Gas turbine combustion chamber - has concentric settling piece between combustion chamber outlet and turbine inlet cone

摘要

A gas turbine has a combustion chamber (8) between the last blade row of the compressor and the first blade row (2) of the turbine wheel. The air enters the combustion chamber through openings (6) in its side from an annular space downstream of the compressor. There is a converging inlet cone (3) on the inlet of the turbine between the combustion chamber and the turbine. This evens out velocity fluctuations in the gas coming from the combustion chamber. An additional settling piece (9) is inserted between the outlet of the combustion chamber and the entry of the inlet cone (3). Temperature fluctuations in the gases are eliminated in this and thus velocity changes due to temperature fluctuations are also eliminated.
