    • A burner, particularly for a gas turbine, includes a catalytic combustion chamber and a performer/reformer (24). The combustion chamber has an essentially cylindrical extent in a flow direction of a fuel and a catalytically active coating (12) on a wall facing the fuel for oxidation of the fuel. A particularly low nitrogen oxide content of burner exhaust gas is achieved as a result of the catalytically induced combustion of the fuel. At the same time, in contrast to known primary measures for nitrogen oxide abatement, the flow resistance in the burner is not increased by the coating of the wall. Therefore, when the burner is used in a gas turbine, a particularly high efficiency together with a low nitrogen oxide emission can be achieved.
    • 特别是用于燃气轮机的燃烧器包括催化燃烧室和执行器/重整器(24)。 燃烧室在燃料的流动方向上具有基本上圆柱形的程度,并且在面向燃料的壁上用于氧化燃料的催化活性涂层(12)。 作为燃料的催化燃烧燃烧的结果,燃烧器废气的氮氧化物含量特别低。 同时,与已知的氮氧化物消除的主要措施相反,燃烧器中的流动阻力不会因壁的涂覆而增加。 因此,当在燃气轮机中使用燃烧器时,可以实现特别高的效率以及低的氮氧化物排放。

    • A gas turbine can achieve comparatively low emissions of nitrogen oxide. One disadvantage particularly of a catalytic combustion chamber is that, for example for natural gas, the ignition temperature necessary for combustion is in the region of about 400 .degree. C. The use of an auxiliary burner, which constitutes a disadvantageous source of nitrogen oxide, has therefore been heretofore unavoidable. In order to eliminate that disadvantage, a gas turbine for the combustion of a fuel gas, particularly with catalytic combustion of the fuel gas, includes a conduit system for drawing off part of the fuel gas, guiding it through a catalytic preforming stage to convert a hydrocarbon contained in the fuel gas into an alcohol and/or an aldehyde and subsequently feeding it to the fuel gas again in order to lower its ignition temperature. In this way, the comparatively easily igniting fuels alcohol and/or aldehyde are obtained from the fuel gas in the preforming stage. A fuel gas intermixed with these materials therefore ignites at a considerably lower ignition temperature than a fuel gas without preformed constituents.
    • 燃气轮机可以实现相对较低的氮氧化物排放。 特别是催化燃烧室的一个缺点是,例如对于天然气,燃烧所需的点火温度在约400℃的范围内。构成氮氧化物不利源的辅助燃烧器的使用具有 因此以前是不可避免的。 为了消除这种缺点,用于燃料气体燃烧的燃气轮机,特别是燃料气体的催化燃烧,包括用于抽出部分燃料气体的导管系统,引导其通过催化预成型阶段,以将 将包含在燃料气体中的烃转化成醇和/或醛,然后再次将其送入燃料气体中以降低其着火温度。 以这种方式,从预成型阶段的燃料气体获得比较容易点燃的乙醇和/或醛的燃料。 因此与这些材料混合的燃料气体在比未燃料成分的燃料气体低得多的点燃温度下点燃。
