WebFluid return is normally accomplished by gravity. The constant circulation of evaporating and condensing of the working fluid is the principle of heat pipes heat transfer. Heat pipes can transfer heat with minimal temperature difference between one end and the other. WebHPNC boilers are designed as a closed-loop system (a so-called thermo syphon system) in which gravity drives the circulation process. Two concentric coils are used to generate the steam. The inner coil forms the furnace and the outer coil provides convective heat transfer through the second and third gas passes.
