MURRAY HILL, N.J. and NEW PROVIDENCE, N.J., Oct. 20, 2015 /PRNewswire/ -- Patented CARBOJET® gas injection technology that can improve the productivity of heat treatment furnaces without the use of circulation fans will be introduced by Linde LLC for the first time at Heat Treat 2015, booth #248.
The gas mixing technology is ideal for upgrading a variety of furnaces including roller hearth, pusher, rotary-retort and pit furnaces. Ultra-high-speed injection of a gas or gas mixture through special CARBOJET lances improves gas and atmosphere flows and circulation. This includes both the better mixing of the injected gases with the furnace atmosphere, and better movement of gas flows within the furnace.
"CARBOJET® technology has already proven successful in many heat treatment operations in Europe because rapid gas injection and homogenous mixing are hallmarks of process efficiency and product quality."
– Grzegorz Moroz, program manager, heat treatment and atmospheres, Linde LLC
Specific advantages will depend on the type of heat treatment furnace. In continuous furnaces, for example, CARBOJET gas-injection technology offers a variety of benefits including: improved carbon transfer and homogenization, more intensive heat transfer with improved convection, better residue burn off at front of furnace, reduced soot formation, better cooling zone performance and quicker conditioning when switching atmospheres.
Benefits at a Glance
The nitrogen supply system for the CARBOJET system can also be equipped with a Linde-designed safety solution used to purge flammable atmosphere furnaces to satisfy National Fire Protection Association (NFPA) safety requirements for furnaces (NFPA 86).
Linde offers decades of experience in heat treatment across all common furnace types from continuous to batch type furnaces, including roller hearth, pusher, pit or rotary-retort. Expertise spans all typical protective atmospheres -- from pure nitrogen, pure hydrogen, nitrogen/hydrogen, nitrogen/hydrocarbon type atmospheres to endothermic gas, exothermic gas and monogas atmospheres.
