<p>An ignitor 94 comprising a low voltage incandescent resistance heater 96 is utilized to ignite a liquid oil/air mixture in an oil-fired combustor 30. The resistance heater 94 is located within a combustion chamber 36 in a zone where a combustible mixture of oil and air is present but remote from the direct spray of liquid fuel oil, thus the ignitor 94 is protected from becoming fouled by contact with the oil. When energized, the heater element 96 reaches a temperature of about 1200F DEG -2500 DEG F and creates a plume of hot gas which causes ignition. In the preferred form, a commercially available glow plug is used, and is energized by a low voltage of about 12 volts and draws about 30-35 amperes.</p> |
