ABSTRACT:
The gas flow and ignition of gas in a gas fired clothes dryer is controlled by coupling a soft ferrite material radiatively to an igniter element and non-radiatively to a heat sink. The temperature assumed by the ferrite material is above its curie point when the igniter element is hot enough to ignite the gas and below its curie temperature when the igniter is insufficient to ignite the gas. The change in the permeability of the ferrite material moves a magnet which controls the heating of the igniter element and the flow of gas.
