  • Patent number: 6162046
    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.

  • Patent number: 5964585
    Abstract: An oil burner capable of ensuring normal combustion of quality-deteriorated kerosine. A burner body including a vaporization section is fed with fuel and air from a fuel pump and an air fan, respectively. A combustion control unit controls the fuel pump and air fan to control a combustion quantity in the burner body. The combustion control unit increases the combustion quantity to a combustion level sufficient to permit tar collected in the vaporization section to be burned at a predetermined time interval. Also, the combustion control unit keeps the combustion quantity increased to the combustion level for a predetermined period of time which permits tar collected in the burner body prior to an increase in combustion quantity to the combustion level to be substantially exhausted. This permits the combustion quantity to be intermittently increased, to thereby ensure substantial exhaustion of tar collected in the burner body.

  • Patent number: 5870525
    Abstract: 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.
