摘要: Abstract In this paper, a computational study of the influence heat exchangers' thermal resistances (in both hot and cold side) on efficiency thermoelectric generation device has been carried out. For purpose, model developed. This uses numerical method finite differences to simulate performance system, including exchangers, source sink. The accuracy was experimentally verified, by constructing testing prototype. It obtained that maximum error between experimental simulated values electric power generated is lower than 5%. power, using as smoke from paper mill's combustion boiler, studied too. results demonstrated it possible generate about 1 kW per meter chimney height, is, 300 W/m 2 . Therefore, can be stated good prospects for future.
