Evaporator Article about Evaporator by The Free …

In thermal power engineering, the evaporator is used to produce a distillate that compensates for losses of condensate in steam power plants. A tube vertical evaporator is usually heated by the steam coming from the turbine and passing through the space between the tubes. The evaporating water, which is softened in advance, passes within the tubes.
