摘要： A method and apparatus for providing air cooling to the venturi (11) and the combustion chamber (13) in a low NOx emission combustor (10) as used in a gas turbine engine that includes providing an annular air passage (14) surrounding the combustion chamber/venturi near the aft portion of the combustion chamber (13) passing the air along the combustion chamber (13), past the venturi (11) where the air exits (28) near the front portion of the convergent area of the venturi (11). The cooling air is heated as it passes over the combustion chamber (13) and the venturi (11) and then it is directed back into the premix chamber (12) thereby improving the efficiency of the combustor (10) while lowering the NOx emission in the combustion process.

摘要： A combustion liner (30) utilizes a plenum (31) for containing cooling air and for reintroducing it into the combustor (35). The plenum is enlarged to increase the amount of cooling air contained. To install the liner assembly into the combustor, recesses (32) into liner (30) allow the liner assembly (30) to slide underneath mounting pegs (19). Finally, the liner is rotated to abut the tabs (18) against the pegs (19).

摘要： A wear reduction means for a fuel nozzle interface of an industrial gas turbine combustor (10) is disclosed. The wear reduction means includes a replaceable insert (47) welded into to the engagement location (45) of the fuel nozzle tip (44). The fuel nozzle tip is coated (48) with a material harder than the replaceable insert, such that any wear due to mechanical contact of the mating components is directed to the replaceable insert.

摘要： An apparatus and method of providing a gas turbine combustor having increased combustion stability and reducing pressure drop across a gas turbine combustor is disclosed. A plurality of vanes is fixed to a flow sleeve radially between the flow sleeve and a combustion liner. The plurality of vanes serve to direct a flow of air entering the region between the flow sleeve and combustion liner in a substantially axial direction, such that components of tangential velocity are removed thereby providing a more uniform flow of air the combustion chamber and reducing the amount of pressure lost due attempting to straighten the airflow by pressure drop alone.

摘要： An improved gas turbine blade (40) is disclosed that utilizes a blade tip shroud (46) with tapered shroud pockets (52) to remove excess weight from the shroud (46) while not compromising shroud bending stresses. Excess shroud weight removed by the tapered pockets (52) reduces overall blade pull while maintaining material necessary to increase shroud stiffness. The resulting rib (53) created between the tapered pockets (52) provides a surface, away from possible areas of stress concentration, for drilling radial cooling holes (54).
