CF6-80C has 30 nozzles, some provide bigger flow for flameout protection, other operate when ignition is on. CF6-50 also 30 nozzles, some dual flow, others secondary flow only.
Compared to PW2000 (24 nozzles) and RB211 (15 nozzles), this is a high number indeed, I don't know why, but I suspect it's only a matter of manufacturer philosophy.
