Description of the DOE Coal-Fired MHD Flow Facility /CFFF/
Abstract
Components, instrumentation, and operating parameters of the DOE MHD Coal-Fired Flow Facility are described, noting its extension and expansion from a previous prototype plant. The CFFF features three bays for coal delivery, offering hot gas flows of 8 and 30 lb/sec, and a third rate for outside contractor studies. A Low Mass Flow test train is intended for engineering tests of component performance, durability, and scaling parameters. An oxygen-rich gas composed of oxygen, nitrogen, and No. 2 fuel oil will be heated to 1283 K for mixing with pulverized coal, a carrier gas, and a seed material such as potassium carbonate and/or potassium sulfate and burned substoichiometrically to produce an ionized gas. The gas flow is routed through a diagnostic channel to determine the MHD output, plasma uniformity, and gas dynamic conditions. Further systems for slag removal, pollution control, magnetic field generation, and data acquisition are detailed.
