<P>PROBLEM TO BE SOLVED: To reduce an environmental load and suppress a pressure change by preventing flame from adhering to a burner, thus securing reliability for a combustor even if hydrogen-containing fuel is burned. <P>SOLUTION: The gas turbine combustor includes: a combustor chamber to which fuel and air are supplied to solve the problem; an air hole plate which is located on an upstream sidewall surface of the combustor chamber, and in which a plurality of air holes are formed in a concentric row shape; and a fuel nozzle which is arranged at the upstream side of each air hole of the air hole plate, wherein an air hole clearance which is formed between each air hole row on the surface of the side of the combustor chamber of the air hole plate protrudes toward the side of the combustor chamber. <P>COPYRIGHT: (C)2013,JPO&INPIT |
