What types of heat exchangers are applicable to GBl51? Answer: Fixed tube sheet type, floating head type, U-tube type, packing box type
Fixed tube sheet type, floating head type, U-tube type, packing box type
Fixed tube sheet type, floating head type, U-tube type, packing box type
Fixed tube sheet type, floating head type, U-tube type, packing box type
Shell-and-tube heat exchangers come in various types such as fixed-head type, floating-head type, U-tube type, and stuffing box type exchangers (reactor-type reboilers). Mechanical designs such as baffle-type heat exchangers and coil-type heat exchangers that do not fall into these categories are also designed in accordance with this standard.

I. Surface-type heat exchangers: In surface-type heat exchangers, two fluids with different temperatures flow in spaces separated by a wall. Heat transfer occurs between the two fluids through heat conduction through the wall and convection of the fluids at the wall surface. Surface-type heat exchangers include shell-and-tube, double-pipe, and other types of heat exchangers. II. Regenerative Heat Exchangers: Regenerative heat exchangers utilize a regenerator made of solid material; the hot medium first passes through this solid material to reach a certain temperature, after which the cold medium passes through it as well, thereby enabling heat transfer to take place. III. Fluid-connected indirect heat exchangers: Fluid-connected indirect heat exchangers are those in which two surface heat exchangers are connected by a heat transfer fluid that circulates within them; this heat transfer fluid circulates between the high-temperature fluid and the low-temperature fluid. IV. Direct contact heat exchangers A direct contact heat exchanger is a device in which two fluids come into direct contact to exchange heat.
