Abstract

See full text

A system for preheating batch materials in a glass melting furnace includes a preheater having an outlet through which fluid is exhausted and an inlet that receives fluids exhausted from the furnace and recirculated from the preheater outlet. In one embodiment, a cyclonic separator has an inlet in communication with the preheater outlet and an outlet in fluid communication with a fan. A controller controls the speed of the fan responsive to a drop in pressure between the separator inlet and outlet and a temperature at the separator outlet. In other embodiments, controllers control valves that (i) control the amount of fluids exhausted from the preheater that are delivered to a flue and recirculated to the preheater or (ii) control the amount of fluids diverted to charger for the furnace, in response to temperatures in a duct coupled to the preheater inlet.
