TUBULAR-ANNULAR COMBUSTION CHAMBER OF GAS TURBINE Russian patent published in 2000 - IPC

FIELD: gas turbines. SUBSTANCE: combustion chamber mainly burning compressed natural gas emitting low-toxicity exhaust gases has flame tubes connected to gas collector which is fixed to external and internal casings and has its inner space formed by its own annular walls. Each flame tube has front wall at outlet in crosswise direction to flow which is attached to flame tube wall and connected to gas collector. A number of holes are provided in each flame tube upstream of front wall and audio oscillators designed for augmenting mixing processes and improving completeness of fuel combustion are placed at distance not longer than mentioned hole diameter from them; flame-tube wall is solid structure past mentioned audio oscillators. Each oscillator is inserted in pipe connection attached to flame tube wall; center line of pipe connection lies in radial plane of flame tube crossing corner of front wall. EFFECT: reduced toxicity of exhaust gases; reduced fuel consumption. 3 dwg
