I think the flame on a NS 330 is going to be higher than on a silver B.
The E330 main burners are rated at 12,667 BTU each
The length of the burner holes on a 330 burner is about 14.5 inches.
874 BTU per inch.
Silver B has 12,000 BTU burners
The length of the burner holes on a silver B is about 18.5 inches
650 BTU per inch
So the E330 burners put out 34% more BTUs per inch, which I think explains the taller flames.
