FIELD: burning of gaseous fuel in furnaces of power generation boilers, combustion chambers of gas-turbine or vapor-gas plants and in industrial furnaces. ^ SUBSTANCE: burner includes gas adapter with gas supplying openings, chamber for preliminarily mixing fuel and air fed through air duct and at least two blade swirlers mounted at inlets of burning zone. Downstream part of chamber for preliminarily mixing is divided by means of partitions coaxially arranged in it at least by two compartments. Each compartment except central one has additional duct for supplying air. ^ EFFECT: simplified design and regulation of system for feeding fuel, enhanced efficiency of fuel combustion, desired ecological characteristics. ^ 3 dwg |
