Abstract: The mechanism of blockage of GGH was introduced. The reformation method of GGH steam purge system of Wangting Power Plant was analyzed. The effect of the reformation was evaluated. It was proved that to increase the steam purge temperature and to use the upper and bottom soot blowers simultaneously can improve the blockage of GGH obviously, which can be used as reference for improvement of GGH blockage.
