XL/ LNXL Vertical - Series

Suitable for large firetube and watertube applications; the XL series features a unique and precise air metering system which permits accurate air-to-fuel settings for maximum combustion efficiency. The XL series offers natural gas, propane gas, air atomized #2 oil and combination gas/oil fuel options at capacities from 37,800,000 to 63,000,000 Btu/hour. Through the use of advanced technology, the XL series offers high turndown up to 10:1 on natural gas and up to 8:1 on light oil.

Features Include:

3600 RPM combustion air fan (Motor HP based on NOx and capacity requirement)
Parallel positioning is required for optimal control throughout the firing range
Low NOx with FGR capabilities
Gas manifold on oil burners standard for easy upgrade to combination units
Hinged rear door and burner access panels for easy access and maintenance
Air atomizing with steam atomization optional
Backward-curved impeller provides adequate combustion air for various furnace pressures
High turndown ratios
