ABSTRACT:
The objectives of the Second Symposium on Valves for Coal Conversion and Utilization were:
• To inform the valve industry of the application requirements and needs for severe-service valving in the emerging synthetic-fuels technologies.
• To establish the state of the art with valving in these severe-service applications by discussing user experience.
• To establish a forum for technical information interchange between valve manufacturers, users, specifiers, and the Government relative to the severe-service valves required for coal conversion.

The Symposium program consisted of the presentation of 15 papers on a wide range of topics related to valves for coal-conversion service and two panel discussions--one on block valves and one on throttle valves. The presentations--made by experts in the coal-conversion field--were excellent with active audience participation during the question-and-answer sessions. Hopefully, the exchange of information that took place among participants during the Symposium and during follow-up exchanges will result in a better understanding for all participants--valve manufacturers, users, and specifiers--of the many problems that are inherent in the multitude of processes involved in the emerging coal-conversion industry.… (altro)

ABSTRACT:
The purpose of this electric utility study was to develop and apply a methodology for assessing ERDA powerplant and transmission system technologies that may be used by the utility industry. This report covers
the first phase of the study in which the ERDA R,D&D program objectives for each technology in terms of capital and maintenance costs, efficiency, and development schedule were used as basic inputs. Therefore, this report is a relative assessment of technologies under the assumption that all such program objectives will be successfully achieved. The assessment criteria are based primarily on the cost perspective of the utility industry with some additional consideration of national benefits. This report does not attempt to assess any of the ERDA programs in applications other than the electric utilities. As a consequence, ERDA programs that have additional applications in other sectors are not fully assessed. These program areas (i.e., synfuels, advanced coal combustion, solar, geothermal, and energy storage) may be equally or even more important when considered in transportation, space heating and cooling, and other industrial uses. Although a technology may be an intermediate step in the development of another technology, this possibility has been disregarded. Each technology in this study is considered a candidate for commercialization by the electric utility industry on its own merits and without additional government incentives.… (altro)
