THERMALLY-ACTUATED GAS VALVE WITH CERAMIC HEATER
A thermally-actuatable gas valve assembly comprising a ceramic heater is shown and described. The gas valve assembly comprises a housing with a gas inlet and a gas outlet. A bimetal thermal actuator has a valve plug that removably seals the gas outlet from the interior of the housing. The ceramic heater is energizable to cause the thermal actuator to deflect which unseats the valve plug from the gas outlet, thereby placing the gas outlet in fluid communication with the gas inlet and the interior of the housing. A gas heating system is also shown and described in which the gas valve assembly selectively supplies cooking gas to a silicon nitride ceramic igniter. The igniter and the heater are in series such that when a source of alternating current is applied across the igniter and the heater, the igniter reaches the autoignition temperature of the combustion gas before the valve assembly opens
