ABSTRACT:
An elongated casing forming an air cooled combustion chamber includes a venturi type jet nozzle at one end and an ignition system spark plug at its opposite end in axial alignment with the nozzle bore. The spark plug includes a first electrode separated from a second electrode by an annular space. A gas having an oxygen content in excess of that of natural air is introduced to the annular space to improve ignition and internal burner start up. Liquid fuel flow is introduced into the region of extended spark within the combustion chamber and downstream of the ends of the first and second electrodes. Compressed air, after initial cooling of the combustion chamber wall and nozzle, enters the end of the combustion chamber housing the spark plug to create with the fuel a combustible mixture. Some of the compressed air is fed to the annular space between first and second electrodes to maintain the extended spark and improved ignition of the fuel/air mixture.
