BOILER WITH DOUBLE-CHAMBER SWIRLING-TYPE FURNACE Russian patent published in 2017 - IPC F23C3/00 

FIELD: heating system.

SUBSTANCE: boiler with a double-chamber swirling-type furnace contains two shielded swirling-type combustion chambers having lower fuel jet ejectors and secondary blast nozzles, oriented tangentially to the conventional rotary body of the formed vortex with an axis passing through the gas outlet windows with which they are connected to the afterburner chamber located between them. The gas outlet windows are made in the form of a protruding annular air duct with a nozzle for feeding a swirling stream of afterburning air blast installed on its end surface and directed into the combustion chamber. The swirling-type combustion chambers in section have the form of a polygon circumscribed around the conditional circle, and they are equipped with burners, ash-handling devices, as well as layer furnace devices with fuel supply systems and ash unloading units.

EFFECT: efficient combustion process without stagnant zones and stable operation of the boiler.
