Optimize Steam Temperature Control Loops to Improve Availability. Increased cycling places additional mechanical stresses on boilers and heat recovery steam generators (HRSGs), particularly influenced by underperforming superheat and reheat loops. The suboptimal performance of these important loops can increase the frequency of tube leaks.
