The shell and tube heat exchanger is composed of the shell, the heat transfer tube bundle, the tube sheet, the baffle plate (baffle plate) and the tube box. The shell is mostly cylindrical, and a tube bundle is installed inside, and the two ends of the tube bundle are fixed on the tube plate.
There are two kinds of hot and cold fluids for heat exchange, one is flowing inside the tube, called the tube-side fluid; the other is flowing outside the tube, called the shell-side fluid.
In order to improve the heat transfer coefficient of the fluid outside the tube, several baffles are usually installed in the shell. The baffle can increase the velocity of the shell-side fluid, forcing the fluid to pass through the tube bundle laterally multiple times according to the prescribed distance, and enhancing the degree of fluid turbulence.
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 tubesheets. The tubes may be straight or bent in the shape of a U, called U-tubes.
In nuclear power plants called pressurized water reactors, large heat exchangers called steam generators are two-phase, shell-and-tube heat exchangers which typically have U-tubes. They are used to boil water recycled from a surface condenser into steam to drive a turbine to produce power. Most shell-and-tube heat exchangers are either 1, 2, or 4 pass designs on the tube side. This refers to the number of times the fluid in the tubes passes through the fluid in the shell. In a single pass heat exchanger, the fluid goes in one end of each tube and out the other.
Surface condensers in power plants are often 1-pass straight-tube heat exchangers (see Surface condenser for diagram). Two and four pass designs are common because the fluid can enter and exit on the same side. This makes construction much simpler.

That shell and tube heat exchanger is composed of the shell, that heat transfer tube pile of cash, the tube sheet, the baffle plate (baffle plate) along with the tube box. The shell is mostly cylindrical, and a esophagus bundle is installed inside, and the two ends of the tube bundle are fixed about the tube plate.
There are two sorts of hot and cold essential liquids for heat exchange, is flowing inside the esophagus, called the tube-side smooth; the other is sweeping outside the tube, labeled the shell-side fluid.
As a way to improve the heat transfer coefficient in the fluid outside the esophagus, several baffles are usually installed inside the shell. The baffle can increase the velocity of the shell-side smooth, forcing the fluid to taste the tube bundle laterally multiple times according to the prescribed distance, and enhancing their education of fluid turbulence.
There will be many variations on this shell and tube design and style. Typically, the ends of each one tube are connected for you to plenums (sometimes called waters boxes) through holes throughout tubesheets. The tubes can be straight or bent inside shape of a U, called U-tubes.
In nuclear energy plants called pressurized h2o reactors, large heat exchangers referred to as steam generators are two-phase, shell-and-tube temperature exchangers which typically own U-tubes. They are helpful to boil water recycled at a surface condenser into heavy steam to drive a turbine to produce power. Most shell-and-tube warmth exchangers are either ONE, 2, or 4 pass designs for the tube side. This refers to the amount of times the fluid inside the tubes passes through the fluid inside the shell. In a single pass heat exchanger, the fluid gets into one end of each and every tube and out other.
Surface condensers in power plants can be 1-pass straight-tube heat exchangers (see Area condenser for diagram). Two and four go designs are common since the fluid can enter and exit about the same side. This makes construction incredibly easier.
