DESIGN STUDY FOR ADVANCED SOLAR THERMIONIC POWER SYSTEMS. ITEM II. PART I. VAPOR TYPE THERMIONIC GENERATOR
Abstract
A survey of the state of the art of thermionic power generation was carried out as part of a design study for advanced solar thermionic power systems. The results are reported and serve as a basis for the preparation of a detailed design and test specification for two laboratory test models of thermionic generators. Part I of the report pertains to the Vapor Type Thermionic Generator, and Part II (AD-260 066) pertains to the Close-Spaced Vacuum Thermionic Generator. Part I describes the results of a design study on vapor type thermionic converters and establishes the design and test specifications for a laboratory test model Cs thermionic converter. The unit is rated at 28 volts, 250 watts electrical power output and consists of 2 identical Cs converters connected in series. The series combination voltage of 2.8 volts is converted to the specified 28 volts by an 80% efficient dc-dc transistorized converter. The gross power output from each Cs converter is 156 watts.
