Abstract
A pilotless catalytic combustor () including a basket () having a central axis () and a central core region () disposed along a portion of the central axis. Catalytic combustion modules () are circumferentially disposed about the central axis radially outward of the central core region for receiving a fuel flow () and a first portion of an oxidizer flow (), and discharge a partially oxidized fuel/oxidizer mixture () at respective exit ends (). A base plate () is positioned in the central core region upstream of the exit ends of the catalytic combustion modules, the baseplate defining a recirculation zone () near the respective exit ends for stabilizing oxidation in the burnout zone. A method of staged fueling for a pilotless catalytic combustor includes providing fuel to at least one of the modules during start up and progressively providing fuel to other modules as a load on the turbine engine is increased.
