Abstract
A method of operating an evaporator is described. In evaporator feed water, a Taylor bubble is developed which has an outer surface including a thin film in contact with an inner surface of an outer wall of an evaporator tube. The Taylor bubble is heated as it rises within the evaporator tube so that liquid in the thin film transitions into vapor within the bubble.

A method of operating an evaporator, the method comprising:
- in evaporator feed water, developing a Taylor bubble having an outer surface including a thin film in contact with an inner surface of an outer wall of an evaporator tube;
- heating the Taylor bubble as it rises within the evaporator tube so that liquid in the thin film transitions into vapor within the bubble,
- providing the evaporator tube with an internal center rod to form an annular cylinder space within the evaporator tube so that an annular Taylor bubble is developed;
- and
- further providing the evaporator tube with an internal spiral wire wherein the internal spiral wire maintains the center rod in position within the evaporator tube.
