Abstract:
1. A water vaporizer comprising: a first flow path connected to a water inlet; a second flow path for receiving superheated water vapor from the first flow path and being connected to a vapor outlet to exhaust the superheated water vapor; a third flow path extending between an exhaust inlet and an exhaust outlet and being oriented to transfer heat from an exhaust flow to the superheated water vapor; a first convoluted fin positioned along the second flow path; and a second convoluted fin positioned along the second flow path adjacent to and separated from the first fin to define a gap extending between the first and second fins along a length of the first fin in a direction substantially parallel to the exhaust flow along the third flow path, wherein the gap is located in the second flow path.
