Abstract: Aiming at the problem of serious flue gas wear and leakage on the heating surface of the low-temperature reheater in a
boiler, this paper analyzed the key reasons for the serious wear of the heating surface of the low-temperature reheater. After the
operation optimization and adjustment were difficult to achieve significant results, the optimization transformation of the heating
surface of the low-temperature reheater was completed, which greatly reduced the the wear of the heating surface of the lowtemperature
reheater, improved the reliability of the unit operation, and had certain reference significance for the transformation of
the same type of units.
