A portable catalytic combustion heater, wherein fuel vapor (11) and air (10) are supplied to a catalyst (6) which promotes the flameless combustion of fuel and releases that. The fuel is supplied as a liquid, passes through a selectively permeable membrane (8) such as fuel vapor exits the membrane and is fed to the catalyst (6). Additional features include porous supports and means of enhancing and diminishing the catalytic rate of combustion and controlling the heat output.

The present invention is a method of delivering vaporized alcohol fuel through a thermally conductive porous nozzle to a catalytic burner with a plasma cavity and a surrounding porous catalytic cavity with fuel vapor and air supplied separately and inter diffusing into each other from different routes to the catalyst to achieve an efficient, steady, and complete combustion of the hydrogen bearing fuels. This heating system with passive auto thermostatic behavior, coupled to thermopiles, heat pipes and fluid heating systems may provide useful heat and electricity to applications of floors, roadways, runways, electronics, refrigerators, machinery, automobiles, structures, and fuel cells.

This invention discloses a portable catalytic combustion heater. Fuel vapor and air are supplied to a catalyst which promotes the flameless combustion of the fuel, releasing heat. The fuel is supplied as a liquid, passes through a selectively permeable membrane such that fuel vapor exits the membrane and is fed to the catalyst. Additional features such as porous supports and means of enhancing and diminishing the catalytic rate of combustion and controlling the heat output are also shown. This invention can be used to heat apparel, blankets, food, dwellings, containers, machinery, insect attractants, humidifiers, and perfume generators.

A device that can be used for dispersing or dispensing a liquid is provided that comprises a container, a nozzle device, a secondary wick, and a control device in which the container comprises, an open end and a liquid; the nozzle comprises a primary wick, a first end being in fluid communication with the liquid, and a second end extending through the open end of the container and having an opening; the aperture has extended therethrough the primary wick; the secondary wick extends into proximity with the primary wick; and the secondary wick is securely connected to a control device, which controls the distance between the primary wick and the secondary wick.
摘要:
The system has a catalytic combustion burner which comprises on its upper part a peripheral zone supporting a catalyst and a central zone without a catalyst creating a vaporisation zone. The system further comprises a sleeve made of porous material comprising a cavity substantially axial designed to tightly hold a wick purposed to carry a combustible composition to the burner. The sleeve is placed in line with the lower part of the burner so that the combustible composition can move from the pores of the upper part of the sleeve towards the pores of the lower part of the burner.

The invention relates to a method of combating insects and parasites, and in particular acarids, the method comprising a step of diffusing a composition that includes permethrin in a solvent. The method is such that a composition is diffused in a chamber to be treated, the composition comprising permethrin and tetramethrin in a solvent, and it is diffused in such a manner that said solvent is entirely in the gaseous state.

A field-ready oven has reinforced telescoped side walls that extend and hold a base, shelf, tray support and cover spaced apart. A low air intake and a semipermeable membrane deliver air and vapor fuel to catalyst pads on the shelf. Radiant heat from exothermic reaction is diffused over a bottom of a tray. Hot gas circulates around the diffuser and tray with a chimney effect before exhausting. A lid on the cover lifts for access to the tray. A fuel container in the oven forces fuel through a capillary restriction to limit fuel flow. A spring in the container is released to start fuel flow.
摘要:
Fuels compositions based on exempt compounds are provided. These fuels are useful in catalytic burner systems that can be used to disperse fragrances, insecticides, insect repellants (e.g., citronella), aromatherapy compounds, medicinal compounds, deodorizing compounds, disinfectant compositions, fungicides and herbicides.
