초록 ▼

A fuel being primarily a liquid fuel is ejected through a fuel ejection pipe having an annular ejection opening; primary air is ejected through primary air-ejecting openings arranged on outer and inner sides of the fuel ejection opening, to form outer and inner primary air-ejection straight stream openings between which the fuel ejection stream is interposed, and to burn the fuel ejection stream. The fuel-spraying openings are arranged on the same circumference. The outer and inner primary air-ejecting openings, respectively, are each arranged on a respective concentric circumference having a center point identical to the center of the circumference on which the fuel-spraying openings are arranged. When a power fuel is used, optionally a liquid fuel is further ejected and mixed with the primary air stream, and the liquid and power fuels are burnt together.

1. An apparatus for burning a liquid fuel said apparatus comprising:a fuel-ejection means comprising a plurality of liquid fuel-spraying pipes (25a) each having a liquid fuel-spraying opening (26a) for radially spraying fuel in a fuel-election direction, each of plurality of liquid fuel-spraying opening (26a) being positioned on a first circumference having a center point (31); an outer primary air-ejection pipe (23) positioned outside and about the first circumference and having a plurality of outer primary air-ejection openings (24) therein through which primary air is ejected in parallel to the fuel-ejection direction from the liquid fuel-spraying openings (26a), wherein the air-ejection openings (24) are positioned on a second circumference positioned to extend about the first circumference; and an inner primary air-ejection pipe (27) positioned inside the first circumference and having a least one inner primary air-ejection opening (28) through which primary air is ejected in parallel to the fuel-ejection direction from the liquid fuel-spraying openings (26a), wherein the at least one inner primary air-ejection opening (28) is positioned on a third circumference extending within the first circumference; wherein the second and third circumferences are positioned concentrically with the first circumference with each having a center point being the center point (31) of the first circumference on which the plurality of liquid fuel-spraying openings (26a) are positioned.
