I have heard of at least 2 other plants with loss of heat recovery (i.e. increased temperature at the WHB outlet). No definitive explanation since both are still operating. Is this a common problem? Is it refractory-related? Dry-out/cure of refractory? Improper refractory?
Your other post mentions water-side fouling in the WHB. A good cleaning to remove surface scale and rust is essential before startup. See my post there.
