A fuel burner in which the flame supporting portion is a ceramic nozzle tube attached to an electrically conductive supply tube which supplies fuel through one end of the ceramic tube to support a flame emitting from the other end of the ceramic tube. The ceramic tube has first and second transverse electrodes projecting generally along diameters of the ceramic tube with the electrodes at approximately right angles to each other and spaced axially in the tube from each other to provide a spark gap therebetween. One of the electrodes extends axially on the outer surface of the ceramic tube to a hook end which projects inwardly through a bore in the fuel supply tube for securing the ceramic tube to the fuel supply tube. The fuel supply tube is grounded to ground the electrode. The other electrode is connected to a high voltage source to produce a spark across the gap for igniting a fuel-air mixture entering the ceramic tube from the fuel supply tube. An incinerating toilet utilizing the ceramic head burner is also provided.
