CS266233B1 - Burning fuel and torch therefor - Google Patents

Abstract

The solution belongs to thermal engineering and can be used in the combustion of gaseous fuel in the flame-off mode, especially in low-temperature devices. The solution consists in the fact that a secondary gas with an oxygen content is additionally introduced into the space of the toroidal burner opening, in which the oxygen content constitutes 1.0 to 25% of the amount of oxygen in the primary gas B with an oxygen content. In this case, the central tube is led out beyond the nozzle at a distance constituting 0.2 to 2.5 diameters of the outlet cut of the casing.

Claims (2)

266233 OBJECT OF THE INVENTION 1, a method of combusting a fuel by supplying a space of a toroidal burner opening with an annularly rotated primary gas stream comprising oxygen and a central fuel stream, with simultaneous entry along an axis of a secondary oxygen-containing gas, characterized in that, in order to ensure stable operation in the off-flame mode, the oxygen content of the secondary gas containing oxygen is 1.0 to 25 # of the amount of oxygen in the primary oxygen-containing gas 2. A burner for carrying out the method according to claim 1, comprising a casing, adhering to the toroidal burner aperture and provided with a vortex where a gas nozzle is provided with a supply air pipe extending through the front end of the gas nozzle; and, because of the aim of providing stable operation in the flame off mode, the central pipe is led beyond the nozzle boundary to a distance of 0.2-2.5 diameter of the bushing exit cut.
