Abstract
This invention pertains to an apparatus and means to lower emissions of carbon monoxide and nitrogen oxides in lean, pre-mixed gas turbine combustors. Specifically, this invention employs a catalyst deposited on the inner surfaces of the combustor in the region of combustion which oxidizes CO combustion products. Also provided is a means for depositing a catalyst within the thermal barrier coating on the combustor liner walls.
