Abstract
A vaporization/pressurization module employs a porous member having a low thermal conductivity and a substantially uniform, small pore size. Liquid feed is introduced to the porous member and is heated, vaporized, and pressurized within and/or on a surface of the porous member to produce a vapor jet having a pressure higher than that of the liquid feed. A substantially vapor impermeable barrier facilitates accumulation and pressurization of the vapor, which is released from the module as a pressurized vapor jet from one or more restricted passages. The vaporization/pressurization module is especially useful for liquid fuel combustion applications.
Claims21
A vaporization/pressurization module comprising:
- a porous member composed of a material having a thermal conductivity of less than 10 W/m K and having a liquid feed surface, a liquid vaporization zone, a vapor release surface generally opposite the liquid feed surface, and sidewalls;
- a heat source in thermal communication with the porous member;
- and
- a substantially vapor impermeable barrier contacting the porous member sidewalls and in proximity to the porous member vapor release surface, the substantially vapor impermeable barrier having one or more vapor permeable locations permitting egress of pressurized vapor.
A vaporization/pressurization module Comprising:
- a porous member comprising a ceramic material having a substantially uniform small pore size, the porous member having a liquid feed surface, a liquid vaporization zone, a vapor release surface generally opposite the liquid feed surface, and sidewalls;
- a heat source in thermal communication with the porous member;
- and
- a substantially vapor impermeable barrier contacting the porous member sidewalls and in proximity to the porous member vapor release surface, the substantially vapor impermeable barrier having one or more vapor permeable locations permitting egress of pressurized vapor.
A vaporization/pressurization module comprising:
- a porous member comprising a material having a low thermal conductivity and an average pore size of from 0.5 to 5 microns, the porous member having a liquid feed surface, a liquid vaporization zone, a vapor release surface generally opposite the liquid feed surface, and sidewalls;
- a heat source in thermal communication with the porous member;
- and
- a substantially vapor impermeable barrier contacting the porous member sidewalls and in proximity to the porous member vapor release surface, the substantially vapor impermeable barrier having one or more vapor permeable locations permitting egress of pressurized vapor.
