THERMIONIC CONVERTER RESEARCH.
Abstract
Arc-mode converter operation and the performance of solid ion-emitters were investigated for application to low-temperature thermionic converters which can produce reasonable power densities at temperatures compatible with combustion heat sources. Iridium was found to be the best emitter material investigated. Aconverter with an iridium emitter produced 4.5 W/sq cm at 1377 C emitter temperature, and a converter with a rhenium emitter produced 4.5 W/sq cm at 1405 C. Converters with molybdenum emitters were found to have an initial power output which depends on the contamination in the system, and during the first few days of operation, the power output degrades to a stable value. The operation of a converter with a Philips ''B'' emitter was found to be strongly influenced by an auxiliary electrode. (Author)
