| Abstract: | The situation of ash clogging in air heater of boilers for three 600 MW units in second-phase project of Beilun Power Generation Co Ltd has been presented, and various factors affecting the resistance variation in air heater being analysed, putting forward technical measures for effectively suprressing rapid resistance increase in the air heater. After technical retrofit, on-line water flushing of the air heater has been realized, solving the problem of water flushing during shut-down. |
