FIELD: power industry. ^ SUBSTANCE: burner includes outlet opening with at least two sectors. At least one fuel atomiser corresponds to each sector; there are at least two separate fuel feed pipelines leading to fuel atomisers of various sectors, and there is control device of fuel mass flow flowing through the appropriate fuel feed pipeline. Adjustable valves located in the corresponding fuel feed pipeline are used as control device of fuel mass flow flowing through the corresponding fuel feed pipeline. Valves are adjusted separately so that in full load mode there provided is uniform fuel feed to all sectors so that homogeneous temperature distribution takes place. In partial load mode due to separate fuel feed control to separate sectors of the burner there can be created hotter and colder zones in combustion chamber; at that, hotter zones are created where maximum damping effects are expected. Besides, gas turbine equipped at least with one burner in compliance with the invention is described. ^ EFFECT: invention allows enlarging working range of burner and improving its adjustment possibility. ^ 16 cl, 6 dwg |
