Webster Introduces New Low NOx Boiler Burner


Winfield KS, January 26, 2017 - Webster Combustion Technology LLC (“Webster”) is pleased to introduce a new boiler burner, the model SC Series, which has been engineered specifically to operate with low emissions without the cost and expense of external Flue Gas Recirculation (FGR) piping or the maintenance issues associated with surface combustion technology.

The new SC Series burner combines the reliable and rugged burner technology Webster is known for with a new, patented staged combustion firing head. The SC burner can achieve 30ppm NOx levels while maintaining a very low O2, which results in excellent efficiency, and can achieve as low as 9ppm NOx levels with an increase in O2.

When combined with Webster’s patented Temp-A-Trim® air density trim system the SC burner will maintain even lower excess air levels as operating conditions change, saving fuel and electricity and lowering maintenance costs.

The SC burner is available for Scotch-Marine, firetube, watertube, flextube, firebox, and other heaters and vessel types. It can fire natural or LP gas or No. 2 oil. It has lower excess air requirements for extremely efficient operation.
