Abstract
The tube thickness map of water wall has been measured in a commercial circulating fluidized bed combustor (200 ton steam/hr, $4.97{\times}9.90{\times}28.98m$ height) with ultrasonic method and tube erosion has been discussed. Severe tube erosion took place in the splash region on all waterwalls including wingwalls. Erosion on the lower part of front and rear walls, close to both side walls, was more serious than other places. Erosion of some tubes around the gas exit was found to be noticible. Tube erosion increased on the wingwall as the position of the tube become closer to the center of the combustor crosssection.
