Abstract:
Vortexing limestone injection into furnace combined with calcium lime hydration in the downstream is the most promising technology for controlling SO2 emission. Particle imaging velocimetry(PIV)is used to measure the gas-liquid-solid three-phase flow field in a reactor. By image processing based on newly developed software, the number concentrations of sorbent particles and water droplets are presented. The measuring results are very helpful for better understanding the desulfurization mechanism and optimizing configurational and operational parameters in the hydration reactor.
