ABSTRACT:
A heat pipe recuperator for recovering heat from flue gas stacks is disclosed. The recuperator consists of a toroidal shell forming a fluid heating chamber having inlet and outlet fluid circulating ports. A plurality of heat pipes are mounted within the chamber and are attached to the inner wall of the shell such that the condensor sides of the pipe reside within the shell and the evaporator sides extend outside the shell into the center of the toroid. The recuperator is positioned in a flue gas stack wherein the hot flue gas stream contacts the heat pipes which transfer heat into the fluid heating chamber. Fluid, gas or liquid, is passed through the chamber resulting in a rise in temperature of the fluid.
