My primary research is catalytic combustion. The photo shows a pair of catalytic combustors for a gas turbine. The metal foil is coated with catalyst on just one side so that when the foil is folded back and forth upon itself, catalyzed channels alternate with uncatalyzed channels. Only the fuel which goes through the catalyzed is burned in the combustor.
Catalytic combustion is completed downstream of the combustor.
The window of time and temperature that makes thermal NOx is avoided so that NOx production is reduced. If you have any questions about these catalytic combustors, or about this catalytic combustion process, please contact me .
