METHOD AND APPARATUS FOR ATOMIZING FUEL

摘要

In accordance with the present invention an improved liquid fuel atomizing gun and method is disclosed wherein optimal efficiency atomization is accomplished by introducing liquid fuel under pressure in a first swirling spiral direction into a mixing chamber. The mixing chamber also includes means for introducing steam through a plurality of inclined orifices to introduce the steam and impact the sprayed liquid fuel in a contra-rotational swirl direction. This arrangement of opposite swirling directions of the injected fuel and steam in the gun mixing chamber produces maximum turbulence between the two fluids as each impinge upon the other in relative close proximity so that the kinetic energy of each stream, both oil and steam, is released as the opposing streams meet. The impact of such opposed liquid fuel and steam streams produces higher Reynolds numbers which result in additional turbulence for enhanced mixing.
