In small, low pressure boilers, steam-water separation can be established with the use of a large steam drum approximately half full of water. Natural gravity steam-water separation can be sufficient for this case. On the other hand, for high capacity, high pressure (HP) boilers, steam-water separation at the steam drum is accomplished with the use
