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.

This shell and tube heat exchanger is composed of the shell, this heat transfer tube combine, the tube sheet, the baffle plate (baffle plate) along with the tube box. The shell is mostly cylindrical, and a conduit bundle is installed inside of, and the two ends with the tube bundle are fixed on the tube plate.
There are two forms of hot and cold body fluids for heat exchange, you are flowing inside the conduit, called the tube-side fluid; the other is going outside the tube, called the shell-side fluid.
So that they can improve the heat transfer coefficient from the fluid outside the tube, several baffles are usually installed in the shell. The baffle can add to the velocity of the shell-side smooth, forcing the fluid to go through the tube bundle laterally multiple times in accordance with the prescribed distance, and enhancing their education of fluid turbulence.
There will be many variations on the actual shell and tube pattern. Typically, the ends of every tube are connected to help plenums (sometimes called h2o boxes) through holes inside tubesheets. The tubes can be straight or bent from the shape of a OUGH, called U-tubes.
In nuclear strength plants called pressurized waters reactors, large heat exchangers named steam generators are two-phase, shell-and-tube heating exchangers which typically have got U-tubes. They are helpful to boil water recycled from your surface condenser into water to drive a turbine to offer power. Most shell-and-tube warm exchangers are either 1, 2, or 4 pass designs on the tube side. This refers to how many times the fluid while in the tubes passes through the fluid while in the shell. In a solo pass heat exchanger, the fluid goes in one end of every tube and out the opposite.
Surface condensers in power plants are often 1-pass straight-tube heat exchangers (see Surface area condenser for diagram). Two and four go away designs are common because fluid can enter and exit about the same side. This makes construction incredibly easier.
