Abstract: To grasp the wear characteristics of division panel superheater of pulverized-coal boilers and realize the operating optimization of its wear-reducing, integral model of the 330MW pulverized-coal boiler and fine full-scale model of division panel superheater were constructed in this paper to obtain the wear rate and wear area distribution of the pipes of division panel superheater under different operating parameters (boiler load, the vertical swing angle of burner and separate over fire air, the operating condition of coal mills). The results show that wear rate of the elbow of division panel superheater is much higher than that of the straight pipe, and the wear- prone areas are distributed in dots, while the straight pipe is distributed in blocks; the boiler load is the most sensitive to the degree of wear of division panel superheater, in the medium and high load range, the maximum wear rate of partition screen increases by more than 28% for every 5% increase in load; the maximum wear rate of division panel superheater increases with the increase of the vertical swing angle of burner and over fire air, and the effect of the over fire air is relatively high. When running four coal mills, the maximum wear rate of division panel caused by the operating condition of coal mills is within 10%, and it is better than the five coal mills fully operated under the same load.
