There are two primary types of condensers that can be used in a power plant: (a) Direct contact (b) Surface Direct contact condensers condense the turbine exhaust steam by mixing it directly with cooling water. The older type Barometric and Jet type condensers operate on similar principles. Steam surface condensers are the most commonly used...

The basic principle is that the constant vaporization of a portion of the liquid in the reboiler produces a two-phase mixture with an average density lower than the liquid being fed to the reboiler. The heavier column of liquid on the reboiler inlet side then pushes the lighter material out of the reboiler causing circulation. […]

The amount and type of dissolved and/or suspended solids in the stream which may deposit on the tube wall.   The susceptibility to thermal decomposition which will form a thermal barrier on the tube walls.   The velocity of the fluid.   The temperature of the fluid   The fouling resistance specified for a particular […]

Typical overall heat transfer coefficients are given below. These “typical” heat transfer coefficients can be used to estimate the performance of a heat exchanger. Typical heat transfer coefficients are normally published as a range of an “all-in” numbers which includes the inside and outside heat transfer coefficients, the...
