内循环流化床颗粒循环速率实验研究
Experimental Study on the Solid Circulation Rate in an Internally Circulating Fluidized Bed
摘要
Abstract
The solid circulation rate was experimentally studied by heat-particle tracing and correlation function method.The effects of superficial gas velocity , diameter of orifices on the riser wall and height of the riser on the solid circulation rate were studied in an internally circulating fluidized bed reactor. The results showed that the circulation rate Gs was in the range of 15 to 70 kg/(m2·s) . With an increase in the gas velocity,the fluidization of the particles was enhanced and resulted in an increase in Gs. With a fixed number of orifices , increased orifice diameter decreased the friction of the particle circulation and increased the circulation rate. The solid circulation rate had a maximum with the riser height 265 mm when the riser heath changed in the range of 235 mm to 295 mm.关键词
