These heat shields essentially lower the radiative heat transfer between the heat input zone of the cell and the heat rejection zone of the cell. In addition to lowering the radiative heat transfer between the heat input and heat rejection surfaces of the cell, the shields raise the AMTEC cell performance by increasing the temperature of the beta'' alumina solid electrolyte (BASE). This increase in temperature of the BASE tube allows the evaporator temperature to be increased without sodium condensing within the BASE tubes. Experimental testing and theoretical analysis have been performed to compare the relative merits of two candidate heat shield packages: 1) chevron, and 2) cylindrical heat shields. These two heat shield packages were compared to each other and a baseline cell which had no heat shields installed. For the two heat shield packages, the reduction in total heat transfer is between 17% to 27% for the heat input surface temperature varying from 700/spl deg/C, 750/spl deg/C, and 800/spl deg/C with the heat rejection surface temperature kept at 300/spl deg/C.","PeriodicalId":183668,"journal":{"name":"IECEC-97 Proceedings of the Thirty-Second Intersociety Energy Conversion Engineering Conference (Cat.

In order to reduce energy consumption, considerable studies have been carried out and many distillation columns have been proposed. A heat-integrated distillation column (HIDiC) is constructed in such a manner that its rectifying and stripping sections are separated, while connected through a compressor and a throttling valve. Separation is benefited by heat integration between the two sections. To provide the driving forces for heat transfers from the rectifying to the stripping sections, the former must be operated at a higher pressure than the latter. The HIDiC is expected to be more energy efficient than conventional columns, while at the expenses of some energy to raise up the pressure of the rectifying section. In this paper, it is shown by thermodynamical consideration that the HIDiC has high potential of energy loss reduction compared with conventional columns. The effects of pressure difference on energy saving are analyzed, and possibility of energy saving is found in some case studies.","PeriodicalId":183668,"journal":{"name":"IECEC-97 Proceedings of the Thirty-Second Intersociety Energy Conversion Engineering Conference (Cat.

Such substances, generally referred to as emissions (acid gases, nitrogen oxides, particulate, micropollutant of different origin, etc.), show specific effects upon the ecosystem and need therefore to be kept under control. As a consequence, standards, rules, and regulations have been introduced to limit, in certain ways, the admissible concentrations. This fact from one side has brought to development of control systems based upon gas cleaning after combustion, and from the other has introduced the need to modify the combustion process in order to minimize the production of pollutants. This latter aspect of the problem is specifically considered in this paper. After a general discussion about criteria employed to contain emissions, the influence upon the process of a specific parameter, namely turbulence, is analyzed. Emphasis is given to the fundamental role of this parameter in order to optimize the process; evidence is also given to how the introduction of more severe rules brings as a consequence the need to modify turbulence parameters in order to meet the required standard emissions. A model is introduced to allow to relate the turbulence parameters to the required emissions concentrations. Such a relation allows the designer of the combustion system to meet the required standards. Particular evidence is given to the fact that, when very low emission levels are imposed, high turbulence levels are required in order to optimize the process.","PeriodicalId":183668,"journal":{"name":"IECEC-97 Proceedings of the Thirty-Second Intersociety Energy Conversion Engineering Conference (Cat.

This improvement in performance which is especially pronounced at operational equivalence ratios that are much leaner than the stoichiometric value, can be attributed largely to the faster and cleaner burning characteristics of hydrogen in comparison to methane. Through analytical simulation of engine performance, the addition of hydrogen is considered through its production in-situ on board the engine by electrolysis of water with the necessary energy supplied from engine power. It is shown that when the work energy required for the production of hydrogen by electrolysis is taken into account, the range of viable operation of such an engine is very narrow. This would render the whole concept of in situ hydrogen production through water electrolysis uneconomical in conjunction with engine operation, even though the presence of additional oxygen produced with the hydrogen tends, in principle, to improve engine performance beyond that observed with hydrogen addition.","PeriodicalId":183668,"journal":{"name":"IECEC-97 Proceedings of the Thirty-Second Intersociety Energy Conversion Engineering Conference (Cat.
