Embodiment Construction

[0029] exist figure 1 A gas turbine installation 2 with a compressor 4 and a turbine 6 is shown schematically in simplified form, wherein an air supply 8 and an annular combustion chamber 10 are arranged in flow communication between the compressor and the turbine. Compressor 4 is coupled to turbine 6 by means of a shaft 12 , wherein shaft 12 drives a generator (not shown here) for generating electrical energy. The shaft 12 is arranged in the center of an annular combustion chamber 12 having a plurality of burners 14 . Furthermore, the gas turbine plant 2 has a bypass line 16 with a valve 18 which branches off from the air supply 8 to bypass the burner 14 and connects the burner 14 of the annular combustion chamber 10 with the turbine 6 In the region formed between it leads into the annular combustion chamber. The valve 18 is signal-coupled to a control circuit 22 by means of a control line 20 .

Abstract

The invention relates to a gas-turbine system (2) of a power plant, said system comprising: a compressor (4); an annular combustion chamber (10) having a burner (14); and a turbine (6) coupled to the compressor (4). The gas turbine system (2) has a bypass line (16) for compressed air, said line bypassing the burner (14) and having a flow connection parallel thereto.

Description

technical field [0001] The invention relates to a gas turbine installation of a power plant having a compressor, a turbine coupled to the compressor, and an annular combustion chamber. Background technique [0002] A gas turbine system usually has a compressor and a turbine, which are coupled to one another by means of a common shaft. A combustion chamber is arranged between the compressor and the turbine, in which the combustion of the gaseous fuel takes place with the addition of air compressed by the compressor. The exhaust gases produced in this way expand in the turbine, which causes a rotational movement of said turbine. Also coupled to the shaft is a generator by means of which electrical energy is generated. In order to ensure a relatively efficient combustion, the combustion chamber is designed as an annular combustion chamber. In other words, the combustion chamber is arranged rotationally symmetrically with respect to the shaft that couples the compressor to th...
