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