MANTRA Glassmaking Forehearth Control

One of the most difficult furnace control problems are the glass manufacturing forehearth furnaces. Molten glass is the temperature range between 2,300 and 2,800° F is distributed in the forehearth furnace, which brings the temperature of the molten glass to a uniform level prior to the next glass manufacturing step. Controlling glass furnace temperatures, levels and forehearth temperatures is a difficult task. Long temperature response time causes conventional controllers to cycle on set-point changes. Changes in production rate affect process gain and time lag for the temperature control loops resulting in nonlinear dynamics.
