Abstract: The steam drum of a high pressure steam generating unit, and particularly one subject to frequent thermal cycling, is divided into compartments. Each compartment is, to a large extent, fluidly isolated from the others. Furnace wall steam-water mixture is admitted to an intermediate compartment which is spaced from the inner surface of the drum wall by an annular outer compartment extending about substantially the entire inner circumference of the drum. The majority of the steam-water mixture is conducted, via the intermediate compartment, through steam separators and into an inner compartment. A small part of the mixture may be allowed to pass from the intermediate compartment into the outer compartment and then into the downcomer to avoid the formation of a water level in the outer compartment.
