Thermodynamic Characteristic of Cogeneration Installations with Thermoelectric Heat Recuperator

Abstract

The problem of heat recovery from cogeneration installations using thermoelectric generators is of great interest due to steady-state operation of the installations. A theoretical basis for the design of thermoelectric generators used for cogeneration installations has been formed. Fundamental relations used for estimation of the electrical power and efficiency of such generators in different model approximations are given. The main regularities of the generator operation, such as optimal thermal modes, the correlation between heat flows at the inlet and outlet of the generator, as well as thermoelectric materials requirements are established.
