BURNER SYSTEM Russian patent published in 2018 - IPC F23R3/14 F23D3/34 

FIELD: power engineering.

SUBSTANCE: invention relates to the power engineering. Burner system for a combustion chamber, in particular a gas turbine combustion chamber, for burning liquid combustible materials, with a main burner and with a pilot burner centrally located in it, which is designed to ignite and/or stabilize combustion of the main burner; main burner includes a first annular air passage for supplying combustion air and first fuel injectors for injecting combustible material into the first annular air passage, pilot burner includes a second annular air passage for supplying combustion air and a burner head with second fuel injectors for injecting combustible material into the second annular air passage, and the second fuel injectors are configured in the form of separate controllable first and second stages of supplying combustible material. In order to supply combustible material to the first and second stages of supplying combustible material, a burner supporting tube connected to the burner head with a tube wall is provided, wherein the tube wall, which is parallel to the longitudinal axis of the burner supporting tube, has at least one first and one second deep holes for supplying combustible material with the first and second stages of supplying combustible material.

EFFECT: invention allows to reduce emission of harmful substances, ensure the simplicity and economy of manufacturing.
