Abstract

The wastage of in-bed heat transfer surfaces has recently emerged as a potentially serious problem for both pressurized and atmospheric fluidized bed combustors. The experimental pressurized fluidized bed combustion facility at Grimethorpe has accumulated a considerable quantity of data covering the wastage of in-bed tubes obtained during a total of just over 3600 h of operation. The combustor operated with different tube banks, with some degree of wastage being experienced with each one. The data are described, evidence for possible solutions is presented, and plans for future tests at Grimethorpe to prove these solutions are outlined.
