Patent number: 6585509Abstract: A vaporization module is provided that includes a capillary member to convert non-pressurized liquid to pressurized vapor. The pressure is sustained by capillary pressure of the liquid in the capillary member. The capillary member has low thermal conductivity and small-sized pores that permits liquid to travel by capillary action toward the vaporization zone. Often, the pores of the capillary member are substantially uniform in size. The capillary member may comprise ceramic material. The module also includes an orifice plate that has one or more orifices to permit release of pressurized vapor, e.g. as a pressurized vapor jet. The orifice plate is associated with a sealing member to form an at least partial enclosure of the module so that vapor may accumulate and pressure may be increased within the module. In addition, other aspects of the present invention relating to the vaporization and pressurization of liquid are described.Type: GrantFiled: February 19, 2002Date of Patent: July 1, 2003Assignee: Allports LLC InternationalInventors: Thomas M.

Patent number: 6347936Abstract: 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.Type: GrantFiled: September 5, 2000Date of Patent: February 19, 2002Assignee: Allports LLC InternationalInventors: Thomas M.

Patent number: 5870525Abstract: The invention is an improved boiler for generating vapor at low pressure from liquid in reservoirs that are not pressurized. Liquid from a reservoir is fed through a supply wick by capillary action to a boiler wick in which the liquid is heated and boiled to a vapor. The heat for vaporization is transmitted by a porous hot seat which sits atop and is in contact with the boiler wick. The boiler wick and hot seat are contained within an insulating cylindrical shroud, which forms a tight seal with the edges of the boiler wick. If the liquid to be vaporized is a fuel for a burner, then combustion heat can be used to supply the heat to the boiler. A resistive heat source can also be used to heat the hot seat and boiler wick.Type: GrantFiled: October 7, 1997Date of Patent: February 9, 1999Assignee: Allports LLC InternationalInventor: Niels Owen Young

Patent number: 4465458Abstract: A liquid fuel combustion apparatus for evaporating and vaporizing kerosene, gas oil or like liquid fuel by heating, admixing air with the vaporized fuel in a specified ratio and burning the resulting gaseous mixture in a combustion unit. The vaporizer for the liquid fuel comprises a liquid fuel drawing-up member (15) made of a heat-resistant porous body (8) or heat-resistant inorganic fiber fabric (9) for drawing up the liquid fuel, and a heat generating member (6) including coating layers (22, 23) of heat-resistant metal, heat-resistant alloy or heat-resistant metallic oxide for giving heat to the drawing-up member. To prevent formation of tar-like substances, a catalyst is preferably deposited on the surface of the drawing-up member and/or on the surface of the heat generating member. Further preferably, the outer periphery of the heat generating member (6) is in contact with the drawing-up member (5).Type: GrantFiled: June 11, 1982Date of Patent: August 14, 1984Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Atsushi Nishino, Kazunori Sonetaka, Yasuhiro Takeuchi

Patent number: 4365952Abstract: A liquid fuel burner for burning liquid fuel in the form of a gaseous mixture with air. The liquid fuel burner has a porous member provided at least with a fuel receiving section for receiving the liquid fuel supplied to the burner and a fuel evaporation section from which the liquid fuel is evaporated. An air supplying device is provided for forcibly supplying air to the fuel evaporation section. The rate of air supply is varied by means of a damper or like means. Heating means are provided for maintaining the fuel evaporation section at a substantially constant temperature. The rate of burning is varied while maintaining the air-fuel ratio of the mixture substantially constant, because the rate of evaporation of the fuel is almost in proportion to the rate of supply of air to the fuel evaporation section. The heating means facilitates the evaporation of the fuel and permits a rapid rise and stabilization of burning after ignition.Type: GrantFiled: March 18, 1980Date of Patent: December 28, 1982Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yoshimi Ohmukai, Toshiro Ogino, Kinichi Adachi, Hisanori Nishiguchi
