| Abstract: | Transversal water-wall tube crack is an important factor to restrict the stable operation of ultra-supercritical boilers. It is significant to study the formation reasons and propose governance measures. The physical and chemical analysis, numerical simulation are employed for analyzing the reasons for transversal waterwall tube crack. Besides, the equipment modification and combustion optimization are employed for governing transversal water-wall tube crack. The governance results show that the cause speed of the transversal waterwall tube crack is slowed down sharply with the constant in-depth peak load regulation, and the governance effects are obvious. |
