WATER HEATER WITH CROSS-SECTIONALLY ELONGATED RAW FUEL JET PILOT ORIFICE |
摘要 |
A radiant gas burner within the combustion chamber of a water heater has a pilot flame created using a cross-sectionally elongated raw fuel jet that impinges on an interior surface portion of a flame holding outer burner wall portion, representatively of a metal wire mesh material, and is mixed within the burn er with combustion air delivered thereto from outside the combustion chamber. The resulting fuel/air mixture passes outwardly through the impinged upon mesh wall portion, which functions as a pilot flame stabilizing structure, and is ignited to form a pilot flame on the exterior of the burner body. A thermocouple portion of a clogging detection system senses a change in the pilot flame shape caused by particulate clogging of the metal mesh material and responsively terminates further gas supply to the water heater.
