Physical Modeling of Rotary Furnaces for Coke Calcination

摘要

Technical solutions for increasing the performance of rotary furnaces for petroleum coke calcination are proposed. One of the most effective ways is to mount intrafurnace agitating installations, namely, baffle plates, which are favorable for the intensification of coke agitation and its heat exchange with the lining and the furnace medium. The design of the baffle plates is developed by the physical simulation of coke motion within the drum of the rotary furnace. An analysis of the results for physical simulation is presented, and the efficiency of applying longitudinal baffle plates is proved. Their mounting in furnaces makes it possible to decrease the transverse and longitudinal segregation of coke and increase its residence time in the furnace by 10.2%, which positively affects the quality of calcined coke.
