Abstract

Turbo machine combustion assembly (1) comprising a combustion chamber (10), at least one starting injector (17), a plurality of main injectors (18) distributed at constant angular intervals around the circumference of the combustion chamber, each starting injector being positioned between two consecutive main injectors, equal distances therefrom, and a fuel supply circuit (40) supplying fuel to the injectors, in which assembly the combustion chamber is delimited by two axisymmetric walls - an external wall (14) and an internal wall (12) - which are connected by an annular chamber end wall (16), the fuel supply circuit being designed to supply at least one starting injector continuously, each continuously-supplied starting injector being oriented toward the chamber end wall and dimensioned to spread a spray (F) of fuel between 120° and 180° wide, and the flow rate of fuel injected by the main injectors (18') between which the starting injectors are positioned being reduced by comparison with the flow rate injected by the other main injectors (18).

Description

Technical field [0001] The present invention relates to the field of turbines, and more particularly, to the field of turbine combustion assemblies, which include a combustion chamber and a plurality of injectors dedicated to starting and supplying fuel to the combustion chamber. Background technique [0002] Reference figure 1 The turbine 1 generally includes a combustion chamber 10 and a distributor 20 housed in a casing 30. The combustion chamber is defined by an axisymmetric outer wall 14 and an inner wall 12, which extend in a nesting manner and pass through the end wall of the annular combustion chamber. 16 connections. [0003] The housing also has an inner wall 32 and an outer wall 31, and the inner wall 12 and the outer wall 14 of the combustion chamber are fastened to the inner wall 32 and the outer wall 31, respectively. [0004] The mixture of air and fuel is injected into the combustion chamber through multiple injectors, and the mixture is burned to generate the energy...
