摘要： A combustion chamber (1), in particular in a gas turbine, has at least two burners (A-H) that are connected to a fuel supply (3) via controllable fuel valves (2′ and 2). Each burner (A to H) is assigned at least one optical measuring device (4) for detecting chemiluminescent radiation, and the combustion chamber (1) is assigned a pressure sensor (7) for detecting a combustion chamber pressure. The optical measuring device (4) and the pressure sensor (7) are connected to a computing and control device, which calculates a correlation value from the incoming measured values. A high correlation value signifies that the associated burner is prone to pulsation. The computing and control device (6) is designed in such a way that it determines the burner or a burner group with the highest correlation and controls the associated fuel valve(s) in such a way that more fuel is fed to the respective burner or the respective burner group, and the pulsation tendency thereof is thereby reduced.

摘要： A modification method for reducing emissions from an annular shaped combustor of a gas turbine plant, having uniformly spaced circumferentially mounted premix burners (20), includes the steps of: removing at least one burner (20), thereby disrupting the spatial uniformity of the remaining the burners (20); and modifying the combustor air distribution system so as to compensate for the increased burner pressure drop of the remaining burners, thus enabling the modified combustor to operate at a load equivalent to the unmodified combustor. Emission reduction is enabled by the increase in the gas velocity of the burner for a given load further enabled by the flame stabilizing effect of disrupting the spatial uniformity.

摘要： A premix burner with staged liquid fuel supply is described having at least two partial cone shells which on the radial side form the boundary of a swirl chamber which axialwards conically widens, which partial cone shells are arranged in a partially overlapping manner, the center axes of the partial cone shells of which extend with offset effect in relation to each another, and the mutually overlapping partial cone shell sections of which enclose in each case an air inlet slot which extends tangentially to the swirl chamber, with a burner lance which projects axialwards into the swirl chamber, which lance provides means for feed of liquid fuel into the swirl chamber, and also with further means for feed of liquid fuel which are provided in the region of the air inlet slots. As such, additional means for feed of liquid fuel along at least one air inlet slot are formed and arranged in such a way that the liquid fuel delivery, which is conditioned by the further means, takes place in the form of a fuel spray which propagates perpendicularly to the tangential longitudinal extent of the air inlet slot, and also a fuel spray which propagates perpendicularly to an air flow which is directed through the air inlet slot.

摘要： A method for operating a gas turbine (11), which is used especially in a combined-cycle power plant (30), includes inducting and compressing air by the gas turbine (11), the compressed air is fed to a combustor (18, 19) for the combustion of a syngas which is produced from coal, and the hot gases which result during the combustion are expanded in a subsequent turbine (16, 17), performing work, wherein some of the compressed air is separated into oxygen and nitrogen, and the oxygen is used in a coal gasification plant (34) for producing the syngas. With such a method, a reduction of the NOx emission is achieved without noticeable loss of output and flexibility of operation by a gas turbine (11) with reheating being used, which includes two combustors (18, 19) and two turbines (16, 17), wherein in the first combustor (18) syngas is combusted, using the compressed air, and the resulting hot gases are expanded in the first turbine (16), and wherein in the second combustor syngas is combusted, using the gases which issue from the first turbine (16), and the resulting hot gases are expanded in the second turbine (17), the two combustors (18, 19) are operated with undiluted syngas, and the flame temperature (TF) in the first combustor (18) of the gas turbine (11) is lowered compared with the operation with natural gas (TNG), while the second combustor (19) is operated largely in the normal operation (TNG) which is designed for natural gas.
