The Effect of DBD Plasma on Hydrocarbon Fuel Reforming and Change in Flammability Limits

DBD 플라즈마 개질에 의한 탄화수소계 연료 화염의 가연한계 변화

An experimental study was conducted to find the effect of DBD plasma on the flammability limits of inert-gas-diluted fuel. The results showed that the concentration of diluting nitrogen at flammability limit increased when nitrogen-diluted methane and propane were reformed by plasma, while it decreased when nitrogen-diluted ethylene was reformed by plasma. Gas chromatography results suggested that the fuel type dependence of flammability limits is due to the difference in the concentrations of hydrogen and hydrocarbon species in reformed fuel.
