This feature has made thermionics an attractive choice for space power systems; and it has substantial potential for terrestrial advanced energy conversion, if certain recently identified technological developments are realized in a low cost manner. Thermionic energy converters are well suited to a modular approach. Thermionics is a passive system without moving parts. Recently it has been shown that close spaced thermionic converters can achieve the performance goals necessary to meet attractive new terrestrial power applications. The paper addresses the progress in this regard and describes approaches for engineering practical closed spaced converters for large scale applications. Clearly the potential for thermionic energy conversion is great. Every effort must now be made to use this technology to help solve the world's energy problems. Investments in the manufacturing infrastructure necessary to make thermionic energy conversion cost effective are needed to reach this goal.","PeriodicalId":183668,"journal":{"name":"IECEC-97 Proceedings of the Thirty-Second Intersociety Energy Conversion Engineering Conference (Cat.

The study provided a comparison of performance, CO/sub 2/ emission, capital cost, cost of electricity, and cost of avoiding CO/sub 2/ emission among four atmospheric, or near atmospheric, molten carbonate fuel cell/CO/sub 2/ capturing plants (fueled with either coal or natural gas). Each fuel cell combined cycle plant with CO/sub 2/ capture was compared with a similarly-sized reference combined cycle plant without CO/sub 2/ capture to develop comparison characteristics. Data for the reference plants were taken from previously completed IEA studies. The first reference plant was a coal-fueled integrated gasification combined cycle (IGCC). This plant features an oxygen-blown, entrained-bed gasifier providing fuel gas to a commercially available gas turbine. Waste heat is recovered and utilized in a steam turbine bottoming cycle. The second reference plant was a typical natural gas-fueled gas turbine combined cycle.","PeriodicalId":183668,"journal":{"name":"IECEC-97 Proceedings of the Thirty-Second Intersociety Energy Conversion Engineering Conference (Cat.

The choice among these systems depends from the specific site conditions such as dust characteristics, required efficiency, gas flowrate and temperature. ESP are generally characterized by higher capital investments and lower operating charges, while the opposite may be said for baghouses. As a consequence, ESP present higher total costs when high specific collection areas are required, as happens in the case of low-sulfur high-resistivity dust. However, significant reductions in both capital investment and operating charges may be obtained with pulsed energization of precipitators working in severe back corona conditions. This possibility greatly enlarges the field of applications in which ESP are a lower cost option compared to fabric filters. In the paper an economic comparison of pulse energized ESP, with conventional ESP, reverse-air, shaker and pulse-jet baghouses is performed. A mapping of the operating conditions in which the adoption of each examined control technology is economically convenient is also defined.","PeriodicalId":183668,"journal":{"name":"IECEC-97 Proceedings of the Thirty-Second Intersociety Energy Conversion Engineering Conference (Cat.

APEAM incorporates an axial electrochemical model, which accounts for the effects of nonuniform axial temperature and vapor pressure profiles along the BASE tubes; a detailed vapor pressure loss model, which includes free-molecular, transition and continuum flow regimes; and a comprehensive radiation/conduction model, which incorporates the effects of circumferential thermal shields above the BASE tubes and conduction studs between the hot end of the cell and the tubes support plate. Model results compared well with measured electrical power and experimental I-V characteristics of the PX-2C cell, recently tested at Phillips Laboratory. The cell peak electric power of 4.4 We occurred at an external load resistance of 3.0 /spl Omega/. At higher load resistance (or lower load demand), the PX-2C cell was load-following. Results also showed that the vapor flow on the low-pressure side of PX-2C was in the transition regime. The evaporator wick provided the sodium flow rate (8 g/hour) necessary to operate the cell at an evaporator temperature of about 950 K. The model predicted that using a molybdenum thermal shield on the inside of the cell wall, near the condenser, would increase the cell electric power and conversion efficiency by /spl sim/23%.","PeriodicalId":183668,"journal":{"name":"IECEC-97 Proceedings of the Thirty-Second Intersociety Energy Conversion Engineering Conference (Cat.
