The Radian Rapid Mix Burner{trademark} for ultra-low NO{sub x} emissions
Radian Corporation together with its licensee, Todd Combustion, has developed, demonstrated, and commercially implemented the Radian-Rapid Mix Burner{trademark} (R-RMB{trademark}) that is capable of producing ultra-low NO{sub x} levels for natural gas firing. NO{sub x} levels under 10 ppm, simultaneously with CO levels of a similar magnitude, have been achieved over the load ranges of several forced-draft industrial boilers. These emission levels have been achieved while maintaining excellent flame quality and boiler performance. The paper gives an overview of the RMB{trademark}`s design features. A review is provided of its performance characteristics established during its development phase in a 4 MBtu/hr firetube test boiler. Data illustrating the burner`s sub-10 ppm NO{sub x} performance with and without air preheat, and for circular and rectangular (for tangential firing) burner configurations are presented. Sub-10 ppm NO{sub x} data for commercial installations in two 5 MBtu/hr firetube boilers, a 26 MBtu/hr watertube boiler, and a 130 MBtu/hr watertube boiler are presented. Data reviewing the burner`s performance for oil firing, and plans for its demonstration in a utility boiler are summarized.
