S1-Series
The Series 1 burners are designed for large boilers applications. A forced draft design is able to handle the high furnace pressures, multi-fuels, and is also available as a low NOx <30 ppm with F.G.R. .
Features Include:
  • Dual gas manifold
  • Cam trim for consistent fuel/air ratios
  • High turndown ratios
  • 14 points adjustment range
  • Air or steam atomizing
  • Top or bottom F.G.R. connection
  • Backward-curved aluminum impeller
  • Gas manifold standard on all oil units
  • Hinged swing-away housing for easy service

Notes:
  • Firing rates based on altitudes to 2000ft. above sea level. For firing rates at higher altitudes, consult factory. Gas input based on 1000 Btu/cu. ft. and .60 specific gravity oil input based on 140,000 Btu/gal.
  • Boiler overall efficiency of 80% estimated. Industrial Combustion does not guarantee overall boiler efficiency.
  • Furnace pressure and furnace dimensions and required NOx emissions may allow higher firing rates than shown above, consult factory
  • Shipping weight is only an estimate
  • Motor horsepower based off of standard design backpressure rating. Consult factory for review and comparison to your application.
