Item Description
– There can be many variations on the shell and tube design. Typically, the ends of each tube are connected to plenums (sometimes called water boxes) through holes in tube sheets. The tubes may be straight or bent in the shape of a U, called U-tubes.
– A U – type heat exchanger is a class of heat exchanger. It is the most common type of heat exchanger in oil refineries and other large chemical processes. As its name implies, this type of heat exchanger consists of a shell (a large vessel) with a bundle of tubes inside it.
– . They are used to boil water recycled from a steam turbine condenser into steam to drive the turbine to produce power.
– In nuclear power plants with pressurized water reactors, large heat exchangers called steam generators are two-phase,
Technical Specifications
CONSTRUCTION OF U – TUBE HEAT EXCHANGER:
– Heat-exchanger system consisting of a bundle of U tubes (hairpin tubes) surrounded by a shell (outer vessel), one fluid flows through the tubes, and the other fluid flows through the shell, around tubes. This is the cheapest of all removable bundle designs, but is generally slightly more expensive than a fixed tube sheet design at low pressures.
– However, it permits unlimited thermal expansion, allows the bundle to be removed to clean the outside of the tubes, has the tightest bundle to shell clearances and is the simplest design. The fluids can be single or two phase and can flow in a parallel or a cross/counter flow arrangement.
– `Two fluids, of different starting temperatures, flow through the heat exchanger. One flows through the tubes (the tube side) and the other flows outside the tubes but inside the shell (the shell side).
