titanium food industry 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 actual heat transfer tube lot of money, the tube sheet, the baffle plate (baffle plate) along with the tube box. The shell is mainly cylindrical, and a conduit bundle is installed inside of, and the two ends belonging to the tube bundle are fixed around the tube plate.

There are two kinds of hot and cold liquids for heat exchange, some may be flowing inside the pipe, called the tube-side substance; the other is sweeping outside the tube, identified as the shell-side fluid.

In order to improve the heat transfer coefficient belonging to the fluid outside the tube, several baffles are usually installed while in the shell. The baffle can boost the velocity of the shell-side fluid, forcing the fluid to taste the tube bundle laterally multiple times as outlined by the prescribed distance, and enhancing their education of fluid turbulence.

There will be many variations on that shell and tube layout. Typically, the ends of every tube are connected to be able to plenums (sometimes called mineral water boxes) through holes within tubesheets. The tubes may be straight or bent while in the shape of a OUGH, called U-tubes.

In nuclear electrical power plants called pressurized h2o reactors, large heat exchangers called steam generators are two-phase, shell-and-tube warmth exchangers which typically possess U-tubes. They are used to boil water recycled from the surface condenser into steam to drive a turbine to produce power. Most shell-and-tube temperature exchangers are either YOU, 2, or 4 pass designs for the tube side. This refers to the amount of times the fluid from the tubes passes through the fluid while in the shell. In a one pass heat exchanger, the fluid gets into one end of every single tube and out other.

Surface condensers in power plants tend to be 1-pass straight-tube heat exchangers (see Exterior condenser for diagram). Two and four move designs are common because the fluid can enter and exit around the same side. This makes construction much easier.
