Webb13 dec. 2024 · Ans – In kettle type reboiler, external equipment is used i.e. pump to perform forces circulation where as in thermosyphon reboiler, thermosiphon effect is used to perform natural circulation. Wrapping Up This was the detailed information on what is reboiler and what are the types of reboiler.
WebbThe thermosiphon effect itself is based on a difference in density between coolant layers with varying temperatures. After being heated up in the engine, the coolant has a low density and thus rises; coolant that has cooled in the radiator sinks. These thermal forces thus make for continuous circulation. Webb5 nov. 2024 · In the heat pipes, the working fluid returns from the condenser to the evaporator due to capillary pumping effect while in the thermosyphon the working fluid returns exclusively by gravity because it has no capillary structure. A schematic diagram of the operating principle of heat pipes is presented in Figure 2 [ 11 ].
