ENERGY EFFICIENT MICROFLARE BURNER APPARATUS Russian patent published in 2021 - IPC F23D14/02 F23R3/42 

FIELD: energy.

SUBSTANCE: energy-efficient microflame burner device contains a combustion chamber consisting of a diffuser, converging and cylindrical sections, a swirling device, a cooling channel, a casing, and an igniter. It also contains a stage for supplying air from the cooling channel to the diffuser section of the combustion chamber, the said stage for supplying air is made up of holes in the wall of the diffuser section, made tangential to its surface, the combustion chamber is made counter-current, and the swirling device is multi-threaded. The burner device contains an inner guide casing and a system of tangential fuel distribution channels.

EFFECT: invention provides an increase in the radial and circumferential uniformity of the temperature field at the inlet to the emitter, an increase in the uniformity of the distribution of the excess air coefficient at the inlet to the diffuser section of the combustion chamber, a decrease in the probability of a flame front breakthrough into the region of gas-dynamic interaction of fuel and air jets entering the combustion chamber, an increase in the reliability of ignition of fuel and air mixture.
