OPERATING EXPERIENCE WITH A HIGH-TEMPERATURE PSEUDO-2D FLUIDIZED BED REACTOR DESIGNED ESPECIALLY FOR DETAILED LOCAL DATA COLLECTION

摘要

This paper reports practical experience from the high-temperature operation of a pseudo-2D fluidized bed reactor running redox reactions typically occurring in a Chemical Looping Combustion process.The reactor was designed for the primary purpose of providing detailed local data for the validation of reactive multiphase flow models.For this purpose, the pseudo-2D bed was equipped with multiple measurement ports which allowed for the simultaneous measurement of temperature, pressure and gas composition at various positions within the bed.Multiple unforeseen challenges were encountered and solved (within practical limits) during this first-of-a-kind experimental campaign.Extensive recommendations are given to guide future experimental campaigns aiming to build on this work.
