REHEAT BURNER FOR GAS TURBINE AND GAS TURBINE CONTAINING SUCH REHEAT BURNER

摘要

FIELD: gas industry, electricity.;SUBSTANCE: present invention relates to a reheat burner for a gas turbine for power plants. In particular, the present invention relates to the shape of the rear edge of a reheat burner fuel injector for a gas turbine. In addition, this application relates to a gas turbine comprising a first burner, or a premix burner, and a second burner or reheat burner, equipped with the aforementioned fuel injector that are arranged in series along a main gas stream. The burner (22) for the gas turbine (1) comprises: a gas flow channel (25) having an axis (24) parallel to the direction (M) of the main gas flow; at least one fuel injector (26) comprising at least one streamlined body (28) extending straight across the gas flow channel (25) along a first transverse plane direction (29) perpendicular to the gas flow direction (M). And the streamlined body (28) contains a petal trailing edge (31) containing turning points (34) and petals directed alternately in the opposite direction along the second transverse direction (33) perpendicular to the first transverse direction (29) in a plane perpendicular to the direction (M) of the gas flow, and the petal trailing edge (31) is a trailing edge (31) with conical petals, containing a vertex section (35) essentially parallel to the first transverse direction (29), and two lateral sections (36), connecting the turning points (34) to the vertex section (35). ;EFFECT: invention is aimed at creating a gas turbine reheat burner.;14 cl, 17 dwg
