Findings And Result In Operating A Steam Boiler

High pressure boiler explosions/rupture - NavWeaps

On 4 boiler DD, I kept one boiler on the line - the other three were secured as soon as 'finished with engines' was received from the bridge. Fires were secured in those three boilers and the steam pressure decayed to atmospheric in a matter of hours. The lower drums were 'bottom blown' at about 600 psi to get rid of feed water impurities.
