Claims
- 1. A thermosyphonic heat recovery unit for thermosyphonic heat transfer of heat from a hotter first fluid to a cooler second fluid, comprising in combination:
- a heat exchanger including a first fluid conduit and a second fluid conduit connected in a heat exchanging relationship with one another;
- means for connecting a pressurized source of the hotter first fluid in fluid communication with said first conduit enabling the hotter first fluid to flow through said first conduit;
- means for connecting said second conduit in fluid communication with a non-pressurized source of the cooler second fluid;
- said source of the second fluid comprising a tank in which the second fluid is stored;
- the input and the output of said second conduit being connected in fluid communication with the lower and the upper regions, respectively, of said tank; and
- said tank including a pressurized cold fluid input and hot fluid output and further comprising a mixing valve interconnected in fluid communication between said cold fluid input and said hot fluid output;
- whereby the second fluid thermosyphonically flows through said second conduit as the first fluid flows through said first conduit.
- 2. The heat recovery unit as set forth in claim 1, wherein said heat exchanger comprises a tube and tube heat exchanger which is coiled about the circumference of said tank.
- 3. The heat recovery unit as set forth in claim 1, further including an insulation blanket positioned about said tank and said tube-in-tube heat exchanger.
