FIELD: power engineering.SUBSTANCE: device for fuel burning includes central and peripheral air channels with swirlers arranged in a cylindrical body, the main and additional headers, rotary gas-dispensing tubes, installed on a circumference between air channels. Outlet holes of some tubes are arranged tangentially, and of the other ones - radially to the axis of the device, along the device axis there is additionally a central channel of gas supply installed, at the same time the ratio of the area of outlet holes of the central channel of gas supply to the total area of gas outlet holes of rotary gas dispensing tubes and central channel of gas supplymakes 0.1-0.4. Gas-dispensing tubes are connected with the main header, and the central channel of gas supply - with an additional header.EFFECT: invention makes it possible to reduce content of nitrogen oxides in combustion products and provide for stable operation of a device in a range of control of thermal capacity of a device and safe mode of equipment operation in general.2 dwg |
