We have discovered fireside pitting on the Morrison
corrugated furnace of one of our 400HP Cleaver Brooks
steam boilers. This boiler is only 2 years old and we
believe that the pits are defects from manufacturing
however we failed to notice them when we cleaned the
boiler after its first year of service. The pits are
throughout the entire furnace but are most prominant
at the bottom and towards the rear of the furnace. Some
of the pits are up to 1/8"deep and up to 1/2"in diameter.
Has anyone experienced this occurance?.
