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.

Your shell and tube heat exchanger consists of the shell, the particular heat transfer tube pack, the tube sheet, the baffle plate (baffle plate) plus the tube box. The shell is certainly caused by cylindrical, and a television bundle is installed on the inside, and the two ends of the tube bundle are fixed for the tube plate.
There are two sorts of hot and cold fluids for heat exchange, one is flowing inside the television, called the tube-side substance; the other is flowing outside the tube, identified as the shell-side fluid.
To be able to improve the heat transfer coefficient belonging to the fluid outside the conduit, several baffles are usually installed inside shell. The baffle can boost the velocity of the shell-side liquid, forcing the fluid to suffer the tube bundle laterally multiple times in line with the prescribed distance, and enhancing the degree of fluid turbulence.
There might be many variations on the actual shell and tube style and design. Typically, the ends of every tube are connected that will plenums (sometimes called drinking water boxes) through holes around 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 normal water reactors, large heat exchangers identified as steam generators are two-phase, shell-and-tube high temperature exchangers which typically get U-tubes. They are helpful to boil water recycled coming from a surface condenser into water to drive a turbine to form power. Most shell-and-tube temperature exchangers are either YOU, 2, or 4 pass designs for the tube side. This refers to the quantity of times the fluid inside tubes passes through the fluid inside the shell. In a solo pass heat exchanger, the fluid gets into one end of each tube and out one other.
Surface condensers in power plants are sometimes 1-pass straight-tube heat exchangers (see Exterior condenser for diagram). Two and four pass designs are common because of the fluid can enter and exit within the same side. This makes construction incredibly easier.
