1. Ranger Combustion System
Low emissions or high efficiency—
Why should you have to choose?

3. The Ranger Combustion System produces an exceptionally stable flame at all firing rates.
Fuel Variety
Capable of firing natural gas, light oil, heavy oil, digester gas, ethanol, and more, the API offers a wide range of fuel burning capability.
Advanced Design
Our engineers specifically designed this burner to eliminate field errors, reduce space requirements, and facilitate maintenance when needed.
Two models are available: Ranger-RF allows for the fan to be placed remotely; Ranger-AF is designed for smaller applications and ease of maintenance.
High Efficiency
The API burner incorporates a VFD for control of FD fan speed, resulting in significant electrical reductions, regardless of the type of fuel burned.

4. Swing open housing allows for easy maintenance of the burner.
Removable fan housing.
Positioning knob with limit switch extends oil nozzle life by withdrawing the oil atomizer without opening the burner.
Standard stainless steel gas manifold and front head ensures long lasting life and ability to burn corrosive fuels.
External flame scanners (UV or IR).
Direct drive parallel positioning servos.
Servo positioned flame shaping device gives the API the ability to dynamically match the flame pattern to furnace geometry and air pattern across the turndown range.
Recessed front head eliminates the need for burner refractory.
Preferred’s Y-jet air atomized nozzle provides fine oil droplets with reduced atomizing air.

5. The Need Stricter NOx Emissions Standards
Lawmakers Pushing for CO2 Reduction
(example: Local Law 87 in NYC)
Reliable Emissions Compliance with High Turndown, High Efficiency, and Immediate Backup Fuel Option
Reduced Maintenance, Parts Replacement, and Service Requirements

6. How Does the Ranger Combustion System Meet this Need?
Sub 9 ppmc NOx Performance on Natural Gas
Low Excess Air- Less than 3-4% O2 from % Firing Rate
High Turndown – 10:1 on Natural Gas; 8:1 on #2-#6 Oil
Oil Backup Fuel Available in Less than 5 minutes.
No Filters or Mesh Firing Head required.

7. How is this Technology Different?
Ultra Low NOx Emissions with High Combustion Efficiency
Uses Nominally 25% FGR to Achieve <9ppm NOx
Fuel and Air are not Premixed
Typically Safer to Light-off Compared to Premix Burners
Generally, Significantly Higher Turndown than Alternatives

9. Burnermate Universal Boiler Controller
Combustion Control, Flame Safeguard, Draft, and Feedwater Control
How does this complete the Ranger Combustion System?
Precise Servo Control (0.10 degree deadband)
Position Pacing
Low FGR Temperature Hold
Redundant Flame Scanning for Increased Reliability
Draft Control uses Feedforward from Combustion Curve
