FIELD: power engineering.
SUBSTANCE: premixing combustion chamber in a gas turbine plant comprises a burner device with at least one guide vane for swirling a flow of a fuel-air mixture and a cylindrical output part, and also a flue tube with an input part in the form of a diffuser. The diffuser is arranged with solid corrugations arranged evenly along its circumference as longitudinal or diverging from a longitudinal direction by the angle 0°<α<90°.
EFFECT: invention increases completeness of fuel burning in a flue tube in a combustion chamber.
