To meet the Chinese government’s energy-saving and emission-reduction policies, flexible peak regulation is necessary for traditional coal-fired boilers. Flexible peaking leads to large changes in boiler load, which affects safety of water wall. In this paper, a 1000 MW ultra-supercritical unit was tracked three years, effective data were selected study temperature characteristics wall under regulation. The results show that lower greater fluctuation distribution spiral more uniform. position valley value rear found, load even also found. change front vertical most complex all walls. 643.9 case showed different behavior side walls heated evenly loads. found through statistical analysis. fitting equation rule presented. higher better equations. Finally, paper gives some advice on how avoid deviation wall, detailed research highlights safe running
