Abstract
A combustor includes a pilot fuel nozzle and a plurality of main premixing nozzles arranged therearound for forming a premixture of air and fuel supplied from a main fuel nozzle, and is improved so as not to cause vibratory combustion. Pilot fuel nozzle unit,comprises a plurality of pilot fuel nozzles,A plurality of main premixing nozzles,are disposed on a coaxial circumference of the pilot fuel nozzle unit,The pilot fuel nozzles,are arranged irregularly in a circumferential direction of the pilot fuel nozzle unit,so as to form portion,where there is no pilot fuel nozzle,Premature in the main premixing nozzles,positioned corresponding to the pilot fuel nozzle,burns with comparatively short flames. Premature in the main premixing nozzles,positioned corresponding to the portion,of no pilot fuel nozzle,burns with long flames because of flames spreading from adjacent main fuel nozzles. Thus, by differences in flame length, heat generation rate distribution is dispersed.
