Patent ID: 8037688

Claim:
A method for controlling temperature distributions within a combustor comprising, the combustor having a plurality of circumferentially positioned chamber sections therein, controlling fuel-to-air ratios in fuel flows and air flows supplied to each of the chamber sections, the plurality of chamber sections having among them a sequence of chamber sections successively positioned in the combustor with an end chamber section at each end of the sequence, the end chamber sections having fuel-to-air ratios that are larger than the fuel-to-air ratios of two further chamber sections, wherein each of the two further chamber sections are supplied with fuel and air and are positioned in the combustor adjacent to a corresponding one of the two opposite end chamber sections in the sequence of successively positioned chamber sections; and wherein the two further chamber sections have at least one additional chamber section from the plurality of chamber sections positioned between them in the combustor, the additional chamber section having a fuel-to-air ratio that is larger than the fuel-to-air ratio of the two further chamber sections.
