Study on the performance of the burn pond for bubbling and hydrogen distribution

The burn pond is a relatively efficient and safe way to deal with the hydrogen emitted or leaked in experiments. The aim of this paper is to analyze the performance of the burn pond in bubbling and dispersing hydrogen. The numerical simulation is the primary method utilized in this study, with a small-scale experimental validation. And Taguchi method is proposed to process data and quantify the importance of each factor. The results show that the water depth affects the performance of the burn pond most significantly, accounting for more than 56 %, followed by the outer diameter of caps and the number of slots. In addition to these design factors, the velocity of hydrogen also has a considerable impact on the burn pond. Essentially, the four factors determine the size and kinetic energy of bubbles, which then directly affect the process of bubbling and hydrogen distribution. The conclusions provide an orientation for optimizing the parameters related to bubble caps and the burn pond.
