: As long as the tubes, tubesheets, drums and all associated hardware are in good shape and passes inspections, there is no reason to replace it due to age.
I have seen well maintained boilers in manufacturing plants and utility plants over 60 years old.
Upgrades are normal due to age, like new combustion controls to increase efficiency, or comply with new air permits.
