Abstract In response to the increasing demand for environmentally sustainable alternatives to SF6 gas in arc-quenching applications, comparative studies are performed in the present work to explore the arc-quenching performance of a novel eco-friendly gas mixture composed of C4F7N, CO2 and O2. Through a combination of experimental studies and numerical modelling, the arc dynamic characteristics are firstly evaluated for ternary C4F7N/CO2/O2 gas mixtures with different mixing ratios. The results demonstrate that the variations in the volume concentrations of C4F7N and O2 only have an insignific

Sulphur hexafluoride (SF6) is extensively utilised as an insulating gas in power systems due to its highly electronegative properties. Nevertheless, SF6 is hindered by its elevated Global Warming Potential (GWP), which surpasses that of Carbon Dioxide (CO2) by a value of 23500. The research evaluates the breakdown voltage of CO2+Oxygen (O2) and SF6+O2 gas mixture as alternative insulation media during positive lightning impulses test.

Abstract Oxyfuel combustion is considered as one of the most promising technologies to facilitate CO2 capture from flue gases. In oxy-fuel combustion, the fuel is burned in a mixture of oxygen and recirculated flue gas. Flue gas recirculation increases the levels of fireside CO2, SO2, Cl and moisture, and thus promotes fouling and corrosion. It has been suggested that oxide scales developing in O2/CO2/H2O atmospheres are not well protective and internal carburization may occur.
