FIELD: heating.SUBSTANCE: invention relates to a fuel atomiser. Fuel atomiser is intended mainly for coaxial fuel spray into air flow (8), which annularly envelopes the fuel atomiser; it includes pipe (2) with outlet opening (10); besides, pipe (2) is connected to fuel supply main line for fuel supply to pipe (2). Fuel is sprayed from outlet opening (10) to air flow (8), and the first section (4) of the pipe, which reaches its outlet opening (10), is made in the form of petals (6); core (14) of petals, which is closed and has a conical shape, is located in outlet opening (10). Core (14) of petals is pointed in the stream direction. Core (14) of petals is made in the form of a double cone. Core (14) of petals includes notches (16) that are straight in the stream direction and/or curved. The first pipe section (4) converges in the stream direction. Core (14) of petals is connected to supply pipe (30) of high-calorific fuel, which passes coaxially to atomiser pipe (2), and has at least one tangential (16) and/or axial (17) inlet opening. At least one tangential inlet opening (16) is located on connection strap (19) of petals between two petals (18) of outlet opening (10).EFFECT: invention allows reducing formation of nitrogen oxides.10 cl, 8 dwg |
