LxE Burner with remote mounted fan	LxE Burner with close coupled fan

Faber LxE Burners are gas fired, forced draft low emission burners for use with either a close coupled or remote mounted fan. These units operate at low excess air levels with turn down ratios up to 10:1. Guaranteed NOx emissions as low as 30 ppm without FGR and as low as 15 ppm with FGR, 50 ppm of CO, and trace amounts of VOC and particulate emissions on natural gas fuel. LxE burners are modular in design and consist of the following sub-components; a fixed geometry register, windbox baffles, gas firing spuds, spark ignited gas pilot, two sight ports, flame scanner mount, three pressure tap ports and a refractory throat assembly.

LxE Low Nox Burner Mounting Positions

Low Emissions, Modular, Flexible, Convenient Installation Options + Quick Delivery = Ultimate Retrofit Burner

The LxE burner can be mounted either vertically up, vertically down or horizontally. Three universal mounting and lifting brackets are located around the burner housing allowing six points to bolt on burner supports and ancillary equipment. The air and gas supply connections can be located in any combination of 45º increments around the axis of the burner to suit site conditions. The entire burner assembly consists of thick steel fabrications designed to provide a long life of trouble free service. Two week deliveries are typical for units supplied with no combustion air fan. Six to eight week deliveries are typical for units supplied with a combustion air fan.
