FIELD: burning fuel in combustion chambers. SUBSTANCE: method consists in oxidation of fuel with air preheated in presence of waste gases at definite ratio by mass of flows returned to cycle of waste gases and air for burning fuel and gas-air mixture is kept to temperature above ignition point; then gas-air mixture is mixed with fuel forming oxidation zone in combustion chamber where practically flameless and pulseless oxidation takes place. Device for burning fuel in combustion chamber is provided with system of nozzles for preheating the air which are located in form of rim around the fuel supply nozzle for suction of waste gases by injection effect again in fuel supply zone after burning of fuel. EFFECT: reduced amount of nitric oxides released in burning the fuel. 29 cl, 10 dwg
