<p>A combustion furnace (40) providing circulating hot fluid heating has a thermoelectric generator comprised of a plurality of thermoelectric modules (52). Combustion heat provides a high temperature heat source for the modules and the fluid of the circulating hot fluid system provides a heat sink for the modules. Electric power produced by the modules powers a motor driving a pump (48) which circulates the circulating hot fluid. Preferably, the modules comprise thermoelectric elements installed in injection molded eggcrates. A spring force such as that provided by Belville springs holds the modules in close contact with the heat source and the heat sink. The eggcrate is molded from a high temperature plastic. Ridges provide extra strength. Tapered walls permit easy installation of the elements. Stop tabs (10) assure correct positioning of the elements.</p> |
