BURNER FOR GASEOUS FUEL WITH HIGH ENERGY SAVING AND COMBUSTION EFFICIENCY WITH LOW EMISSION OF POLLUTANTS AND HIGH HEAT TRANSFER Russian patent published in 2016 - IPC F23D14/02 F23D14/62 

FIELD: energy.

SUBSTANCE: invention relates to power engineering. Invention relates to design of burner for gaseous fuel (including all its mixtures) including a casing, which determines the distal end for output of flame and a proximal edge for supply of gaseous fuel and air; both edges have gate. Air intake for compressed air is located on the casing near the proximal edge and determines the inner chamber to feed compressed air. Tube for supply of compressed gaseous fuel is located at the center inside the first mixing chamber and has multiple holes for discharge of gaseous fuel in said first mixing chamber, in which also there are multiple holes for supply of compressed air radially. Igniter is arranged inside said first mixing chamber for the first and second combustion chamber for additional mixing is collinearly with respect to said first chamber. End of said fuel tube has a lock with axial holes, through which gaseous fuel is supplied to the said second chamber for additional mixing, its wall has holes, through which compressed air is fed radially such that the second stage of combustion process is provided. Third cone-shaped fire chamber is installed collinearly and is connected to the end of the said second chamber for additional mixing.

EFFECT: higher quality of mixing of fuel and oxidizer, reduced emission of hazardous substances into atmosphere.
