Abstract

Atomizer (1) for a liquid fuel burner comprising a first mixer (8) for a fuel and an atomizing fluid which bears a central duct (9) for the fuel and a plurality of peripheral ducts (10) for the atomizing fluid which peripheral ducts (10) get to the central duct (9) obliquely or at right angle with respect to the central duct and comprising a second mixer (11) for the liquid fuel and the atomizing fluid already partly mixed one with the other which bears a mixing chamber (12) and a plurality of passages (14) for the delivery of the atomized fuel to a firebox.
