Abstract

The improved atomizer comprises a first (8) and a second (11) mixer for a fuel delivered through a central inlet means (3) and for an atomizing fluid delivered through a peripheral inlet means (4), the first mixer (8) including a first mixing chamber (9) whereto the fuel arrives from the central inlet means (3) and the atomizing fluid arrives from peripheral ducts (10), the second mixer (11) including a second mixing chamber (12) for the fuel and the atomizing fluid that complete their mixing therein and a plurality of outlet means (14) for the delivery of the completely atomized fuel to a firebox, the relations among the length, diameter and cross-sectional area of certain parts which cooperate in the atomizer being defined to impart an effective atomization to the fuel and supply an advantageous pencil of atomized fuel into a fire-box.
