COOLING STRUCTURE AND COMBUSTOR USING THE SAME

摘要

PROBLEM TO BE SOLVED: To secure an excellent film cooling performance of a cooling structure by improving the adhesion of cooling air to the inner surface of a combustion chamber. SOLUTION: The combustor has grooves 34, cooling channels, communicating with cooling air intake ports 35 and cooling air outlet ports 36 for convection cooling as the cooling air taken from the cooling air intake ports 35 flows toward the cooling air outlet ports 36. The grooves 34 are slanted in the swirling direction of the combustion gas swirling inside to make cooling air intake channels for letting the cooling air flowing out of the cooling air outlet pots 36 flow out in the swirling direction of the combustion gas.
