Analysis of the causes of leakages and preventive ...

The reasons for the failures of a boiler water-wall tube used in the thermal power plant were investigated in this paper. The material of water-wall tube was made of medium-carbon steel SA-210 Grade C which is pearlitic heat-resistant steel with a working temperature lower than 500 °C and is widely used in boilers tubes.

Automatic boiler tube leak detection with deep ...

Boiler tubes in power plants develop defects including creep and thermal fatigue damage that can lead to fluid leakage over the operation period. Such leakage is the main cause of outages and power generation losses in thermal power plants. Therefore early detection of leaks in boiler tubes is necessary to avoid more than 60% of boiler outages. To monitor and detect tube leaks in real-time ...
