Development, Testing, and Evaluation of MHD Materials and Component Designs. Volume I. Executive Summary. Final Report, 15 October 1973-31 December 1975

摘要

This report comprises seven volumes, one for each of the major tasks, an appendix volume and the executive summary. The tasks on gas electrical properties, coal combustion, and MHD materials were intended to support the Waltz Mill channel experiments. The conductivity apparatus indicated abnormally high values. The experiments were continued in the Waltz Mill facility. Materials testing indicated that stabilized zirconia should be an acceptable electrode material. A new and improved test facility was designed. Cyclone coal combustors were studied and designs developed for a Waltz Mill size unit and a 25,000 lb/h prototype. The Waltz Mill facility performed in a highly satisfactory manner. Six non-generating and 16 load tests were made on three channels. Following a failure of the air heater tests were run essentially on materials and structures; little power was generated. Electrical leakage, interelectrode and to ground, was a persistent problem. Following the last load test on October 25, 1976, the system was dismantled and reconstruction started to enable testing at the proposed CDIF (Component Development Integrated Facility) conditions (part of the national MHD program). A very successful 127-hour run was made on a pair of US designed and constructed MHD electrode modules in the Soviet Union's U-02 facility, completing Phase I of the US/USSR Cooperative program.
