Embodiment Construction

[0044] For the sake of clarity, the dimensions of the components represented in these figures do not correspond to their actual dimensions or their ratios of actual dimensions, or to exact shapes when these shapes do not depend on the invention. Also, when some components of the described apparatus do not directly participate in carrying out the invention, they are shown only symbolically or in principle, or not at all. This is a special case of the fuel injection system, which is located in the center of the air supply swirler, but is not shown in order to reveal more clearly the components directly relevant to the invention. In addition, the same reference numerals shown in different drawings denote the same components or components having the same function.

[0045] The present invention can be applied as figure 1 turbine shown. This turbomachine includes a turbine combustor 100 , a compressor 200 and a turbine 300 .

[0046] The turbine combustor 100 itself comprises a ...

Abstract

The invention relates to a self-adapting gas turbine firebox with variable geometry, comprising at least one system with a variable opening for automatically adjusting a configuration of the combustion inside a combustion chamber (101) according to an air temperature, particularly air from a compressor. The adjustment is performed by a thermosensitive element that controls at least one section towards the combustion chamber, for the air that participates in the combustion of the fuel, or participates in a dilution of the gases effective inside the combustion chamber.

Description

technical field [0001] The invention relates to an adaptive gas turbine combustor with variable geometry and a turbine comprising such a combustor. Background technique [0002] It is well known that the combustion of fuel in the combustion chamber of a turbine has emission characteristics of carbon monoxide, combustion residues and nitrogen oxides which vary according to the power setting of the turbine. First, carbon monoxide and combustion residue emissions increase dramatically when the power setting is lowered, and nitrogen oxide emissions increase when the power setting is increased. When the turbine is an aircraft turbojet, a high power setting is used for takeoff and then cruising, and a low power setting is used for landing and taxiing, which also corresponds to the in-flight re-ignition conditions of the turbojet. To reduce these emissions regardless of power settings, variable geometry gas turbine combustors can be considered. Such a combustion chamber with vari...
