  • Patent number: 8549883
    Abstract: Systems and methods are provided for controlling temperature in a glass forehearth. In one implementation, a system includes at least one burner disposed in said forehearth, a manifold coupled to said burner, a combustion fuel supply coupled to said burner, a combustion air blower for delivering ambient air under pressure to said manifold, and a controller coupled to said burner for controlling operation of said burner. The system may include a temperature sensor operatively coupled downstream of the blower for providing to the controller a temperature signal indicative of temperature of air delivered to the manifold by the blower. The controller may be responsive to the temperature signal for controlling operation of the burner as a function of current temperature of air fed to the manifold. Operation of the burner may also be controlled as a function of an average air temperature over a preceding time duration.
