Combustion apparatus and combustion method therein.

摘要

A combustion apparatus comprises a combustor liner (3) forming a combustion chamber, and a swirler for introducing a fuel gas into the combustion chamber in the form of a swirl. The combustor liner (3) has an air film forming means (5a,6,6b) provided on the wall thereof and capable of forming a film of cooling air on the inner peripheral wall of the combustor liner so as to protect the combustor liner from the hot combustion gas in the combustion chamber. The air film forming means (5a,6,6b) is such that the flowing direction (CAR) of the air forming the film becomes the same direction as the swirling direction (BF) of the combustion gas, so that the film of the cooling air is not broken by the hot combustion gas.
