 The steam-assisted
pressure jet burners atomizer is designed to make full use of pressure jet
atomization at high outputs and full use of blast atomization at low
outputs.
The atomizer consists of a conventional simplex type of pressure jet tip,
around which is provided steam supply passage. Steam issues through an annular
gap after being provided with the correct degree of swirl to ensure that the
steam-exit angle matches the oil-spray cone angle. The steam-supply pressure
remains constant throughout the complete turndown range of the burner. No
mixing of fuel oil and steam occurs within the burner-gun and hence oil output
is unaffected by slight variations in the steam pressure.
