PROFIRE* D SERIES BURNERS 4.2 TO 42.0 MMBTU/HR High-efficiency burner technology for the most stringent emissions requirements.

Integration starts with the burner. Only Cleaver-Brooks offers complete boiler systems, from fuel inlet to stack outlet, that are completely designed, engineered, manufactured, integrated, and serviced by one company. And our experience extends to integrating our burners with virtually any boiler, regardless of manufacturer, maintaining peak efficiency and low emissions. ProFire is the global leader in commercial burners, with a full line of high quality, low- and ultra-low-emissions burners specifically engineered to increase your boiler’s efficiency and decrease fuel costs and emissions. With...

Proper burner design minimizes emissions and maximizes efficiency. Computational Fluid Dynamics (CFD) modeling helps design the heat delivery and transfer components into a seamlessly matched Heat Recovery Integrated Controls Water Systems package for optimum heat transfer, highest efficiency, and burner longevity. Absolute compatibility of the burner and furnace is critical to achieving our super-high standard of efficiency. Featuring ultra-low-NOx emissions, from less than 15 ppm and less than 9 ppm NOx on natural gas at 3% O2, each ProFire burner has a special intake box, with a rotary air...

The Cleaver-Brooks ProFire D series burner forced draft design allows for trouble-free operation and superior efficiency on boiler, heater, furnace, kiln, and dryer applications. The uncontrolled configuration offers multifuel versatility. The ProFire D is an excellent choice when firing alternative fuels such as digester, waste oil, and biodiesel. Low-pressure air atomizing system on oil with rotary vane compressor purges air through the large nozzle orifice after each burner cycle to prevent after-drip and fouling. Piston-type positive displacement oil metering system. Cam Trim 14-point adjustment...

The Cleaver-Brooks ProFire LND series burner offers natural gas, propane gas, air atomized #2 and #6 oil, and combination gas and oil fuel options from 3.4 to 42.0 MMBTU per hour, with full modulation operation and standard cam trim for greater efficiency and cost savings. The ProFire LND is an low-NOx bu fflij capable of less than 30 ppm NOx emissions. ProFire LND In addition to all the features listed under the ProFire D, the ProFire LND has these features: Available to <30 ppm NOx. Induced FGR modulating valve and shutoff valve. Cam Trim 14-point adjustment range on FGR feature adjusts the...

Ultra-Low-NOx Configuration The ProFire NTD was designed and developed with a Flue Gas Recirculation system which has been proven to be the benchmark in the industry. Emissions reduction, fuel savings, performance, and reliability make the ProFire NTD an excellent choice. The Cleaver-Brooks ProFire NTD series burner offers natural gas, propane air mix, air atomized #2 oil, and combination gas and oil fuel options from 12.6 to 33.5 MMBTU per hour, with full modulation operation and parallel positioning for greater efficiency and cost savings. The ProFire NTD is an ultra-low-NOx burner capable...

Capacities and RatingsUncontrolled Emissions Configuration (DL, DG, DLG) Burner Sizes Input is based on fuel Btu content and altitude of 2,000 feet or less. If altitude > 2,000 feet and < 8,000 feet, derate capacity 4% per 1,000 feet over 2,000. Consult factory for higher altitudes. Gas input is based on natural gas with 1,000 Btu/cu.ft. and 0.60 gravity. Oil input based on 140,000 Btu/gal. Use model “S” for up to 1.5” w.c. furnace pressure and model “P” for up to 4.0” w.c. furnace pressure. Consult factory for 50Hz. applications. Input is based on fuel Btu content and altitude of 2,000 feet...
