Cleave- Brooks ProFire Burners Includes:
XL Series
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).
Features:
- Various parallel positioning options are available and required
- Up to 10:1 turndown on natural gas and up to 8:1 turndown on oil (for standard and low-NOx models only)
- Up to 6:1 turndown on oil (NT models only)
- Up to 6:1 turndown on natural gas for NTXL units
- Air-atomizing units with steam atomization optional
- Parallel positioning is standard for optimal control throughout the firing range
S1 Series
The standard S1 series offers natural gas, propane gas, air-atomized #2 or #6 oil and combination gas/oil fuel options from 46.2 to 63.0 MMBTU. The LNS1 series offers natural gas, propane gas, air-atomized #2 oil and combination gas/oil fuel options from 42.0 to 63.0 MMBTU to <30 ppm NOx. The NTS1 series offers natural gas, propane/air mix, air-atomized #2 oil and combination gas/oil fuel options from 33.0 to 63.0 MMBTU to <9 PPM NOxGas 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.
The FGR control valve insures proper metering of FGR for maximum NOx reduction; and the FGR shutoff valve is standard, which prevents combustible gases from returning to the combustion zone.
Features:
- C-B NT technology adaptable to all types of combustion chamber configurations
- Top or bottom FGR connection option (LNS1 models only)
- Air-atomizing, low-pressure oil nozzle with steam atomization optional
- Parallel positioning is standard for optimal control throughout the firing range (NT models only)
- Cam trim with 14-point adjustment range for consistent air/fuel ratios (S1/LNS1 models only)
E Series
Low pressure drop firing head design and low blower motor horsepower requirement for increase efficiencies. Advanced technology allows the E series to offer low NOx emissions options, up to 10:1 turndown on natural gas, up to 8:1 turndown on light oil and up to 8:1 turndown on low NOx natural gas.
Features:
- Low motor horsepower for increased energy efficiency
- Induced FGR (Flue Gas Recirculation)
- FGR modulating valve
- Forced draft for clean and efficient combustion
- No. 2 oil capability for backup fuel
- UL/cUL listed
D Series
The true forced draft design of the burners allows for trouble-free operation and superior efficiency across a wide range of applications.
A backward-curved impeller ensures adequate combustion air for exceptional performance at various furnace pressures and high-altitude applications. The cam trim with 14-point adjustment range allows for consistent air-to-fuel ratios. The standard gas manifold on oil burners means an easy upgrade to combination units.
Features:
- Full modulation
- Low-pressure air atomizing system on oil with rotary vane compressor
- Parallel positioning is standard for optimal control throughout the firing range (NTD Model only)
- Piston-type, positive-displacement oil metering system
- Hinged combustion head for easy access and maintenance
- UL/cUL listed (Standard D and LND Models only)
SBR – 30
The ProFire SBR-30 series is designed for a variety of boiler types such as firetubes, and watertubes. Capable of less than 30 ppm NOx emissions without FGR, the SBR-30 series features a unique firing head design to achieve controlled combustion leading to low emissions with 3% O2. Advanced technology allows the SBR-30 series to offer low-NOx, low CO emissions and up to 10:1 turndown on natural gas.
Features:
- Low-NOx Emissions as low as 30 ppm achieved without FGR
- Maximum Efficiency provided by standardized parallel positioning
- Uniform Flame for equal heat transfer allowed by premix fuel
- Easy Access air housing for internal components
- Silent operation with an advanced combustion air fan wheel using less horsepower and less noise
- Lower maintenance cost with no FGR or air filters needed
- Low-NOx/CO achieved without a fragile surface combustion burner head, making it safer and more reliable, and requires less maintenance
- Integrated Controls with remote IoT monitoring capabilities
SBR – 5
The ProFire SBR-5 series is designed for a variety of boiler types such as firetubes, and watertubes. Capable of less than 5 ppm NOx emissions with FGR, the ProFire SBR-5 series features a unique firing head design to achieve controlled combustion leading to ultra-low emissions with 3% O2. Advanced technology allows the SBR series to offer ultra-low-NOx, low CO emissions and up to 6:1 turndown on natural gas.
Features:
- Ultra-Low-NOx Emissions as low as 5 ppm achieved with FGR
- 3~4% O2 across a wide load range
- Maximum Efficiency provided by standardized parallel positioning
- Uniform Flame for equal heat transfer allowed by premix fuel
- Easy Access air housing for internal components
