FlueFire Duct Burners

The Eclipse FlueFire is an in-duct burner which can be located directly in exhaust gas streams and is also suitable for fresh air operation or incineration applications. FlueFire burners consist of a rolled steel channel framework internally insulated and covered with a heat resistant sheet which is attached on the mounting frame and provided with expansion
allowance.

Burner modules are manufactured from high temperature alloy steel, precision cut by laser to ensure uniformity. This, together with the self-cooling design, enables the burner to function with inlet temperatures up to
700°C (1300°F) and outlet temperatures up to 1200°C (2200°F).Each burner module comprises a 6" stabilization plate perforated to create a local swirl in the turbine gas. Rows can be fired individually, or provided with vertical flame propagation plates linking each manifold row.

A turndown over 10:1 is generally obtainable across the full burner matrix without the need to isolate burner rows. This enables the burner to meet changing heat demands while maintaining uniform distribution across the duct area. The design of the FlueFire burner ensures intimate mixing of the turbine exhaust gases with the fuel which creates exceptional flame stability at 100Pa (0.4" w.c.) pressure drop across the burner even on low calorific gases, which in turn ensures clean combustion with low NOx emissions. This is achieved by swirling the turbine exhaust gases intothe gas jets.
