I think your piping system will take care of the derating of your boiler(s) - if carryover in your steam drum doesn't. Your boiler(s) are designed to operate at a given pressure and the internal water circulation patterns are a function of that pressure (range). Circulation in a natural circulation boiler is created in a two fold manner.
