Poor heat transfer effect of the rotary air preheater was considered as the main reason for the phenomenon occurs in a 600 MW ultra supercritical unit boiler:low hot air temperature and high exhaust gas temperature.To solve this problem
300 mm height carbon steel heat storage component was added to the heat section of preheater.Results show that
heat transfer is significantly enhanced.Temperature rise of the primary and secondary air
and its drop of the delayed side both meets the design value.Heat exchange efficiency of the flue gas side reaches 70.78%
