Summary: In this study, a low environmental impact and innovative hybrid power plant for distributed energy is introduced. The plant combines a 30 kW micro gas turbine, a solar field, and a bottoming ORC system. The plant operates on hydrogen fuel with steam injection to reduce NOx formation. It also offers flexibility in generating electricity or providing heat through cogeneration.

Summary: The study validated a CFD methodology based on Large Eddy Simulation and Turbulent Flame Closure model to describe and capture the dynamics of flame extinction in typical turbulent lean premixed flames in gas turbine combustors under leanest operating conditions. The methodology was validated in a laboratory test case and an atmospheric swirl stabilized burner. It was then applied to a real scale combustor with a swirl lean burner.

Summary: The study demonstrates that by increasing the molar percentage of ammonia in the fuel, NO emissions rise dramatically, but further increasing ammonia beyond a certain threshold (about 12.5 molar percent) reduces NO emissions. Additionally, with the addition of ammonia, the overall temperature of the combustor decreases due to the lower heating value of ammonia compared to natural gas, while the overall efficiency of the combustor does not change significantly.

Summary: This study investigates the combined impact of hydrogen-enriched fuel and humidification on the energetic and environmental performance of a micro gas turbine plant. The results show that structural modifications are necessary for commercial micro gas turbine combustors to burn fuels with high hydrogen content. However, humidified cycles can improve combustion stability, electric power output, and plant efficiency.

Summary: Distributed energy systems play a key role in the transition to clean energy, especially when integrating renewable and traditional sources. Research on micro gas turbines focuses on improving their efficiency through modifications to the Brayton cycle, integrating multiple plants, and using cleaner fuels. Numerical modeling helps identify the potential and challenges of different layout solutions for these energy systems.

Summary: This paper investigates the opportunity to operate Micro Gas Turbines (MGTs) at partial-load and the impact of thermal storage and batteries on operating cost. An optimization algorithm is developed to determine the optimal operating profile of the system considering factors such as building size, weather, day of the week, and location. Experimental data characterizing the performance of a micro gas turbine is implemented. The study shows that operating at full-load mode results in savings up to 20%, and batteries between 1.5 and 2 kWh offer the best balance between installation costs and energy savings.

Summary: The effects of secondary oxygen ratio and secondary fuel ratio on combustion characteristics and emissions of a micro gas turbine combustor were investigated through numerical simulation. It was found that increasing the secondary oxygen ratio can reduce NO emissions, while increasing the secondary fuel ratio improves combustion efficiency.

Summary: This study investigates the behavior and combustion stability of an H2-enriched natural gas fuel premixed swirl flame in an industrial gas turbine. The results show that the flame exhibits different behaviors with increasing H2 blending ratio and is sensitive to inlet air temperature. Injecting recirculated flue gas is proposed to restrain flashback, and the laminar flame speed is recommended for burner design or control.

Summary: Experimental testing and validated CFD models were used to evaluate the performance of the FC4GT flameless gas turbine combustor under different operating conditions. The results showed that the combustor exhibited uniform flow fields and low NOx emissions when using methane or hydrogen as fuel. Volumetric histograms of temperature and oxygen were identified as useful tools for assessing combustion uniformity and NOx emissions.
