An apparatus for fluid fuel ignition which consists essentially of an igniter which reaches a temperature above the ignition temperature of the fuel when sufficient electricity from an electrical source passes through the igniter and which igniter remains continuously at a temperature above the ignition temperature of the fuel while the fuel passes through a fuel injection means proximate to the igniter. A thermal delay relay which activates a valve, which permits fuel to pass through the fuel injection means proximate the igniter, is responsive to current flow through the igniter after the igniter has reached ignition temperature. The apparatus requires no mechanical moving parts other than a thermostat, one electrical relay and a fuel valve responsive to an electrical signal. Only two sets of electrical contacts are required in the entire apparatus including the thermostat and internal relay contacts. The apparatus may be conveniently designed to operate at either low or high voltage. A low voltage thermostatic control may optionally be used in conjunction with a high voltage ignition which requires only one additional relay. |
