“…The micro-mixing burner has been seamlessly integrated into an annular reverse-flow combustion chamber, as detailed in [106,109]. Furthermore, research has indicated that this micro-mixing (MM) combustor is not only capable of operating efficiently on hydrogen-rich syngas at a medium pressure of 0.6 MPa, as demonstrated in [110], but it also exhibits the ability to run on pure hydrogen while maintaining low NO x emissions, as highlighted in [111]. Several experimental and numerical studies have evaluated the effects of changing the fuel injector diameter on flame structure, and NO x emissions in low/high-energy density burner configurations [100,112].…”

The article reviews gas turbine combustion technologies focusing on their current ability to operate with hydrogen enriched natural gas up to 100% H2. The aim is to provide a picture of the most promising fuel-flexible and clean combustion technologies, the object of current research and development. The use of hydrogen in the gas turbine power generation sector is initially motivated, highlighting both its decarbonisation and electric grid stability objectives; moreover, the state-of-the-art of hydrogen-blend gas turbines and their 2024 and 2030 targets are reported in terms of some key performance indicators. Then, the changes in combustion characteristics due to the hydrogen enrichment of natural gas blends are briefly described, from their enhanced reactivity to their pollutant emissions. Finally, gas turbine combustion strategies, both already commercially available (mostly based on aerodynamic flame stabilisation, self-ignition, and staging) or still under development (like the micro-mixing and the exhaust gas recirculation concepts), are described.

“…For low power applications such as domestic boilers, a major drawback could be the need to considerably increase the volume of the combustion chamber due to the longer flames. Still, compact low emission turbulent burner designs could be based on flame aerodynamics, where several techniques such as cross flows, vortex generation, bluff bodies or swirling jets have been successfully used [27,55,56]. Another issue for such turbulent domestic boilers would concern the maximum possible inlet mass flows (and therefore inlet Reynolds number), considering the limitations of the standard blowers used to suction the air into the chamber.…”

“…It consists of 1600 miniature injectors and takes around 1600 kW of H 2 firing to generate 335 kW of shaft power (21% efficiency) by producing pneumatic and electrical power. In the experiment, a MM burner has been integrated inside an annular reverse-flow combustion chamber. , Another study has showed that this MM combustor is capable of running on both H 2 -rich syngas and pure H 2 while maintaining low NO x emissions in both cases . Funke et al have tested the GTCP36-300 APU with an injector diameter of 0.84 mm.…”

Strict emission control regulations call for continuous advancement in existing combustion and carbon-capture technologies to mitigate the rise in pollutants and greenhouse gases from fossil fuel combustion. Concurrently, improvements in combustion systems would also yield lower fuel consumption and operational cost with greater efficiency. This review addresses these concerns and presents the overview of different combustion technologies and burner designs for cleaner power generation in gas turbines. Emission characteristics are discussed and compared for different combustion concepts, including lean premixed air combustion and oxy-combustion. Various gas turbine burner technologies, including dry low NO x , enhanced-vortex, perforated-plate, and micromixer burners, are discussed extensively, in terms of their operating principle, fuel flexibility, and potential for superior performance under oxy-combustion conditions. Enhanced-vortex and micromixer burners show remarkable flame stability and fuel flexibility and are thus recommended for implementation with hydrogen enrichment in future oxy-fuel gas turbines. The fuel-flexibility approaches for clean energy production, such as hydrogen combustion, hydrogen-enriched combustion, syngas combustion, ammonia combustion, and fuel blending, are explored as well. With the vast recent advances in the techniques of hydrogen production and storage, hydrogen-fueled gas turbines seem to be the perfect choice for clean energy production. The adiabatic flame temperature is identified as a key controlling parameter for the design of oxidizer-flexible combustors in clean gas turbines.
