Description
Semi flashcoil superheated boilers from Foster Wheeler. Acetone burners.

Steam is provided at 375 PSI, 800F degree superheat by sixteen semi-flashcoil boilers of a configuration of a bank of flash coils being given feedwater and giving flash steam to a drum. These boilers are fired by acetone. Feedwater heating is accomplished first by a heat exchanger using exhaust steam from the low pressure cylinder exhaust, followed by banks of economisers located inside the exhaust chimneys. Boiler drafting is forced and is accomplished by centrifugal blowers being driven by high speed engines.
Condensing of the steam is accomplished by banks of radiative condensers arranged in series and placed inside two long air conduits inside the ship's superstructure, cold air is forced through from the outside at high speed by fans driven by small steam turbines and is passed over the condensing grids. Condensate is removed by engine-driven wet air pumps and air is ejected via airpumps tandemed to these, auxiliary duplex pumps are available when the main engines are not turning.
Boiler feedwater is accomplished by engine-driven feedwater pumps that are run via jackshafting off of gear reduction. Again standalone backup pumps are available multitudinous in number. Boiler feedwater metering rate is accomplished by makeup meters and thermohydraulic water level indicators on the boilers as well as the usual sightglasses; although these boilers are of the flash-coil type they run a nominal water level in the steam drum itself. Control of feedwater introduction is manual.
