Abstract McDermott Technology, Inc. (MTI) and JX Crystals (JXC) are developing a portable thermophotovoltaic (TPV) electric generator under a Defense Advanced Research Projects Agency (DARPA) contract. The contract is managed by the U.S. Army's Communication and Electronic Command (CECOM) due to its interest in the device for field applications. The generator is designed to burn diesel fuel (DF-2) at an overall efficiency of 8% -10% and net output of 500 watts DC power. MTI is developing the burner/emitter/recuperator (BER), which converts chemical energy in the fuel to a uniform radiant heat flux directed toward the photovoltaic cells. A thermally integrated, high-temperature recuperator was used to increase fuel efficiency by preheating the combustion air. The power converter assembly (PCA) developed by JXC converts the radiant flux that emanates from the emitter to electrical power using an array of photovoltaic cells. This paper describes the burner development work at MTI. A burner system was designed and fabricated to efficiently elevate the emitter to a uniform temperature exceeding 2400°F, the required temperature to efficiently convert the radiant flux to electricity. The burner system generated a stable feed of vaporized fuel using a flow orifice. A short compact flame was produced with rapid heat release near the burner to achieve high energy efficiency and low emission of CO and soo'. Emitter temperature data for integrated systems under different operational conditions are presented.
