LOW-PRESSURE CONTROLLED BURNER Russian patent published in 2008 - IPC F23D11/00 

FIELD: heat power engineering.

SUBSTANCE: burner comprises chamber for supply of air, swirling chamber, blade swirler of air flow with rotatable deflecting blades, Venturi nozzle formed by the diverging pipe, narrowed section, and diffuser, pipeline for supplying fuel mounted coaxially in the narrowed section with the spraying openings whose axes are perpendicular to the axis of the Venturi nozzle, combustion stabilizer, load controller, handle of load controller that is kinematically connected with the rotatable deflecting blades, and flow rate controller. The diffuser of the Venturi nozzle is made of the passage of the inlet unmovable male section, passage of the outlet female section mounted for permitting sliding, and movable section and is mounted for permitting the surface of the passage of the diffuser in all positions of its variable length to be smoothly diverging. The inlet unmovable section of the diffuser is in communication with the narrow section, and outlet movable section of the diffuser at the outlet end is in communication with the face wall of the combustion stabilizer and is provided with the rods for axial movement over the outer side of the inlet unmovable section of the diffuser.

EFFECT: expanded functional capabilities.
