Physical and Chemical Features of Hydrogen Combustion and Their Influence on the Characteristics of Gas Turbine Combustion Chambers

Hydrogen plays a key role in the transition to carbon-free economy. Substitution of hydrocarbon fuel with hydrogen gas turbine engines and power plants is an area growing interest. This review discusses combustion features adding as well its influence on characteristics chambers compared methane. The paper presents studies into pure or methane methane–hydrogen mixtures various contents. shows smaller ignition delay time higher laminar flame speed shift maximum value rich mixture, which has significant effect flashback inside burner premixer, especially at elevated air temperatures. Another feature increased temperature flame, can lead rate nitrogen oxide formation. However, wider concentration ranges contribute stable temperatures lower than those Along this, it been shown that even same adiabatic temperature, more oxides are formed indicates another mechanism for NOx formation addition Zeldovich mechanism. article also summarizes some results effects thermoacoustic instability, depends inherent nature pulsations during combustion. presented data will be useful both engineers who engaged solving problems designing devices scientists this field study.
