stainless steel ship Shell Tube Heat Exchanger

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.

Product picture

The particular shell and tube heat exchanger consists of the shell, that heat transfer tube lot of money, the tube sheet, the baffle plate (baffle plate) as well as the tube box. The shell is mostly cylindrical, and a tube bundle is installed interior, and the two ends on the tube bundle are fixed on the tube plate.

There are two varieties of hot and cold essential fluids for heat exchange, an example may be flowing inside the tube, called the tube-side substance; the other is going outside the tube, known as the shell-side fluid.

So that they can improve the heat transfer coefficient of the fluid outside the conduit, several baffles are usually installed in the shell. The baffle can add to the velocity of the shell-side fluid, forcing the fluid to move across the tube bundle laterally multiple times in line with the prescribed distance, and enhancing their education of fluid turbulence.

There is many variations on your shell and tube pattern. Typically, the ends of each one tube are connected for you to plenums (sometimes called normal water boxes) through holes throughout tubesheets. The tubes could be straight or bent inside the shape of a U, called U-tubes.

In nuclear power plants called pressurized waters reactors, large heat exchangers known as steam generators are two-phase, shell-and-tube warm exchangers which typically have U-tubes. They are utilized to boil water recycled from your surface condenser into heavy steam to drive a turbine to offer power. Most shell-and-tube temperature exchangers are either YOU, 2, or 4 pass designs within the tube side. This refers to the number of times the fluid within the tubes passes through the fluid from the shell. In a solitary pass heat exchanger, the fluid goes in one end of each one tube and out the opposite.

Surface condensers in power plants are sometimes 1-pass straight-tube heat exchangers (see Floor condenser for diagram). Two and four go away designs are common because of the fluid can enter and exit within the same side. This makes construction easier.
