FIELD: power engineering.SUBSTANCE: continuous combustion chamber comprises a cylindrical body with a cone-shaped diffuser at the inlet, a device for ignition of fuel and air mixture on the chamber wall and a burner joined coaxially to the diffuser. The burner includes systems to supply liquid and gaseous fuels each comprising auxiliary and main circuits, equipped with headers of fuel supply at the inlet and nozzles at the outlet. The gaseous fuel header communicates with nozzles via channels in mixing tubes. The burner additionally comprises a mixing chamber with a device of impact at the fuel-air mixture made in the form of a mixer with longitudinal corrugated folds of ? - shaped profile, arranged along the circumference of the flame stabiliser in groups.EFFECT: invention makes it possible to reduce level of smoking and emission of hazardous substances in fuel combustion products, to eliminate overheating of local zones in a flame tube and to implement stable process of fuel-air mixture burning process with suppression of vibration burning modes.7 cl, 6 dwg |
