Efficiency Estimation of Thermoelectric Generators Application in the Liquefied Natural Gas Gasifiers

The object of the research is a thermoelectric generator installed in a liquefied natural gas gasifier. In this article the numerical estimation of parameters of thermoelectric generators (TEG) at cryogenic temperatures are presented and the experimental study of the thermoelectric properties of TEG at low temperatures as well as the outlook for using thermoelectric generators as a part of industrial liquefied natural gas gasifier has been carried out. In the process used heat transfer theory of cylindrical thin wall with a one-sided fins and the estimation of thermoelectric performance of TEG. As a result the experimental work has been investigated by TEG parameters at cryogenic temperatures; the evaluation of TEG number to produce electrical energy has been considered.
