Abstract

The process obtains a plurality of small flames which become violet when combusting natural gas. In particular the amount of primary air induced is at least 80 % of the air stoichiometrically required for combustion; the secondary air laps all sides of each single small flame (F) arising from each small group (5) of slots (7, 7') on the burner body (1), in the area where each flame leaves the surface of the burner body (1) so as to swell it making its width at least as big as its height and/or alternatively the contact surface between each flame and the secondary air is increased right from the first steps in combustion, so that each small group (5) creates a small flame with two divergent bladed wings, similar to ''butterfly wings''.
