GAS TURBINE CANNULAR-TYPE COMBUSTION CHAMBER Russian patent published in 1999 - IPC

FIELD: gas turbine combustion chambers. SUBSTANCE: gas turbine cannular combustion chamber works on compressed natural gas at low toxicity of exhaust gases; it includes flame tubes connected with gas receiver and fastened with external and internal cases whose cavity is formed by its own circular walls. Each flame tube has front wall at outlet in direction opposite to flow which is fastened with wall of flame tube and connected with gas receiver. Acoustic oscillators are arranged in external and internal cases above front wall in way of flow. Each flame tube has row of holes after which wall of flame tube is continuous. Acoustic oscillators in external and internal cases and holes in each flame tube are located in one plane which is parallel to plane of front wall. EFFECT: reduced toxicity of exhaust gases; increased fuel saving due to intensification of mixing process by acoustic oscillators; increased completeness of combustion of fuel. 2 dwg
