  • Patent number: 9523503
    Abstract: A combustion device (10) includes at least one combustion chamber (11) with a plurality of burners (B1, . . . , Bn) operating in parallel which produce in each case a flame (F1, . . . , Fn) which reaches into the combustion chamber (11), wherein each of the burners (B1, . . . , Bn), via a fuel distribution system (18), is supplied with a fuel from a fuel supply (16), which fuel distribution system (18) includes control elements (V1, . . . , Vm) for manual or controlled regulating of the fuel supply and/or fuel composition of individual burners (B1, . . . , Bn) and/or groups of burners (B1, . . . , B3; Bn?2, . . . , Bn). In a method of using the combustion device, a quick optimization or homogenization is achieved by a function (F) of the flame temperatures of the burners (B1, . . . , Bn) being provided in dependence upon the positions of the control elements (V1, . . .

  • Patent number: 8516825
    Abstract: In a method for reducing the NOx emissions from a burner arrangement comprising a plurality of burners (B1, . . . , Bn), in particular in a gas turbine, which burners (B1, . . . , Bn) are operated in parallel and each burner supplied fuel by means of combustion air to form a flame (F1, . . . , Fn), an effective drop is achieved in a simple way by virtue of the fact that at a predetermined time the flame temperatures of individual burners (B1, . . . , Bn) or burner groups or differences between the flame temperatures of individual burners (B1, . . . , Bn) or burner groups are measured directly or indirectly. The fuel supply to those burners or burner groups whose flame temperature exceeds a predetermined value for the flame temperature is selectively throttled in order to homogenize the flame temperatures of the burners (B1, . . . , Bn).

  • Patent number: 8346394
    Abstract: Power plant characteristics are operated in a flexible manner by controlling the power consumption of a CO2 capture and compression system. The impact of CO2 capture and compression on the capacity of a power plant can be minimized to maximize the electric power the plant can deliver to the power grid and the impact of CO2 capture and compression on the average plant efficiency can be reduced, by an operating method and a power plant, in which the power consumption of the CO2 capture system is used to control the net output of the plant.

  • Patent number: 8122726
    Abstract: A combustion chamber of a combustion system has a combustion space, a support structure, a support element, and a heat shield. The heat shield has at least two segments, and each segment includes a liner element facing the combustion space and has an edge region, a gap communicating with the combustion space being formed between edge regions of adjacent segments, and a retaining device. The retaining device fixes the respective liner element on the support structure via the support element and forms a flange region that fits over the edge region of the respective liner element. The retaining device forms a first cooling passage with the support element and has at least one through-opening in the flange region. A cooling gas flows through the through.opening from the first cooling passage to the edge region.

  • Patent number: 8007273
    Abstract: A premixing burner has a swirl generator with at least two burner shells (1) which jointly enclose an axia conically widening swirl space and delimit tangential air inlet slits (3) through which combustion supply air passes into the swirl space in which an axially propagating swirl flow is formed, and with fuel injection devices at least partially along the tangentially running air inlet slits (3). The fuel injection devices include a fuel line (6) separate from the burner shell (1) and which is firmly attached to the burner shell (1) so as to be longitudinally movable with respect to the burner shell (1) and releasable perpendicularly to the surface of the burner shell (1). In the burner shell (1), orifices (4) are provided, into which issue fuel injectors (7) which are provided along the fuel line (6) and which project beyond the circumferential edge of the fuel line (6).

  • Patent number: 7406827
    Abstract: In a fuel lance by means of which fuels can be injected, via at least two separate passages, into a combustion chamber alternately or simultaneously at an injection location arranged substantially at the lance tip, reliable operation is achieved, without the risk of flashbacks and also without coking, by virtue of the fact that the fuel lance, in addition to fuel, also passes purge air to the injection location, and that the purge air, at the injection location, is routed between the two fuel systems, in such a manner that these systems are shielded from one another by the purge air.
