Experimental study on the gas-particle two-phase flow characteristics in a fluidized bed SCR denitrification reactor

It is difficult to accurately measure the parameters of solid particles in the experiment of the gas-solid fluidized bed. The numerical simulation plays an important role to accurately describe flow characteristics in the fluidized bed. Combined with the research work of the research group, this paper analyzes the application of numerical simulation of fluidized bed from the aspects of gas-solid coupling algorithm, drag model, flow characteristics, and reaction characteristics based on the previous studies. The specificity improvement of the gas-solid coupling algorithm and the regional application of the drag model is the trend of the recent development of numerical simulation. Previous studies mainly focus on the gas-solid two-phase flow field characteristics in the traditional fluidized bed, but few on the complex flow characteristics such as gas-solid reverse flow and the coupling with reaction characteristics. It is of great significance for designing a novel fluidized bed reactor to realize gas-solid continuous reaction to establish and improve the numerical simulation method of gas-solid non-catalytic reaction.

In the current study, an experimental study on two-phase flow at different orientations is carried out at the Fluids Laboratory, Memorial University of Newfoundland (MUN). Three different orientations are used. They are horizontal, vertical and slanted orientation respectively. The experimental unit consists of pipes that are three inches (DN 80) in diameter and are capable of producing many various regimes of gasliquid flows. The experimental unit has sensors to measure the pressure, temperature and volume flow at numerous locations. Experiments are conducted for two-phase flow (bubble and slug flow). The new experimental data can provide valuable insights on the viscous effects with many flow regimes, phase compositions and direction of flow. The results of this research provide valuable new experimental data on two-phase flow characteristics for many flow regimes that can improve the safety and efficiency of wellstream flows.
