Researchers at Georgia Institute of Technology have developed a new type of combustion chamber for engine or gas turbines that burns with lower emissions than conventional engineering. Nitrogen oxides (NOx) and carbon monoxide emissions from this combustor are almost zero, according to Ben Zinn and colleagues. "We must burn fuel to power aircrafts and generate electricity for our homes. The combustion community is working very hard to find ways to burn the fuel completely and derive all of its energy while minimizing emissions," says Zinn. Called the Stagnation Point Reverse Flow Combustor, the Georgia Tech device, originally developed for NASA, significantly reduces NOx and CO emissions in a variety of aircraft engines and gas turbines that burn gaseous or liquid fuels. It burns fuel with NOx emissions below 1 parts per million (ppm) and CO emissions lower than 10 ppm, significantly lower than emissions produced by other combustors.
