ABSTRACT:
A cylindrical TPV generator uses low bandgap PV cells mounted on circuits in a polygonal array around an IR emitter. A low NOx radiant tube burner enables operation at low NOx. The combustion gases are completely contained within the radiant tube burner. A gap is provided between a recuperator and an inner flame tube of a dual tube SiC folded back recuperator assembly. Preheating combustion air in the recuperator allows for flameless oxidation. The gap allows for exhaust gas recirculation to complete combustion. The PV array is mounted inside a leak-tight envelope cooled on its outer surface by either water or air flow. Flanges on either end of this PV array container allow for hermetic seals. A folded back coaxial emitter support tube provides a long path length limiting thermal conduction along its cylindrical wall from the very hot emitter section to the cooled seal flange.
