<P>PROBLEM TO BE SOLVED: To provide a gas turbine combustor of high reliability that prevents flame from approaching an air-hole plate forming air-holes, achieves low Nox combustion and stably combusts a quickably-combustible fuel. <P>SOLUTION: In the gas turbine combustor, the air-hole plate configuring a combustion burner includes a conical protrusion in a combustion chamber side. The air-hole plate including the conical protrusion concentrically disposes a plurality of lines of the air-holes configured by the air-holes that are circumferentially provided from a center axis of the conical protrusion to a radial outer circumference. A flat surface part on which the conical air-holes are disposed outside the conical protrusion of the air-holes plate. At least one or more fuel nozzles are disposed so that ends of the nozzles are disposed to be located near an outlet of the air-holes formed on the air-holes plate in the lines of the concentrical lines disposed on the flat surface outside the conical protrusion of the air-holes plate. <P>COPYRIGHT: (C)2012,JPO&INPIT |
