The characteristics of outlet steam temperature and the metal temperature of the medium temperature platen superheater at different boiler loads was obtained in a 300 MWCFB boiler, the result shows that the imbalance rate of tube mass flux is determined by the structure of header and tube. Generally Z type arrangement is one of the reasonable types arrangement.
