Combustion Optimisation
Improve burner performance, flame control and fuel efficiency across industrial heating systems.
Improve burner performance, flame stability, fuel-air ratio and process consistency.
The system keeps running. But it is rarely running as it was designed to.
Most industrial burners were selected for a specific process, at a specific time.
Over the years, production needs change. Fuel types change. Operating cycles change. Burners get tuned manually and never reset. Dampers drift. Nozzles wear. Control setpoints get adjusted shift by shift until no one is sure what the original settings were.
The cost shows up in the fuel bill, in uneven heating, in inconsistent output across shifts, in burner maintenance logs and in flue gas temperatures that are higher than they need to be.
Fuel & Energy
High fuel consumption with no clear single cause
Excess air or poor air-fuel ratio control
High flue gas temperature
High emissions
Heat & Quality
Inconsistent furnace or oven temperature
Uneven heat distribution across the load
Flame instability
Consistency & Maintenance
Performance that varies between operators and shifts
Frequent burner maintenance
Poor process repeatability
Encon studies the combustion system as part of the complete thermal process.
The burner is not assessed in isolation. Encon looks at the full picture — furnace geometry, fuel type, heat load, operating cycle, flue gas behaviour, air supply, control system and what the process actually demands at each stage of the firing cycle.
The solution is built around that assessment. It may involve burner replacement, burner resizing, flame pattern correction, air-fuel ratio optimisation, combustion air preheating, control upgrades, recuperative or regenerative burner systems, oxy-fuel conversion or a complete combustion redesign.
Burner selection and replacement
Matching burner type, size and flame pattern to the actual process requirement.
Air-fuel ratio correction
Setting and controlling the ratio across the full firing range to reduce excess air and stack losses.
Combustion air preheating
Recovering flue gas heat to preheat combustion air, reducing fuel demand.
Regenerative systems
REGEN® Burners recover exhaust heat and preheat combustion air to temperatures close to process temperature, reducing energy consumption by up to 50% where recuperators are not present, and up to 35% where recuperators are already installed.
Self-recuperative burners
Burners with a built-in recuperator using flue gas heat to preheat combustion air, reducing fuel consumption and greenhouse gas emissions by up to 30%.
Oxy-fuel conversion
Jupiter–Encon Oxy-Fuel Technology uses pure oxygen for combustion, reducing fuel use by up to 73% in applicable processes.
Controls upgrade
Replacing manual or non-functional combustion controls with temperature, pressure and air-fuel ratio control for consistent, repeatable performance.
Selected around the furnace type, fuel and operating conditions.
Combustion optimisation is delivered through the right combination of burner technology, fuel and air management equipment, and controls.

Combustion optimisation delivers improvements often from the first week of correct operation.
Fuel & Energy
Lower fuel consumption
Less fuel burned for the same delivered heat, once the air-fuel ratio is corrected across the firing range.
Reduced excess air losses
Air is no longer heated and sent up the stack without contributing to combustion.
Lower stack losses and flue gas temperature
Heat that was leaving through the flue is returned to the process as preheated combustion air.
Reduced emissions
More complete combustion lowers CO and NOx without trading away efficiency.
Lower operating cost
Fuel is the largest running cost in most fired processes, so correcting combustion reduces it directly.
Heat & Quality
Improved flame stability
A correctly sized burner and ratio hold a steady flame instead of lifting or pulsing.
Better heat transfer across the load
Flame shape matched to the chamber puts heat into the load rather than the walls.
More consistent furnace and oven temperature
Temperature holds through the cycle instead of drifting between setpoint adjustments.
Consistency & Maintenance
More repeatable performance across shifts
The same result whoever is running the furnace, because the ratio is controlled rather than tuned by hand.
Lower operator dependency
Automatic ratio control replaces manual adjustment as the thing holding the process steady.
