RAM IIB was part of a continuing Reliability, Availability, and Maintainability (RAM) program, the purpose of which is to demonstrate the KILnGAS technology. RAM IIB began in March 1987 and concluded in April 1988, and was preceded by RAM I and RAM IIA. These prior segments including engineering to design and incorporate improvements in the KILnGAS Commercial Module (KCM), and were followed by demonstration tests. RAM IIB, by contrast, was primarily engineering-oriented. In-depth engineering analysis of RAM IIA test results was performed during RAM IIB. It was concluded that substantial progress had been made as a result of RAM IIA testing, and that previous unknowns relative to commercial risks had been greatly reduced. These findings provided the basis for identifying future development needs and the KILnGAS Technical Committee issued a report providing commercial improvement recommendations. The majority of the recommendations were design-related since prior technology-oriented issues had now been largely answered. Preliminary designs were developed for four KCM improvements that could be used in commercial applications as well. These were: improved air-steam porting, recycle of carbon losses, a more reliable ash-discharge system, and improved gasifier dust seals. Each of these was a factor in limiting either KCM availability, gas production, or conversion efficiency during RAM IIA. A ''first plant'' KILnGAS-based commercial plant concept was developed for a Gasification Combined-Cycle (GCC) application. Performance features, capital investment, and power generation costs were developed for a 400 MW plant. Since RAM IIB did not include an operational phase, the KCM was placed in a ''protected'' condition, and periodic maintenance was performed to assure restart capability. 33 figs., 6 tabs.
