floating head food industry 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

That shell and tube heat exchanger is composed of the shell, the heat transfer tube lot of money, the tube sheet, the baffle plate (baffle plate) along with the tube box. The shell is certainly caused by cylindrical, and a television bundle is installed interior, and the two ends in the tube bundle are fixed within the tube plate.

There are two different hot and cold fluids for heat exchange, is flowing inside the pipe, called the tube-side fluid; the other is sweeping outside the tube, identified as the shell-side fluid.

So that you can improve the heat transfer coefficient of the fluid outside the tv, several baffles are usually installed in the shell. The baffle can enhance the velocity of the shell-side substance, forcing the fluid to taste the tube bundle laterally multiple times in accordance with the prescribed distance, and enhancing the degree of fluid turbulence.

There are many variations on that shell and tube design. Typically, the ends of every tube are connected in order to plenums (sometimes called drinking water boxes) through holes around tubesheets. The tubes could be straight or bent in the shape of a U, called U-tubes.

In nuclear electric power plants called pressurized water reactors, large heat exchangers known as steam generators are two-phase, shell-and-tube temperature exchangers which typically include U-tubes. They are accustomed to boil water recycled from a surface condenser into water to drive a turbine to form power. Most shell-and-tube heating exchangers are either ONE, 2, or 4 pass designs on the tube side. This refers to may be times the fluid from the tubes passes through the fluid inside the shell. In a solitary pass heat exchanger, the fluid goes in one end of each one tube and out additional.

Surface condensers in power plants will often be 1-pass straight-tube heat exchangers (see Exterior condenser for diagram). Two and four complete designs are common as the fluid can enter and exit to the same side. This makes construction incredibly easier.
