Abstract
1. Горелка с центральной компоновкой (27) подачи топлива, а также с охватывающим центральную компоновку (27) подачи топлива кольцевым воздушным каналом (17) для подачи топочного воздуха и с расположенными в кольцевом воздушном канале (17) вихревыми лопатками (19), имеющими первые топливные форсунки (21) для впрыскивания, по существу, газообразного топлива в топочный воздух и вторые топливные форсунки (23) для впрыскивания, по существу, газообразного топлива в топочный воздух, причем первые топливные форсунки (21) питаются от топливораспределительного подвода в компоновке (27) подачи топлива, а вторые топливные форсунки (23) - от газораспределительного канала (31) в компоновке (27) подачи топлива, причем горелка при эксплуатации имеет одно направление потока топлива, отличающаяся тем, что топливораспределительный подвод содержит множество подающих труб (55), причем каждая подающая труба (55) соединена вниз по потоку с первыми топливными форсунками (21) соответствующей вихревой лопатки, а вверх по потоку - с кольцевой насадкой (60), и причем кольцевая насадка (60) предвключена, если смотреть в направлении потока, к топливораспределительному каналу (31) и насажена на компоновку (27) подачи топлива так, что пространственное разъединение между кольцевой насадкой (60) и топливораспределительным каналом (31) приводит к более низким напряжениям в компоновке (27) подачи топлива.2. Горелка по п.1, отличающаяся тем, что кольцевая насадка (60) содержит отдельное трубное соединение (75).3. Горелка по п.1 или 2, отличающаяся тем, что первый впрыск (21) топлива через форсунки питается от первой распределительной трубы (65), а второй впрыск (23) топлива через форсунки - от1. A burner with a central arrangement (27) of fuel supply, as well as an annular air channel (17) for supplying flue air and surrounding vortex vanes (19) located in the annular air channel (17), having a central arrangement (27) of fuel supply, having first fuel nozzles (21) for injecting substantially gaseous fuel into the combustion air and second fuel nozzles (23) for injecting substantially gaseous fuel into the combustion air, wherein the first fuel nozzles (21) are powered by a fuel distribution the supply in the layout (27) of the fuel supply, and the second fuel nozzles (23) from the gas distribution channel (31) in the layout (27) of the fuel supply, and the burner during operation has one direction of fuel flow, characterized in that the fuel distribution supply contains many pipes (55), with each supply pipe (55) connected downstream with the first fuel nozzles (21) of the corresponding vortex blade, and upstream with an annular nozzle (60), and moreover, the annular nozzle (60) is switched on if you look in the direction flow, to the fuel distribution channel (31) and mounted on the layout (27) of the fuel supply so that the spatial separation between the annular nozzle (60) and the fuel distribution channel (31) leads to lower voltages in the layout (27) of the fuel supply. 2. A burner according to claim 1, characterized in that the annular nozzle (60) contains a separate pipe connection (75). The burner according to claim 1 or 2, characterized in that the first injection (21) of fuel through the nozzles is fed from the first distribution pipe (65), and the second injection (23) of fuel through the nozzles from
