BURNER AND METHOD FOR ALTERNATE REALISATION OF OXYGEN BURNING AND AIR BURNING Russian patent published in 2011 - IPC F23C9/00 F23D14/32 F23D14/24 F23L7/00 

FIELD: power engineering.

SUBSTANCE: method to burn at least one fuel with application of at least one oxidiser and at least one mainly inert gas, in which the fuel and the oxidiser are injected so that flame is developed, mainly the inert gas is injected in the form of two jets so that the first jet surrounds the flame developed by the fuel and the oxidiser, and the specified first jet has an opening twist in respect of the specified flame, the second jet surrounds the first jet of the mainly inert gas, and the specified second jet has a closing twist in respect of the flame developed by the fuel and oxidiser. The oxidiser is an oxygen-containing gas, and the mainly inert has consists of gases produced by burning. Consumption of the mainly inert has injected in the first jet of the mainly inert has makes from 50 to 97% of the total consumption of the injected mainly inert gas. Consumption of air supplied as the oxidiser makes from 5 to 30% of the total consumption of air required to burn the fuel. The coefficient of each jet twisting of the mainly inert gas is between 0.26 and 1.73.

EFFECT: invention makes it possible to reduce content of CO₂ and NO_x in combustion products.
