Towards highly-efficient hydrogen gas turbines

人们对绿色氢的兴趣日益浓厚，因此需要研究和开发能够容纳氢的燃烧系统。一项有前景的技术是低排放燃气轮机，它是电力市场的关键参与者。然而，氢燃气轮机容易受到热声不稳定现象的影响，产生巨大的噪音，并可能损坏设备。该项目首次全面研究了氢燃料对燃气轮机相关条件下热声不稳定性的影响。通过检验通常用于设计燃气轮机的低阶模型，该项目可以显著推进该领域的发展，并促进绿色氢作为燃料来源的采用。

The increasing interest in green hydrogen has led to a need for research and development in combustion systems that can accommodate hydrogen. One promising technology is low-emission gas turbines, which is a key player in the electricity market. However, hydrogen gas turbines are susceptible to a phenomenon called thermoacoustic instability, causing loud noise and can damage equipment. This project represents the first comprehensive study of the effects of hydrogen fuel on thermoacoustic instability under conditions relevant to gas turbines. By examining low-order models, commonly used for designing gas turbines, this project can significantly advance the field and facilitate the adoption of green hydrogen as a fuel source.
