without baffles ship Shell and 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

This shell and tube heat exchanger consists of the shell, the particular heat transfer tube bundle, the tube sheet, the baffle plate (baffle plate) as well as the tube box. The shell is mainly cylindrical, and a pipe bundle is installed within, and the two ends of the tube bundle are fixed within the tube plate.

There are two varieties of hot and cold fluids for heat exchange, some may be flowing inside the television, called the tube-side h2o; the other is coursing outside the tube, known as the shell-side fluid.

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

There will be many variations on your shell and tube pattern. Typically, the ends of each tube are connected in order to plenums (sometimes called water boxes) through holes with tubesheets. The tubes may be straight or bent from the shape of a U, called U-tubes.

In nuclear electrical power plants called pressurized mineral water reactors, large heat exchangers identified as steam generators are two-phase, shell-and-tube heating exchangers which typically get U-tubes. They are accustomed to boil water recycled originating from a surface condenser into water to drive a turbine to produce power. Most shell-and-tube temperature exchangers are either 1, 2, or 4 pass designs within the tube side. This refers to the number of times the fluid while in the tubes passes through the fluid inside shell. In a solo pass heat exchanger, the fluid gets into one end of each one tube and out other.

Surface condensers in power plants tend to be 1-pass straight-tube heat exchangers (see Area condenser for diagram). Two and four pass designs are common since the fluid can enter and exit for the same side. This makes construction more simple.
