GAS TURBINE COMBUSTOR AND GAS TURBINE

摘要

In a gas turbine combustor and a gas turbine, a pilot burner, a plurality of main burners, and a pilot cone are provided, and an air passage that ejects air toward a tip end portion side outside the main burner, air passages that circulate the air toward a tip end portion side outside a pilot cone and ejects the air toward an outside in a radial direction, and an eaves portion (change member) that changes an ejecting direction of the air ejected through the air passages to a direction of a central axis center O of the pilot cone are provided.

主权项

1. A gas turbine combustor comprising:
a combustion chamber having a cylindrical shape; a pilot burner arranged in a central portion in the combustion chamber; a plurality of main burners arranged to surround the pilot burner in the combustion chamber; a flame stabilizer covering an outside of a pilot nozzle in the pilot burner and having a tapered cylinder shape where a tip end portion side radially expands; a first air ejection portion adapted to eject air toward a tip end portion side outside the main burners; a second air ejection portion adapted to circulate air toward a tip end portion side outside the flame stabilizer and eject air toward an outside in a radial direction; and a change member adapted to change an ejecting direction of the air ejected through the second air ejection portion to an axial center direction of the flame stabilizer.
