Experimental Study of Desulfurizaiton Performance of Spouted Bed with Porous Draft Tube

Abstract:

For the flue gas semi-dry desulfurizaiton technology, a new type of spouted bed with porous draft tube was put forward in this paper. The desulfurizaiton performance of it was studied, and some effects on SO² removal efficiency were examined, such as molar ratio of Calcium to sulphur, inlet concentration of SO², bed height, gas inlet temperature and approach to saturation temperature etc. This study also compared the SO² removal efficiency of spouted bed with porous draft tube with the nonporous one. The results show that the spouted bed with porous draft tube has better desulfurizaiton performance, the SO² removal efficiency of which is higher than the one with nonporous draft tube and the optimal operation condition was obtained for industrial application.
