DOE advanced thermionic technology program. Progress report No. 46, January, February, March 1981
The primary long-term goal is to improve thermionic performance to the level that thermionic topping of fossil-fuel powerplants becomes technically possible and economically attractive. An intermediate goal is to operate a thermionic module in a powerplant during the mid-1980's. A short-term goal is to demonstrate reliable thermionic operation in a combustion environment. This report covers progress made during the three-month period from January through March 1981. During this period, significant accomplishments include: (1) continuing stable output from the combustion test of the one-inch diameter hemispherical silicon carbide diode at an emitter temperature of 1730 K for a period of over 6400 hours; (2) demonstration of an additive oxygen effect in a research diode with a cesium-graphite reservoir located in the collector; (3) preliminary testing of the four-diode module; and (4) evaluation of a research diode with ZrO/sub 2/-Mo cermet electrodes.
