Book Description
The overall objectives of this program are the design, fabrication and delivery of test channels (nozzle, channel, diffuser, instrumentation and controls, and all necessary facility service connections) to the CDIF (Component Development and Integration Facility) for MHD generator tests. These CDIF test channels will be driven by a coal combustor which is under development at PERC in parallel with this program. Progress is reported on the following tasks: (1) Conduct basic engineering tests and perform necessary analytical work to define preferred design configurations of the CDIF channel in relation to fluid dynamics and electrodynamic performance. (2) Conduct basic engineering tests and perform necessary analytical work to define preferred electrode module design, side wall construction, wall materials, and fabrication methods for a high performance, durable MHD channel. (3) Conduct basic engineering tests and perform necessary analytical work to define instrumentation and controls and preferred inverter systems and/or channel electrical controls in relation to inverter requirements and operating stability. (4) Determine basic performance capability of the disk generator design under conditions simulating an open cycle MHD plasma. (5) Maintain continuous design and engineering liaison with the Pittsburgh Energy Research Center (PERC) in the development of the two stage CDIF coal combustor. Ensure design compatibility of the integrated combustor-generator system. Design, build, and deliver to PERC an instrumented test section to assist in the design and performance evaluation of the PERC subscale 5 MWt experimental combustor. Obtain quantitative chemical and physical data on relevant coal slags with the PERC experimental combustor. (6) Conduct necessary bench tests to establish essential design information on fluid dynamic, heat transfer, and current transfer characteristics of selected MHD coal slags.
