THE DEVELOPMENT OF A FLAME FIRED THERMIONIC GENERATOR.
Abstract
The report covers a seven month program to investigate components for flame fired thermionic energy conversion systems. The objective of the program is to demonstrate the feasibility of integrating a thermionic converter with a barrier layer and a heat pipe to obtain 1500 hour reliability of the assembly. A basic subassembly was designed to deliver 100 electrical watts from the thermal energy of a fossil fuel flame operating in an air environment. Twelve of these units would be used in the one kilowatt power module. Problems of heat transfer, permeation barrier integration, heat pipe processing and closure and burner temperature uniformity were encountered and substantially reduced or eliminated. The separate components were evaluated and determined to be satisfactory. It still remains to evaluate the complete assembly by life testing from a fossil fuel flame for a period up to 1500 hours.
