MULTIFUELED THERMAL-ENERGY-CONVERSION SYSTEMS.

Abstract

Design studies of 150-watt power sources of simple design, fired with a variety of solid fuels, show that Stirling-cycle unit of 3.1% efficiency should weigh about 22 kg, and a Rankine-cycle unit of 5.7% efficiency should weigh about 15 kg. Efficiencies are bn electric-power output and fuel heating value. Studies of a thermoelectric generator based on Ge-Si technology are incomplete, but indicate that a unit of 3% efficiency should weigh about 5 kg. A simulated thermoelectric generator under test was modified, following which rated heat absorption rates of 3 kw th were obtained with all fuels. A survey of coal types found in less developed areas showed that almost all of the coal available is free burning and, thus, suit able for use in burners under study. (Author)
