Abstract

Abstract: Based on the typical examples, the reasons of rotary air preheater rotor deformation of 600MW supercritical coalfired turbo generator unit in a power plant were analyzed. The technical safety measures of air preheater repairing without outage of the primary air fan were discussed. The technical safety measures for unexpected outage of the air preheater and its emergency repairing were formulated; and the experience on fast correcting the rotor deformation was summarized.

Key words: air preheater, rotor, deformation, rush-repair, hot wind flow backward
