COMBUSTION DEVICE, GAS TURBINE COMBUSTOR, AND COMBUSTION METHOD OF COMBUSTION DEVICE

摘要

PROBLEM TO BE SOLVED: To improve stability in combustion in a range of low fuel concentration, and to further reduce NOx of a discharged combustion gas. SOLUTION: A first plane including a jetting position of a plurality of spouts of a first burner and a second plane including a jetting position of a plurality of spouts of a second burner are intersected to allow the fuel flow from at least one first burner among the plurality of burners and the flame from the second burner are intersected with each other. Thus, the stability in combustion in the range of low fuel concentration can be improved, and NOx of the discharged gas can be further reduced. COPYRIGHT: (C)2007,JPO&INPIT
