Tube Bundle Heat Exchangers
Tube Bundle Heat Exchangers
JC Equipments offers a range of Tube Bundle Heat Exchangers. In that part of nuclear power plants called pressurised water reactors, large heat exchangers called steam generators are used. These 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 of 1-, 2-, or 4-pass design 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. In offshore industries, water makers are made up of U-tube heat exchangers, to maintain the lower pressure drop in high tube length. A tube bundle heat exchanger with baffles is disclosed wherein a tube bundle is housed within an inner casing which is acted upon from both the inside and the outside by a heating medium. A multiple tube bundle heat exchanger includes axially opposite tube plates, a housing, and a plurality of tube bundles disposed between the tube plates. Each of the tube bundles is an independent tube bundle sub-assembly forming an integral unit having at least one heat exchanger tube with two axial tube ends.
