| Abstract: | The leakage probability of the high-pressure heater of thermal generator unit in power generation plants is very high. Especially for the 3^# high-pressure heater, the probability is higher than others for the complication of its operating situation and the significant effects brought with the changes of the load. In this paper, aimed at the power grid disconnection because of the leakage of the high-pressure heater in the operating 2 × 600 MW supercritical thermal generator sets and the gaping in the auto valve of the vent,the water seal method is proposed to deal with the leakage of the 3^# high-pressure heater online successfully by the arranging conditions of the system＇s pipe line under the conditions. |
