MHD Integrated Topping Cycle Project. Twenty-first quarterly technical progress report, August 1, 1992--October 31, 1992

摘要

Combustor spare and contingency hardware was shipped to the CDIF. Manufacture of spare and replacement hardware for the lA4 channel and diffuser continued. Fabrication of a modified/spare channel inlet frame which enables iron oxide injection. The cathode power cabinets and associated control system were successfully tested at Westinghouse and met all design requirements. The cathode system was delivered to the CDIF and installed in the current consolidation building. With the delivery of tills component, all prototypical power train components have been delivered to the CDIF. The hot-fire checkout of the channel subsystem and the design verification test series of the integrated power train were completed. A total of 29 tests were performed accumulating 120 thermal and 52 electrical hours. The test series demonstrated the adequacy of the overall cooling of the channel subsystem and provided an initial evaluation of the integrated combustor and channel performance in terms of operating conditions, power output, conductivity, heat loss, slagging behavior, and gas-side wear characteristics. During the test series localized wear in the supersonic nozzle was observed on the right sidewall. Cause of wear is being investigated. At conclusion of DVT test series, the channel was removed for inspection.
