FLAME TUBE

摘要

PURPOSE: A flame tube for a combustion chamber of a gas turbine or a liner is provided to reduce the emission of pollutants, to secure high combustion efficiency, and to expand the life span of components exposed to high temperature. CONSTITUTION: A flame tube(112) or a liner for a combustion chamber(110) of a gas turbine having low emission of pollutants is composed of a cylindrical structural body connected to an outlet of a premixing chamber(114) through a truncated conical end part(120). The premixing chamber receives air guided by a cavity(116) positioned between the flame tube and an outer wall(118) of the combustion chamber and the air circulates in the direction opposite to the flow of combustion products. A first cylindrical area(122) of the flame tube is surrounded by a cylindrical casing(136) forming an annular chamber.
