| Abstract: | The Hp heater is an important auxiliary of a thermal power plant, and its defects will seriously impact the safety and economic operation of generating units. By dissecting and testing an abandoned vertical HP heater of a 125 MW unit in Yunfu Power Plant, the regularity of defect location was found out and the causes of defects analyzed. Suggestions for the operation and testing of similar domestic HP heaters are included. |
