Abstract
An atomizer and atomizing process of a post-mixed liquid fuel fired burner comprising angular direction of atomizing fluid into liquid fuel as it passes along a fuel passage length of increasing surface area causing the formation of a fuel film on the fuel passage surface area with the increasing thinning of the fuel film as it passes across the increasing surface area, resulting in a shearing action at the fuel passage end and the formation of an atomized spray.
Claims17
An atomizer for a post-mixed burner comprising:
- (A) a liquid fuel passage having a first length of relatively small cross-section, a second length of increasing cross-section having a radially outward taper, and a third length of relatively large cross-section, said third length communicating with a furnace zone;
- and
- (B) at least one atomizing fluid passage having an injection end angularly communicating with said fuel passage so as to direct atomizing fluid onto said second length proximate the start of the outward taper.
A process for atomizing liquid fuel in a post-mixed burner comprising:
- (A) passing liquid fuel through a fuel passage having a first length of relatively small cross-section, a second length of increasing cross-section having a radially outward taper, and a third length of relatively large cross-section;
- (B) angularly directing atomizing fluid into physical contact with said flowing liquid fuel proximate the start of the outward taper and across said second length to form a thin fuel layer on the fuel passage wall;
- and
- (C) passing fuel and atomizing fluid out from said third length into a furnace zone as an atomized spray.
