ABSTRACT:
Asphalt heating kettle with improved temperature control to prevent overheating, and with improved gas fuel pilot light to prevent pilot blowout. The temperature sensor for the kettle is housed in an apertured tube in direct heat transfer contact with a burner flue within the kettle, so that the temperature both of liquid asphalt and of the flue itself is sensed to prevent an overheat condition. The pilot burner is located behind the main burner, upstream of the high-velocity flame from the main burner, so as to be unaffected by the blast or shock wave of main burner ignition.
