How Water Tube Type Steam Boilers Work | Miura Boilers

Water-tube boilers also have a downcomer tube that connects the steam drum to the feedwater drum. If the steam cools and condenses back into water droplets, that water can drain from the steam drum to the feedwater drum via the downcomer tube. This allows that water to re-enter the boiler's water supply, go back into the tubes, and once again
