Model Analysis of Pressure Fluctuation in the Pressurized Submerged Combustion

In this work, we will propose some improvements and innovations for Submerged Combustion, namely a Pressurized Submerged Combustion Technology. This paper introduces the Pressurized Submerged Combustion and some basic theoretical research.To understand better gas pressure fluctuations and their influence in flame stability, a mathematical model is developed in this paper, and its particular solution is elucidated. The results show that, the variations of pressure are influenced by bubbling which is a self-excited oscillation phenomenon. Increasing the damping of liquid motion is very helpful for stabilizing pressure fluctuations. The model can be used for guidance and optimization design of Pressurized Submerged Combustion equipments.
