Pyrochemical Themionic Heat Source Investigation

Abstract

The report describes a feasibility study of a chemically fueled thermionic generator and includes a study of pyrochemical fuels for this generator. The program consisted of three tasks: heat source study, materials compatibility study, and system conceptual design. System performance goals were that the generator should have a capability of from 1 to 100 kW with a minimum specific energy of 100 W-hr/lb for up to 30 minutes. Fuel preparation and processing are specified and the characteristics of three fuel combinations (Al/ KCl04, Mg/KCl04, and Mg/Teflon) were measured. A solid bed fuel or a slurry fuel system is recommended. Vapor-deposited rhenium was chosen as the combustion chamber material. (Author)
