Self-Recuperative Burners for Gaseous Fuels include a recuperator that is integrated into the burner that preheats the incoming combustion air. Burner capacity between 20,000 to 500,000 kCal/hr. The exhaust gases are ‘pulled back’ through the burner by an ejector which is located upstream of the burner. This design arrangement leads to a high air preheated temperature and excellent thermal efficiencies. Type and main material of these recuperators are different based on customers request or burner capacities. They are widely used for heating on either direct or indirect furnace systems in intermittent or modular modes. In indirect heating they can be applied for: Inert gas roller hearth furnaces, Inert gas chamber furnaces, Continuous strip lines, Use in single-ended radiant tubes, P- & double-P radiant tubes, etc.
These types of the burner can operate in flameless or conventional firing modes. In the case of the flameless mode, this burner converts from a conventional low NOx industrial burner to a remarkable ultra-low NOx type.
SRG-M and SRG-S burners are respectively integrated with Stainless Steel and SIC recuperators.
