ABSTRACT:
This is a catalytic heater which is so inexpensive that it may be used as a disposable heater. It has a lower container section or fuel cartridge and wick for the fuel and any other liquid that may be present for dispensing. It is used together with an upper chimney container section. Alternately, only the fuel cartridge may be disposed of, and a new fuel cartridge may be mated with the previously used upper chimney section. A catalytic impregnated stainless steel member is reuseable along with a snuffer to be secured to the upper chimney section. The catalytic impregnated member is stainless steel, of approximately 0.0037 gauge, and may be either a foraminated plate or a wire mesh screen woven approximately 80 strands to the inch. A filter made of activated charcoal or any other comparable filtering material may also be provided over the fuel supply.
In addition, the fuel compartment may be divided by vertical partitions into two or three compartments, particularly for use with liquids, such as insect repellants and other chemicals that are not miscible with liquid fuel.
A fuel material with an upstanding wick is provided in the lower container section, and a snuffer tube is located in the upper chimney section for snuffing out the flame on the wick and thus permitting the catalytic heating action to continue. An insulating coating is provided on both sections to retain the heat, and to make it possible to carry the heater without it being too hot for comfort.
