Abstract
The characteristics of Brown gas was experimentally studied in view of efficiency and flame propagation. For this study, the Brown gas stack with 7 cells was manufactured following the Brown gas related patents and reports. All measuring equipments were re-tested and calibrated by Korea Laboratory Accreditation Scheme (KOLAS) certified laboratories. Since the amount of produced gas is most crucial in determining the efficiency, we adopted two gas collecting methods such as bottle trap method and wet gas meter method. The energy efficiency of our own fabricated stack was measured to be 75%, which is comparable to general alkaline water electrolysis efficiency. In order to analyze the flame propagation characteristics of Brown gas, we measured the flame propagation pressure, velocity, and shape by using strain type pressure sensor, optical sensor, and high speed camera in conjunction with Schliren system, respectively. From the experimental results, it was found that the flame propagation behavior of Brown gas was almost the same as that of hydrogen and oxygen mixture gas in 2:1 molar ratio. Moreover, from the high speed camera analysis, we concluded that Brown gas flame exhibits explosion behavior as does mixture gas (
