Abstract: A device for dispensing a volatile substance includes a gas-fueled, portable heat source. The device includes a catalyst support structure to flamelessly combust liquid or gaseous fuel and thereby provide a lower temperature heat source than a heat source that combusts fuel via flame. The fuel is ignited inside the catalytic support structure by a spark electrode. A spark jumps from the electrode to an interior surface of the structure and ignites the fuel inside the structure, causing a flame to propagate. The flame heats the catalytic structure to an activation temperature, after which the fuel is combusted flamelessly on the surface of the catalytic structure. The device includes a heating plate for heating the volatile substance and for receiving heat from the catalytic structure. A heat box substantially surrounds the catalytic structure and heating plate. The heat box has a window through which volatile substances released from the heating plate may escape.
