COMBUSTION CHAMBER OF GAS-TURBINE PLANT Russian patent published in 2001 - IPC

FIELD: mechanical engineering. SUBSTANCE: combustion chamber operates primary on compressed natural gas at low toxicity of exhaust gases, mainly, Nox and Co. Combustion chamber has a number of tubular jackets positioned inside body and attached to it. Every jacket accommodates flame tube coupled to burners and to gas collector and provided with front device. Each of flame tubes is secured to input part of jacket at inlet by means of lateral wall with a number of holes which form circular cavity together with inlet end of gas collector. Jacket is made in the form of diffuser in direction of place of its attachment to body, and it divides combustion chamber space into parts. One of parts equals burning cavity of flame tube coupled to gas collector, and other part exceeds burning cavity space by whole number of times. Combustion chamber also includes air ducts and regulators of air by-pass from chamber cavity to gas collector arranged on the outside of body. Inlet of air ducts is located downstream from joint of jacket with gas collector and its outlet is coupled to gas collector through walls of body. Axes of burners are positioned at an acute angle to flame tube wall. They cross with each other and with flame tube axis. EFFECT: reduced toxicity of exhaust gases and fuel gas consumption. 2 cl, 2 dwg
