Combustion chamber of a turbine engine equipped with an anti-coking device for the bottom of said chamber

摘要

The invention relates to a combustion chamber of a turbine engine comprising a bottom comprising a flared wall (7), a fuel injection assembly (13-15) mounted on said bottom, a device (21) for primary admission of oxidant to the interior of the combustion chamber, a tubular pipe (9) arranged between the flared wall (7) and the injection assembly (13-15) and delimiting an auxiliary chamber (26) containing the injection assembly (13-15) and opening into the combustion chamber (8), and an auxiliary set of orifices (27) for admission of oxidant into the interior of the auxiliary chamber. According to the invention, the auxiliary set of orifices for admission of oxidant comprises a plurality of orifices (27) which pass through the wall of said tubular pipe (9). One application is making a simple, light and efficient combustion chamber. <IMAGE>
