Abstract

See full text

An emitter for use with a generator has a tube closed at one end, heated from its outside with a water-cooled photovoltaic converter array mounted inside for glass-melting application. Several TPV tubes may be inserted through holes in the insulation into the port sections between the glass-melting furnace and the regenerators. Any one of these tubes may be removed for maintenance at any time and replaced with a closure to close off the hole, without affecting the industrial process. The emitter tube may be a SiC or KANTHAL tube. The tube may be lines on its inside with AR coated tungsten foil or the tungsten may be deposited on the inner tube surface as a film followed by the AR coating. The photovoltaic converter array may comprise a polygonal array of shingle circuits where the circuits are fabricated using low bandgap GaSb cells.
