Belt Furnace

The belt furnace is a continuous furnace concept that allows processing of small product directly on a belt. Mesh, cast link, flat wire and chain conveyors fall in this furnace category. The belts are supported in the furnace by a series of alloy or ceramic supports. Furnaces can be provided in electric, direct fired and indirect gas fired configurations to meet specific processing requirements. For special processes, retorts can be incorporated into the design. 

Systems have been provided with lengths exceeding 200 feet.
