Summary In recent years, new ways of improving the combustion efficiency of fuel during gas turbine operations have been developed. The most significant has been the application of plasma technology for the combustion of fuel in gas turbine operations. Plasma is formed when gas is exposed to either high temperature or high‐voltage electricity. This technology is very promising and has proven to enhance the performance of gas turbines and reduce toxic emissions. Recent studies have shown the use of different types of plasma applications in gas turbine operations such as plasma torch, filamentary discharge, and nanosecond pulse discharge, whose results show that plasma technology has great potential in improving flame stabilization, the fuel/air mixing ratio, and flash point values of these fuels. These findings and advances have further provided new opportunities in the development of efficient plasma discharges for practical uses in plasma combustion of fuel for gas turbine operations. This article is a comprehensive overview of the advances and blind spots in the knowledge of plasma combustion of fuel during internal combustion engine operations. This review also focuses on applications, methods, and experimental results in plasma combustion of fuel in gas turbines.

“…The uniform nanosecond pulsed plasma discharge (NSP) in shock tube experiments demonstrated that plasma can ignite mixtures far below the explosion limit [27][28][29][30]. The subsequent engine tests [31,32] showed that microwave discharge extended engine lean burn limit by 20-30% with a small (50 mJ) energy input. Recent flame experiments [9,[33][34][35] also revealed that flame stabilization, ignition, and extinction limits can also be extended by PAC.…”

Since the 21st century, searching for new ways and approaches toimprove efficiency and to reduce exhaust gases of internal combustion engines has never been ceased. One of these innovation technologies is microwave plasma ignition. And this paper describes an applicable method for microwave plasma ignition. This method was realized in a metal closed cavity which imitates the combustion chamber in an internal combustion engine. The mixture of methane and air was successfully ignited by microwave plasma under 5~10 bar. The igniting process was recorded by a high-speed CCD camera and the curve of pressure was synchronously measured. These results were compared with the ignition process excited by a spark plug. The results show that the combustion ignited by microwave plasma is much more vigorous than by spark plug. The peak of pressure is higher in microwave plasma ignition. But the time characteristics of pressure curves show little difference between microwave plasma ignition and spark plug ignition.
