摘要： In an annular combustion chamber for a gas turbine, a combustion-chamber dome (14) is arranged upstream of an air-cooled combustion chamber (10). A first portion of an air flow (46) which comes from the compressor is admixed as combustion air to the combustion operation and cooling ducts (22; 24) feed a second portion of the air flow (46) coming from the compressor as cooling air into the combustion chamber (10). In this case, the cooling ducts (22; 24), which run at least in sections along the combustion chamber (10), have an entry (23; 25) into the combustion-chamber dome (14). The cooling ducts (22; 24) are designed for damping combustion-chamber oscillations in such a way that the acoustic impedance at the entry (23; 25) of the cooling ducts (22; 24) into the combustion-chamber dome (14) is minimized.

摘要： The object of the invention is to produce a method, for operating a gas turbine installation combustion chamber with liquid fuel, by means of which the NO.sub.X figures obtained when liquid fuel is employed are similar to those for gaseous fuels. The size of the burner is then also reduced. It is also an object of the invention to provide a corresponding appliance for carrying out the method.This is achieved in accordance with the invention in that the liquid fuel (38) is evaporated in at least two steps in a separate evaporative reactor (12). In this arrangement, the liquid fuel (38) is first atomized to a fuel vapor/liquid fuel mixture (61) by direct heat exchange with a first heat exchange medium (21) and is instantaneously evaporated in this process. The evaporation of the remaining residue of the liquid fuel (38) then takes place by indirect heat exchange with a second heat exchange medium (51). For this purpose, an evaporative reactor (12) is arranged vertically upstream of the combustion chamber (2) and is connected to it, which evaporative reactor (12) accommodates, at its inlet end, a dual-fluid nozzle (22) connected both to a liquid fuel line (19) and to a supply line (20) for a first heat exchange medium (21).
摘要翻译：本发明的目的是产生一种用于操作具有液体燃料的燃气轮机安装燃烧室的方法，通过该方法，当使用液体燃料时获得的NOX数值与用于气体燃料的NOx相似。然后燃烧器的尺寸也减小。本发明的另一个目的是提供一种用于执行该方法的相应装置。这是根据本发明实现的，因为液体燃料（38）在独立的蒸发反应器（12）中以至少两个步骤蒸发。在这种布置中，液体燃料（38）首先通过与第一热交换介质（21）的直接热交换而雾化到燃料蒸汽/液体燃料混合物（61），并在该过程中瞬间蒸发。然后通过与第二热交换介质（51）的间接热交换来进行液体燃料（38）的剩余残余物的蒸发。为此，蒸发反应器（12）被布置在燃烧室（2）的垂直上游并与其连接，该蒸发反应器（12）在其入口端处容纳连接两者的双流体喷嘴（22）到液体燃料管线（19）和用于第一热交换介质（21）的供应管线（20）。

摘要： In a burner for operating a combustion chamber, which burner essentially comprises a swirl generator (100) and a mixing section (220) arranged downstream of the swirl generator, this mixing section acting upstream of a combustion chamber (30), the swirl flow induced by the swirl generator (100) is directed via transition passages (201) into the mixing section (220). At the outlet of a mixing tube (20) belonging to the mixing section (220), the burner front (70) of the mixing tube (20) is provided with at least one torus-like notch (71) on the combustion-chamber side. Thus the stability of the backflow zone (50) can be intensified, which has a positive effect on the combustion from all aspects.

摘要： In a burner of the double-cone design for burning liquid (12) and gaseous fuels (16), the at least two sectional cone bodies (1, 2) overlap at least partly, the overlap angle (.delta.) increasing in the direction of flow of the burner, and the distance between the fuel injectors (15) and the air-inlet plane (21) into the burner increasing simultaneously with the increase in the overlap angle (.delta.). As a result, the air-inlet plane (21) and the fuel-injection plane (22) no longer coincide. Improved premixing of the gaseous fuel (16) with the combustion air is achieved by the invention, which leads to lower NOx emissions of the burner and to lower thermal loading of the burner front.

摘要： In a gas-turbine annular combustion chamber (4) which is arranged downstream of a compressor (1) and is equipped on its front plate with at least one row of premix burners (5) arranged in an annular form, in each case a combustion-air duct (15) designed as a diffuser leads directly downstream of the compressor outlet from the guide vanes (9) of the last compressor row to each burner (5), at the downstream end of which combustion-air duct (15) at least one longitudinal-vortex generator (16) is located, at least one fuel injection means (17) being provided in or downstream of the longitudinal-vortex generator (16). A mixing duct (19) which ends in the combustion chamber (4) and has a constant height (H) and a length (L) which corresponds approximately to twice the value of the hydraulic duct diameter (D) is arranged downstream of the fuel injection means (17). The overall size of the gas turbine in the region of the combustion chamber (4) can thereby be substantially reduced. In addition, the pressure loss between compressor outlet and turbine inlet is reduced.

摘要： In a burner of the double-cone design, bores (27) are arranged in the burner sickle (26), via which bores (27) the gaseous fuel (16), to the extent of about 3 to 8% of the total mass fuel flow, is mixed into the outer recirculation zone (28) of the burner. This leads to additional outer stabilization of the flame and to an extended operating range of the burner.

摘要： When carrying out a radiant heat exchange between two media, one medium being a hot gas (5) and the other medium being a gasification mixture (11) of fuel and steam, the device consists of a gasification vessel (1) which, for its part, consists of a reaction space (2), an intermediate tube (4) and a flow space (3). In the reaction space (2), the hot gases (5) flow away centrally in the direction of the intermediate tube (4) and the flow space (3). The gasification mixture (11) flows in the opposite direction out of the flow space (3) and the intermediate tube (4). This gasification mixture surrounds the hot gases (5) in such a way that the radiant heat exchange takes place between the two media (5, 11).
