Abstract
A heat processing system in which a product is efficiently conveyed through a high temperature furnace and in which the product can be stored within a section of the furnace at a temperature less than the critical temperature to which product exposure must be limited. The furnace includes multiple sections each of a respective operating temperature, one of the sections being of high temperature to which a product can be exposed for only a limited time. A supply of product carriers is contained within the furnace onto which a product is supplied for transport forwardly through the furnace for unloading at an opposite end thereof, the carriers being returned rearwardly through the furnace back to a loading area. During an emergency mode of operation, loading of the product is discontinued and the product already within the furnace is transferred from the critical heat section to an adjacent section for storage at a lower temperature less than the high critical temperature.
