  • Gas turbine combustor transition duct forced convection cooling
    Patent number: 4903477
    Abstract: In a gas turbine the transition duct is subject to high temperature since it conducts the combustion products to the power turbine. It is normally cooled by air from the compressor. This invention improves the uniformity of cooling by forcing the cooling air to pass over all surfaces of the transition duct. Air flow passages are formed between the ducts and saddle shaped members which direct the flow of air from the compressor over the outer surfaces of the ducts.
