Abstract
A flame tube having a tubular body with an inner side surface, extending around an axis (A), an inlet section and an outlet section, a plurality of fins leaning out, substantially in the radial direction (R), from the inner side surface towards the axis (A) is provided. The fins have an extended surface whose tangent (T), in a point (C) normal to the radial direction (R), is skew with respect to the axis (A), a first and a second fin forming an interspace between the respective extended surfaces facing one another and whose ideal extension (P) in the direction of the tangent (T) encounters a third fin.
