  • Liquid hydrocarbon-fueled thermo-electric generator with counter-flow type regenerative heat exchanger
    Patent number: 4218266
    Abstract: An air-to-air heat exchanger, comprising an array of stainless steel tubi arranged in a three-fold pass, is connected to the outlet of the combustion chamber of a liquid hydrocarbon-fueled, thermoelectric generator. Air enters the heat exchanger at the ambient temperature and is pre-heated up to 500.degree. C. At the same time, the temperature of the gases leaving the combustion chamber is reduced from 700.degree. C. to only 200.degree. C. This pre-heating of the air reduces fuel consumption, increases efficiency and makes it more difficult to detect the generator by means of its infrared signature.
