PROBLEM TO BE SOLVED: To improve a temperature profile of gas at an outlet of a combustion chamber and reduce hot spots which are harmful to the durability of components in this zone, especially a high pressure guide vane element. SOLUTION: This invention relates to an annular combustion chamber for a gas turbine engine comprising a casing (16) with at least one air output port (20) positioned at a combustion chamber inlet (11), and a fuel supply device with a plurality of fuel injectors (15) in the combustion chamber distributed annularly of which at least one (15a-15d) is positioned close to the output port. The combustion chamber has the fuel supply device provided with a means for reducing fuel flow rate of the fuel injectors (15a-15d) positioned close to the output ports (20a, 20b) as compared to other fuel injectors (15). The hot spots downstream of the combustion chamber caused by output are reduced by this invention. COPYRIGHT: (C)2009,JPO&INPIT |
