S1/LNS1 - Series

S1 series burners are suitable for scotch marine and watertube boiler applications. The standard S1 series offers natural gas, propane gas, air atomized #2-6 oil and combination gas/oil fuel options at capactities from 46,200,000 to 63,000,000 Btu/hour. The low NOx S1 series offers natural gas, propane gas, air atomized #2 and #6 oil, and combination gas/oil fuel options at capacities from 42,000,000 to 58,800,000 Btu/hour. A true forced draft design provides the ability to deliver rated capactities against furnace pressures up to 8" W.C.

Features Include:

Gas, light and heavy oil fuels
Cam trim with 14-point adjustment range for consistent air/fuel ratios
Parallel positioning available for optimal control throughout the firing range
Low NOx with FGR capabilties
Top or bottom FGR connection options
Gas manifold on oil burners standard for easy upgrade to combination units
Hinged combustion head for easy access and maintenance
Backward-curved impeller provides adequate combustion air for various furnace pressures
Air atomizing with steam atomization optional
