and lightly dusty streams. The highly concentrated flow enters the burners 2, the torches of which form a common vortex torch, in which, due to the high turbulence of the gas, all the gas is large. fuel and the absence of bapasta in the form of a weakb611®Lenno g6 p6t of an eye, besides it is effective with combustion. . (); a weakly eeral flux enters through the discharge nozzles 3 into the axial region of chamber 1, into which, under the influence of the vortex plume, a region of reduced pressure is formed, which allows for leakage from laboratories and reduction of resistance. Besides, the supply of lightly dusty flow along the axis. chambers 1 provides a hot spot for the use of o1e1i1kamer1ry I, efficient combustion of the fuel contained in a slightly dusty stream, leveling of temperature and velocity unevenness of irregularities. 1Aber 8 produces a low flow rate controlled flow, which passes through the discharge nozzles 3, which allows the process of fuel combustion to be conducted in the optimum mode both according to the conditions of combustion efficiency and

and according to the conditions for reducing the formation of nitrogen oxides in flue gases.
