Abstract: The factors influencing on the reheater attemperating water were analyzed, which include the thermal load characteristics of boiler, the soot blowing optimization, the combustion adjustment, the operation mode of unit, the equipment management and others. Aiming at the typical condition of boiler, the characteristics of attemperating water were discoursed, and the relevant operation technology for controlling reheater attemperating water was proposed. Then the problem of the reheater attemperating water, the quantity of which was too large at long time, was solved successfully, and a more reliable reference was provided for reheater attemperating water control in power generation enterprise.

Key words: latent heat of evaporation, heat-absorbing share, saturation temperature, flue gas temperature, soot-blowing
