Large, Forced Draft Burner

  • 37.8 to 92.4 MMBTU input range
  • 900 to 2,200 HP
  • Gas, oil, combination

The ProFire-XL series burners feature a unique and precise air-metering system which permits accurate air-to-fuel settings for maximum combustion efficiency.

Suitable for large firetube and watertube applications, the XL series is offered in two standard configurations- vertical and horizontal. Vertical configurations support capacities ranging from 37.8 to 63.0 MMBTU, and horizontal configurations support capacities from 67.2 to 92.4 MMBTU. The standard, low-NOx and NT vertical and horizontal configurations are capable of burning natural gas, propane gas, air atomized No. 2 oil, as well as combination gas/No. 2 oil.  Steam atomization is optional for both the horizontal and vertical configurations of the ultra-low-NOx NT burners.

Gas manifold on oil burners comes standard for easy upgrade to combination units. Easy access for maintenance is granted through hinged rear doors and burner access panels. A backward-curved impeller provides adequate combustion air for various furnace pressures.

Fan options include 1,800 rpm combustion fans from 1,600 to 2,200 boiler HP or 3,600 rpm combustion fans from 900 to 1,500 boiler HP (motor HP based on NOx and capacity requirement).
