<p>A linear combustion emitter regenerator process capable of operating at high temperatures for sustained periods of time, that includes flowing reactants including fuel and air to a combustion zone (17); adding regenerated heat to at least one of the reactants flowing to the zone; combusting the reactants at the zone to produce combustion products at high temperature, to heat radiant emitter (170); operating the emitter to radiate energy from the zone passing selective wavelengths of said radiated energy spectrum through an optical filter and converting the radiation from the emitter into photovoltaic-produced electricity; mounting optical filter on water-cooled window (38) to act as a heat shield to protect photovoltaic cells from overheating; reflecting back to the emitter (170) portions of the spectral emission not able to activate the photovoltaic cells; extracting heat absorbed by liquid-cooled window (38) by means of a heat exchanger to transfer heat to incoming combustion air; extracting heat from the combustion products for return to at least one of the reactants as the recuperated heat; removing the products of combustion at reduced temperature; and providing a porous bed (20) at and to which the extracted heat is transferred; and periodically reversing the direction of flow of at least one of the reactants; and in heat transfer contact with the bed.</p> |
