Gas-Solid Fluidization and Transportation Process Intensification for Coal Gasification by CPFD Method
The pulverized coal feeding vessel is an indispensable part of the pulverized coal conveying system. The pulverized coal feeding vessel of a gasification technology process adopts the method of bottom fluidization and side discharge,and the interior is equipped with complex internals and discharge pipes. Based on the mathematical model of gas-solid two-phase flow,this paper uses the CPFD(computational particle fluid dynamics) method to car-ry out fluid dynamics simulation on the fluidization state inside the feeding vessel,analyzes the flow characteristics of gas-solid two-phase flow in the pulverized coal feeding vessel,simulates the process of loose and conveying of pulverized coal in the feeding vessel,and studies the influencing factors and laws affecting the stability of pulver-ized coal conveying in the feeding vessel.
