, except for the higher chromium alloys 253MA and 310, not if kinetics are linear. The production of bilayer scales, and the large amount of scale separation and fragmentation make long term parabolic kinetics unlikely, and result in a high likelihood for breakaway corrosion.

Book excerpt: The University of Tennessee Space Institute (UTSI) reports on significant activity, task status, planned research, testing, development, and conclusions for the Magnetohydrodynamics (MHD) Coal-Fired Flow Facility (CFFF) and the Research and Development Laboratory. Although slowed by incessant rain during several days, work on the CFFF Bid Packages progressed to nearly 100 percent completion, excluding later punchlist items. On the quench system, the cyclone separator was delivered to UTSI, and under Downstream Components, the secondary combustor was received and the radiant slagging furnace was emplaced at the CFFF. Water quality analysis of Woods Reservoir provided the expected favorable results, quite similar to last year's. Generator experiments describing local current distribution are reported along with behavior under conditions of imposed leakage. Also, during the Quarter, the shelter for the cold flow modeling facility was constructed and circuits installation begun. A jet turbine combustor was tested for use as a vitiation burner. Samples taken from the exhaust duct, besides other applications, show that the refractories used are performing well in alleviating heat loss while exhibiting acceptable degredation. A new resistive power take-off network was designed and implemented.
