Boiler - an overview | ScienceDirect Topics

As previously mentioned there are primarily two basic watertube boiler designs that are selected by utilities in the United States : (1) subcritical drum-type boilers designed for a nominal operating pressure of 1900 or 2600 psig steam or (2) once-through supercritical units designed for 3800 psig steam.

The two basic watertube boiler designs that are selected by utilities in the United States are the subcritical drum-type boilers designed for a nominal operating pressure of 1900 or 2600 psig steam and the once-through supercritical units designed for 3800 psig steam [7]. Steam generators and their auxiliary components have many design criteria but the important issues are efficiency
