A combustor effective for reducing exhaust emissions is disclosed. The combustor includes first and second liners defining a primary combustion zone, and a plurality of circumferentially spaced carburetors. Each of the carburetors includes a fuel injector providing fuel into an air swirler for mixing the air and fuel and providing a fuel/air mixture into the combustor primary zone. The combustor also includes means for obtaining a fuel distribution from each of the carburetors extending radially from a first liner upstream end through a center region of the combustor to a second liner upstream end with values of the fuel distribution at the center region being generally no greater than about values of the fuel distribution adjacent to at least one of the first and second liners. The first and second liners have upstream portions characterized by the absence of film cooling thereof.
