Product Overview | Ductflame
MARKETS AND APPLICATIONS
Founded in 1976, Fives Group company ITAS is a leader in the European combustion market with specialization in hot air generation. Responding to market demands for a robust high- performance duct burner on the world stage, the Ductflame development was initiated in 2006. Since then, over 2,000 units have been put into service across multiple industries worldwide. Each Ductflame system is custom built to meet the specifications of the customer. Burners feature a combination of cast iron burner sub-sections that are configured into customized combustion air distribution plenums matching the existing process needs. Corner and side fired modules are available to plug-in to your existing ductwork. Systems feature a controlled mixing of air and gas, to optimize emissions and efficiency. Unlike other duct burners, mixing in the Ductflame takes place on the nozzle outlets, thus avoiding the potential for flashback into the burner sections.
The Ductflame was designed for applications requiring the production of large volumes of warm air. Many applications involve producing uniform and clean hot air with a short flame in a duct that is integrated into the process flow of the main machine. Typical applications include dryers, ovens, air heaters, and similar industrial installations in the paint, paper, gypsum, and ceramic drying markets.
OPERATING CONDITIONS
The Ductflame is a custom product built to the customer’s specifications with a wide operating range. See the table below for details.
The Ductflame can run off various fuel types, including natural gas, LPG, biogas, and other gas types upon request.
