Numerical investigation on cold flow dynamics of supercritical water fluidized bed reactor with inclined distributor:Design and scale up
文献摘要：
Supercritical water fluidized bed reactor(SCWFBR)is a novel concept for the gasification of coal and biomass to produce hydrogen.In this work,to enhance the mixing in the axial direction,an inclined dis-tributor is introduced to optimize the flow dynamics in SCWFBR with partitioned fluid supply.Through numerical simulations based on the two fluid model(TFM),the effects of the inclined distributor struc-ture and operating parameters on the solid distribution and the residence time are evaluated with the optimal values determined.Numerical results show that,area ratio=2:1,SCW velocity ratio=3:1,flow ratio=3.36:1 and inclination angle=20° are the optimal design in this paper.A predictive correlation of the minimum fluidization velocity for the improved SCWFBR is also proposed based on the numerical data.The average error between the correlation and numerical simulation results is approximately 1.4％which strongly demonstrates its capability.Finally,based on the optimal design,the lab-scale reactor is further scaled up and the studies about two scale-up rules are carried out.Only the cold flow is simulated in this study without considering chemical reaction which would be involved in future work.
