FIELD: preliminarily mixing of fuel and air for combustion chambers of gas-turbine plants. SUBSTANCE: fuel distributing channels in fuel nozzle are oriented and positioned relative to rear end of adjacent cylindrical section so that, with nozzle operating in nonstandard mode, fuel flowing out of them does not promote maintenance of burning inside combustion chamber upon expiration of limited period when fuel-to-air relations are below definite threshold value. Invention makes it possible to prevent occurrence of flame inside mixing chamber of nozzle and to reduce ejection of contaminants into atmosphere. EFFECT: simplified construction. 13 cl, 4 dwg
