The CARBOJET technology can be applied to most types of heat treatment furnaces including continuous, pit and rotary retort 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.

"For rotary retort furnaces, CARBOJET gas-injection can achieve up to 20 percent higher output when processing bulk materials due to deeper gas penetration," Malas said. "For pit furnaces, gains up to 20 percent can be achieved through more uniform heating and carburizing.  And for continuous furnaces, CARBOJET technology can boost productivity up to 10 percent after better burn off of oily residues at the front of the furnace."
