    • A method and installation are disclosed which can, for example, provide for reliable, low-Nox-emission operation of a gas turbine installation with hydrogen-rich fuel gas. An exemplary gas turbine installation includes an arrangement for flue gas recirculation into a compressor inlet and for fuel gas dilution. Oxygen content in combustion air can be reduced by recirculation of recooled flue gas, and the fuel gas can be diluted with compressed flue gas. The oxygen reduction in the combustion air can lead to minimum residual oxygen in the flue gas which can be used for fuel gas dilution. As a result of the flue gas recirculation, water content in the combustion air can be increased by feedback of the water which results as a combustion product. The oxygen reduction, increased water content, and fuel dilution can reduce the flame velocity of hydrogen-rich fuel gases and enable a robust, reliable and low-emission combustion.
    • 公开了一种方法和装置,其可以例如提供具有富氢燃料气体的燃气轮机装置的可靠的低NOx排放操作。 示例性的燃气轮机装置包括用于烟道气再循环到压缩机入口和用于燃料气体稀释的装置。 燃烧空气中的氧含量可以通过再冷却的烟道气的再循环来减少,燃料气体可以用压缩的烟道气稀释。 燃烧空气中的氧气还原可导致烟道气中的最小残留氧气,可用于燃料气体稀释。 作为烟道气再循环的结果,可以通过作为燃烧产物的水的反馈来增加燃烧空气中的含水量。 减少氧气,增加含水量和燃料稀释可以降低富氢燃料气体的火焰速度,并实现坚固,可靠和低排放的燃烧。

    • The invention provides an electron beam device 1 comprising at least one field emission cathode 3 and at least one extracting electrode 5, whereby the field emission cathode 5 comprises a p-type semiconductor region 7 connected to an emitter tip 9 made of a semiconductor material, an n-type semiconductor region 11 forming a pn-diode junction 13 with the p-type semiconductor region 7 a first electric contact 15 on the p-type semiconductor region 7 and a second electric contact 17 on the n-type semiconductor region 11. The p-type semiconductor region 7 prevents the flux of free electrons to the emitter unless electrons are injected into the p-type semiconductor region 7 by the pn-diode junction 13. This way, the field emission cathode 3 can generate an electron beam where the electron beam current is controlled by the forward biasing second voltage V2 across the pn-diode junction. Such electron beam current has an improved current value stability. In addition the electron beam current does not have to be stabilized anymore by adjusting, the voltage between emitter tip 9 and extracting electrode 5 which would interfere with the electric field of electron beam optics. The present invention further provides the field emission cathode as described above and an array of field emission cathodes. The invention further provides a method to generate at least one electron beam.
    • 本发明提供一种包括至少一个场发射阴极3和至少一个提取电极5的电子束装置1,由此场发射阴极5包括连接到由半导体材料制成的发射极尖端9的p型半导体区域7, 在p型半导体区域7上形成p型二极管结13的n型半导体区域11,p型半导体区域7上的第一电接触15和n型半导体区域11上的第二电接触17。 p型半导体区域7防止自由电子束流到发射极,除非电子被pn二极管结13注入到p型半导体区域7中。这样,场发射阴极3可以产生电子束,其中 电子束电流由跨越pn二极管结的正向偏置第二电压V 2控制。 这种电子束电流具有改善的电流值稳定性。 此外,电子束电流不必通过调节发射极尖端9和提取电极5之间的电压,这将干扰电子束光学器件的电场。 本发明还提供如上所述的场致发射阴极和场发射阴极阵列。 本发明还提供了一种产生至少一个电子束的方法。
