FIELD: heating systems. ^ SUBSTANCE: invention refers to power, transport and chemical engineering industries, and can be used at gas turbine plants. The specified effect is reached in the burner consisting of an external axially symmetric shell, an air swirler, located coaxially relative to this shell, with air-guide ducts and a sleeve forming together with the above external shell a circular pre-chamber, at the inlet whereof there is a fuel-distributing device made in the form of headers with holes intended for feeding fuel to pre-chamber by the fact that according to invention the air swirler is made in the form of a hollow cone, and air-guide ducts are made in the form of a circular row of tangential slots locates along generatrixes of that cone. At that fuel-distributing device is made in the form of headers which are parallel relative to the above slots, and the holes feeding fuel to pre-chamber are distributed throughout the length of headers. ^ EFFECT: improving environmental performance and operating reliability of gas-turbine plant. ^ 6 cl, 3 dwg |
