BURNER, TURBINE ENGINE AND FURNACE WITH SUCH BURNER Russian patent published in 2011 - IPC F23D14/02 F23C7/00 F23R3/14 

FIELD: power industry.

SUBSTANCE: burner, namely burner of gas turbine includes the following: at least one swirler (2); at that, swirler (2) has at least one air inlet hole, at least one air outlet hole located downstream of air inlet hole, swirl blades (12), support (13) of swirler, at least one air passage (14) of swirler, which passes between adjacent swirl blades (12) at least from one air inlet hole (16) at least to one air outlet hole (18) that is restricted with walls (20, 22) of air pass of swirler; at that, walls (20, 22) of air passage contain downstream sections of walls, which are adjacent to at least one air outlet hole, where at least downstream section is corrugated; and fuel spray system that contains the first fuel spray holes (26) located at least in one swirl blade (12) for fuel spray to air passage (14) of swirler, and the second fuel spray holes (28) that are located in swirler support (13); and at that, at least one first fuel spray hole (26) and at least one second fuel spray hole (28) are located near air inlet hole (16). Opposite walls (20, 22) of swirler air passage have corrugated profiles which complement each other. At least one first fuel spray hole (26) is located at least in upstream part of swirl blade (12), which adjoins the air inlet hole. Swirler support (13) has circular shape, and at least one first fuel spray hole (26) of swirler air passage (14) is located on certain radius of circular support (13) of swirler, and in which at least one second fuel spray hole (28) in swirler air passage (14) is located at least almost on the same radius as the first fuel spray hole (26). Swirler support (13) has circular shape, and at least one first fuel spray hole (26) of swirler air passage (14) is located on certain radius of circular support (13) of swirler, and in which at least one second fuel spray hole (28) in swirler air passage (14) is located at least almost on the same radius as the first fuel spray hole (26).

EFFECT: invention provides the possibility of fine adjustment of fuel and air mixing for obtaining homogeneous fuel-air mixture.
