Abstract [eng] |
Addressing the escalating global energy demand, compounded by the ongoing political scrutiny of certain fossil fuels and humanity's persistent drive toward cleaner energy solutions, has led to an increased reliance on non-fossil fuel alternatives. Despite this shift, the overarching objective of achieving globally widespread carbon-free fuel for energy applications still needs to be achieved, trapping the industry in a transitional phase. To meet fuel demands during this transitional period, one viable option is the utilization of low-calorific gases, such as biogas, with low methane concentrations in the mixture. While those mixtures are notoriously challenging to ignite or even stay non-combustible under standard conditions, they necessitate assistance to enhance or enable the combustion process. Using propagators such as non-thermal plasma helps not only with refining ignition or augmenting flame propagation speed but also increases rates of radical emissions. Such radicals as OH* and CH* are known to be significant influencers on the combustion process, as well as C2* is an essential marker of soot generation. This investigation focus on scrutinizing the impact of plasma parameters on biogas composition with low methane content in it, explicitly examining chemiluminescence and emissions of OH*, C2*, and CH* radicals in both plasma and flame, assessing combustibility under lean mixture conditions, and elucidating the conditions for increasing the stability of the combustion process. |
