Strong HCl effect on tube wastage in a simulated bubbling fluidized bed environment

This paper reports initial results from a laboratory fluidized bed test rig where HCl gas was incorporated into the bed. The rig simulates the particle hammering interactions between in-bed particles and tubes within bubbling fluidized bed combustors (BFBCs). A significant increase in material wastage rates in the presence of HCl was found at 450°C as well as at 200°C. The detrimental effect decreased with decreasing HCl concentration.
