Abstract
A system for preheating batch materials includes a preheater, a charger, a first temperature sensor, a second temperature sensor, a valve, and a charger temperature controller. A first recirculation duct provides exhaust fluids from the charger to a second recirculation duct coupled to an inlet of the preheater. The first temperature sensor is configured to generate a first temperature signal indicative of a first temperature of fluids within the second recirculation duct and the second temperature sensor is configured to generate a second temperature signal indicative of a second temperature of the fluids within the second recirculation duct upstream of where the first temperature is obtained. The valve is configured to control an amount of fluid in the second recirculation duct that is diverted to the charger and the charger temperature controller is configured to control the valve responsive to the first and second temperatures.
