Coil Type vs Shell Type Boile

Steam space. A coil type boiler is water tube design, the water travels through the coil and is surrounded with flue gases. The steam generated is directly fed to the process. There is no scope for steam storage as these are once through type boiler. Shell and tube type boilers have adequate steam space above the normal water level of the shell.

ONCE-THROUGH BOILERS - NUCLEAR POWE

1972-10-17 · A difficulty with `once-through` boilers in which the flow of water and steam is downwards, is that in the event of a failure of the boiler feed pump, the water would drain from the boiler and damage to the boiler could result. The temperature of the gas passing through the gas circulators to the inlet of the reactor core may also rise excessively.
