BURNER UNIT Russian patent published in 2005 - IPC

FIELD: heat power engineering.

SUBSTANCE: invention can be used in furnaces of different application. In proposed burner unit containing base with fitted-on fan volute housing with motor, pipe and detachable replaceable gaseous or liquid fuel adjustable feed unit, reduction of labor input at adjusting and maintenance and repair operations is provided by installing swirler in tangential branch pipe, and also perforated shell and cover forming stationary fuel-air mixture combustion chamber in shell space communicating through holes in shell with circular clearance around chamber. In process of operation of device, part of air flow swirled by branch pipe gets to swirler and to chamber, thus providing high quality mixing of fuel with air and rendering steady shape to burner flame cone lobe extended along shell, and other part of flow passes along circular clearance and gets through holes in chamber, thus providing constant make up and maintaining stable characteristics on inner flow.

EFFECT: reduced labor input at adjusting and maintenance.
