Cyclone Gas-Fired Retort Pit Furnace Gas-fired pit furnaces with built-in retort available in single or two-stage nitriding systems. CYCLONE gas-fired pit furnaces are capable of temperatures up to 1250°F (1400°F optional). The furnaces have a separate heating/fan chamber that provides heat to the work chamber. The work chamber is heated when the supply gas is burned in the heating chamber then pressurized by a rapidly circulating fan. Pressure above, and suction below, force the heated gases through the around the retort at high velocity with minimal temperature drop. Excess volume is forced out through a flue after passing through the work chamber. A “suspended” fan shroud mates with either the basket or baffle to provide a closed path of circulation when the cover is closed. Atmosphere leaves the fan and travels downward through annualar clearance between retort and basket or shroud to below the load support, then upward through the work before again entering the fan inlet. The arrangement includes a water-cooled lower bearing/atmosphere seal. The retort with sealed cover and circulating fan is provided. Loading the Cyclone pit furnace is virtually foolproof. Because the fan and heating elements are separate from the load chamber, damage from accidental contact is eliminated. The entire work chamber is metal-lined for maximum durability. The Cyclone is designed for convenient maintenance. The fan motor is externally accessible for easy service and replacement. Features
