Abstract: The present invention relates to an apparatus for igniting and maintaining a simulated training fire for the purpose of teaching individuals to combat, contain and extinguish various classes, signatures and intensities of fires. More specifically, the present invention relates to a pilot flame ignition apparatus for use with a combustion tank, to provide a substantially inextinguishable pilot flame during and subsequent to the presence of a conflagration in the tank, the pilot flame being substantially impervious to the ingress of fire fighting agents into the tank.
