In most cases a VCO nozzle has a greater ignition delay than a micro-blind sac type nozzle. The VCO nozzle often has a cooler flame, greater duration, and greater intensity, whereas the micro-blind nozzle often has a hotter flame, slightly less duration, and less intensity. Flame intensity can also be parlayed into meaning basically the length of the jet, and the ability to penetrate the air density in the combustion chamber.
