High Pressure Boilers are entirely water tube design boilers for high-pressure steam Water circulation through the boiler is also either natural circulation

Steam/water circulation design – KTH – Energiteknik

The steam pressure limit is based on the fact that when the steam pressure in the boiler for a natural circulation boiler is about 5 the boiler high.
