BURNER APPARATUS Russian patent published in 2021 - IPC F23D14/02 

FIELD: power engineering.

SUBSTANCE: burner apparatus is comprised of a body open from above, wherein a toroidal collector is installed perpendicular to the axis thereof with an open radial gap, configured to be connected to a gaseous fuel supply system. K (K≥3) fuel mixing columns are installed on the collector coaxially to the body in the direction of burning. Each of the columns is comprised of a nozzle, the inlet part whereof is installed tightly on the fuel collector, and a mixer connected with the outlet part of the nozzle. Said columns are therein single-channel, each of the channels is narrowed at the outlet part of the nozzle, and in each cylindrical mixer at least two groups of radial holes are made at different levels with a possibility of adjusting the sizes of at least one of the groups by means of a shutter installed movably on the mixer. Radial holes are used to supply primary air to the outlet of the channel by the diffusion-injection method. Said collector is installed on supports, and at least two gas equalising holes are made in the body for supplying air to the burning area. The burner apparatus can also have a second circuit configured to be connected either to said fuel supply system or to an additional one.

EFFECT: invention allows ensuring stable burning, effective combustion of gaseous fuel of various composition.
