ABSTRACT:
In order to avoid plugging the air passageways (42a) of fuel injectors (42) with carbon particles or lumps in a gas turbine engine (10), the gas turbine engine (10) includes an annular combustor (18) having radial dilution air injection. The gas turbine engine (10) also includes a rotor (12) having turbine blades (14) and a nozzle (16) adjacent the turbine blades (14) which is adapted to direct hot gases of combustion at the turbine blades (14) to cause rotation of the rotor (12). The annular combustor (18) is disposed about the rotor (12) and has an outlet (20) to the nozzle (16), spaced inner and outer walls (22 and 24), and a generally radially extending wall (26) connecting the inner and outer walls (22 and 24). The gas turbine engine (10) further includes a housing (28) substantially surrounding the annular combustor (18) in spaced relation to the inner, outer, and radially extending walls (22, 24 and 26) to define a dilution air flow path (30). The annular combustor (18) has a combustion annulus (36) defined by the inner, outer, and radially extending walls (22, 24 and 26), and a plurality of radially disposed air blast fuel injectors (42). The gas turbine engine (10) also includes dilution air holes (48) for bleeding air into the combustion annulus (36) to mix with the hot gases of combustion. With this arrangement, the gas turbine engine includes a screen or wire mesh for preventing matter potentially obstructive to an air passageway of a fuel injector from passing from a dilution air hole into the air passageway.
