Characterization of Open-Cycle Coal-Fired MHD Generators. Quarterly Technical Summary Report No. 2, October 1--December 31, 1976. [Negative Ion Formation, Electron/Slag Interaction, and Alkali/Slag Interaction]
A study on how nonfuel components of coal will affect the electron and alkali seed chemistry in a high temperature coal combustion system like those envisioned for direct fired MHD generators is described. Three specific problems are being considered. The first problem area is to characterize the formation of negative ions due to electron attachment processes in the combustion flow. While some stable negative ions may be formed from hydrocarbon combustion species (OH, HCO/sup -//sub 3/), the bulk of the stable negative ions are expected to be formed from oxidized inorganic coal slag constituents (CO/sup -//sub 2/, PO/sup -//sub 2/, AlO/sup -//sub 2/, etc). Negative ion formation can reduce the conductivity of the MHD plasma, particularly at the low temperature end of the MHD channel, thus decreasing the efficiency of power generation. This phenomena is expected to be particularly severe in electrode boundary layers, and particular attention will be paid to conditions characteristic of flow along the electrodes. The second problem area involves the role slag condensation may play in determining the electron density through recombination, also adversely affecting conductivity in the core flow. The competitive balance between thermionic emission from slag droplets and electron/ion recombination on the droplet surfaces …
