        Three-drum boiler - Wikipedia

        Three-drum boilers are a class of water-tube boiler used to generate steam, typically to power ships.They are compact and of high evaporative power, factors that encourage this use. Other boiler designs may be more efficient, although bulkier, and so the three-drum pattern was rare as a land-based stationary boiler.

          Modern water tube boilers, on the other hand, are subjected to increasingly higher levels of heat flux, temperature, and pressure. So the designers can no longer ignore the process of circulation of water and steam in the boilers. Inadequate circulation of water would fail to remove heat from the tube surface at a sufficient rate, which may
