| Abstract: | The prevalent over-temperature caused tube bursting of high-temperature heating surface in large-capacity boilers in recent years has seriously endangered the safe and economic operation of units. This paper analyzes the causes of the over-temperature problem,describes the mechanism of heating surface tube failures due to overheat or high-temperature corrosion, and puts forward some countermeasures. |
