Title: FIRED HEAT EXCHANGER WITH A THERMOELECTRIC GENERATOR
Abstract:
The fired heat exchanger intended for central heating and/or domestic water installations, having a thermoelectric generator, the functioning of which is based on the Seebeck effect, and fitted with an external jacket, combustion chamber, and flame pipes fixed in the sieve bottoms, according to the invention is characterised in that the thermoelectric generator takes the form of a thin thermoelectric coating (13) applied under the PVD (Physical Vapour Deposition) technology to these elements of the heat exchanger which are in thermal contact with combustion gases, where the coating contains a thermoelectric layer (1) having two semiconductor sub-layers 'p' and 'n' which do not contact each other and are interconnected in series with thin-layered conducting elements (2a, 2b) fitted with connection ends (4, 5) to evacuate the generated electric energy, and where the coating is electrically insulated on both sides with layers (3a, 3b) of electrical insulator based on inorganic oxides.
