METHOD TO REGULATE PARAMETERS OF GASEOUS FUEL COMBUSTION Russian patent published in 2014 - IPC F23D14/60 

FIELD: power engineering.

SUBSTANCE: method to regulate parameters of a burning flare with the help of a double-wire burner, in the central and circular channels of which, equipped with coaxial nozzles, they simultaneously supply gaseous fuel, the ratio of output areas of the central and circular nozzles is maintained within the limits of 1.5…2.5, at least half of the total fuel flow is supplied via the circular nozzle, and the angle of burner inclination along the vertical line down from the longitudinal axis of the furnace is changed within 2 - 12° as fuel flow rises via a central nozzle. Fuel flight out along the circumference of the circular nozzle is done in separate jets that alternate with sections closed for fuel exit.

EFFECT: expanded range of regulating dimensions, shape and position of flare in the working space of the furnace, providing for complete burning of gaseous fuel and efficiency of heat recovery.
