Abstract
A thermophotovoltaic generator uses conveniently available liquid hydrocarbon fuels. The fuels are controllably heated and vaporized before ignition to avoid residue and deposits as a result of liquid fuel being prematurely exposed to high temperatures of combustion causing unwanted breakdowns, producing power robbing residues and deposits. Heating fuel and air to right temperatures for ignition is accomplished by drawing combustion air over an exhaust chamber, through a regenerator and through a passage surrounding an IR filter. A separate cooling fan drives air through photovoltaic cell array fins over the recuperator and the exhaust in counterflow to the combustion air.
