ABSTRACT:
A portable heater comprising a double-wall vessel which forms a combustion chamber and encloses a suitable fuel. Air passages provide an airflow through the vessel for supporting combustion. Also included are endless conduits which entrap displaced fuel to prevent it from escaping from the heater through the air passages. Thus, fuel is prevented from escaping from the heater in all positions of the same in the event that the heater is dropped or otherwise upset. A set of cooling fins, encircling a fuel holder, cool the fuel to help maintain an even burn rate. The heater further includes an adjustable flame attenuator for selective heat control. At a low heat setting the invention may be used as a personal or close contact heater wherein an outer wall serves as a guard for preventing contact burns.
