High-temperature fans used in industrial thermal-processing furnaces basically provide a mechanical means to move atmosphere gases around inside the enclosed space at operating temperatures higher than about 1200[degrees]F (650[degrees]C). Fans used in heat-treating furnaces contribute to good uniformity of heating throughout the workload by convection and mix and circulate the special atmosphere around the work being processed. The working atmosphere in a carburizing furnace is continually flushed to remove water formed by combining with oxygen by adding natural gas, for example, to maintain carbon potential. This requires a dynamic atmosphere condition that is ...
