METHOD OF FUEL FIRING USING OXYGEN-CONTANING GAS, BURNER FOR INDEPENDENT INJECTION AND METHOD OF GLASS LOAD HEATING AND FURNACE HEATING Russian patent published in 2009 - IPC F23D14/22 

FIELD: heating.

SUBSTANCE: invention relates to powder engineering. The method of fuel firing with oxygen-containing gas wherein fuel jet is injected and, at least, two jets of oxygen containing gas that features high oxygen content. Note here that the 1^st jet of aforesaid gas, called a primary jet, is injected to allow its contact with the fuel jet and to form the 1^st incomplete firing. Note here that outlet gases, thereafter, contains, nevertheless, at least, one fraction of fuel. Note also that the 2^nd aforesaid jet is injected at the distance of l₁ from the fuel jet to allow firing together with the said 1sr fuel fraction existing in outlet gases after 1^st firing. Oxygen containing gas with low oxygen content is injected at the distance l₂ from the fuel jet providing the firing together with the said outlet gases after 1st firing, where l₂>l₁.

EFFECT: firing gas with low oxygen content.
