TWO-STAGE VACUUM BURNER Russian patent published in 2018 - IPC F23C6/04 F23D17/00 

FIELD: power industry.

SUBSTANCE: three-vortex vacuum burner-reactor (100) for mixed fuels contains an intake manifold (150) which includes a vacuum chamber, a nozzle inlet for compressed air into a vacuum chamber, a nozzle for compressed air entering the vacuum chamber through the nozzle inlet for compressed air, and an ejector release, at that, the intake manifold (150) is configured with the possibility of feeding gaseous fuels to primary combustion chamber (110), the primary combustion chamber (110) which has with a cylindrical external part and a conical inner part. The conical inner part has a first end with a smaller diameter and a second end with a larger diameter. The first end of the conical inner part is connected to the inlet manifold (150). Conical inner part additionally includes the first group of directing blades; a reducing nozzle (120) connected with the second end of the conical internal part of the primary combustion chamber (110). The reducing nozzle (120) has the first part in the form of a truncated cone with a larger diameter, connected with the primary combustion chamber (110), and a second cylindrical part which continues from the first part of a smaller diameter in the form of a truncated cone; injectors (140) perpendicular to the first part in the form of a truncated cone of the reducing nozzle (120) and configured with the possibility of fuel injection into the primary combustion chamber (110); and a cylindrical secondary chamber (130), having a second set of directing blades configured with the possibility of channelling air into the secondary chamber (130). The smaller the diameter of the primary combustion chamber (110) at its first end, the larger diameter of the primary combustion chamber (110) at its second end and the first group of three directing blades form three vortexes of fuel to maintain fuel rotation to the outer part of the burner-reactor (100) and slowing down the movement of fuels to ensure complete combustion.

EFFECT: invention makes it possible to improve the quality of fuel combustion.
