Abstract
A vertical evaporator has an inner tube containing a heat exchanger for heating water and an outer tube which is coaxial with and surrounds the inner tube, forming a sealed system and leaving a peripheral space between the two tubes. The inner tube has bottom outlets through which steam and water droplets generated by heating water by the heat exchanger are ejected. A helical fin is attached to the outer surface of the inner tube for centrifugally separating steam and water droplets moving up inside the peripheral space as they are guided by the helical fin. The outer tube has a steam outlet at an elevated position for discharging pure steam separated from water droplets, as well as an indentation above the helical fin for collecting water droplets which are centrifugally separated from steam. A discharge pipe is provided, leading to the indentation for discharging water collected in the indentation.
