ABSTRACT:
A furnace for thermally processing product includes one or more eductors. The eductor provides for increased circulation of atmosphere within the furnace for heat transfer or outgassing purposes. The eductor may be used to introduce clean gas to a product which outgasses volatiles to enhance the outgassing process by lowering the partial pressure of the volatile across the product as it is being heated. The eductor is also used to enhance heating or cooling of a product. Additionally, the eductor may be used to reduce or eliminate air stagnation areas within the furnace. The eductor may be located entirely within the furnace to recirculate the atmosphere of the furnace. Alternatively, the eductor may be located outside the furnace housing such that the eductor entrains gas from ports attached to the furnace and then reintroduces the gas into the furnace after the gas is cleaned, heated or cooled.
