Method for controlling temperature in a forehearth

摘要

Abstract of the Disclosure Systems and methods are provided for controlling temperature in a glass forehearth (11). In one implementation, a system includes at least one burner (24) disposed in the forehearth, a manifold (22) coupled to the burner, a combustion fuel supply (26) coupled to the burner, a combustion air blower (20) for delivering ambient air under pressure to the manifold, and a controller (30) coupled to the burner for controlling operation of the burner. The system may include a temperature sensor (36) 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. Fig. 6 -9 --- 60 62 7 -3 0 10 20 30 40 150 60 70 80 90 100 Controller Output
