摘要： An oxidation oven for use in the production of carbon fibers from a polyacrylonitrile precursor fiber. The oven has an oven chamber formed by sides and ends. At least one of the ends has a first opening and a second opening. The product passes through the openings for treatment in the oven chamber. The oven is also provided with a first nozzle adjacent the first opening and a second nozzle adjacent the second opening. Each nozzle is effective for discharging air from an air flow pathway into the oven chamber and forming an air curtain at the opening to which it is adjacent. An air bar defines the air flow pathway.
