Oxy-Fuel & Future Combustion
Advanced combustion pathways for higher efficiency and lower-emission industrial heat.
Combustion technologies for higher flame efficiency, lower emissions and cleaner heat pathways.
The combustion system is working against itself.
In conventional air-fuel combustion, roughly 79% of the combustion air is nitrogen. Nitrogen does not contribute to combustion. It absorbs heat, dilutes the flame and increases the volume of flue gases leaving the furnace.
For high-temperature applications — aluminium melting, glass, steel reheating, forging — more fuel is needed to overcome the thermal burden of nitrogen in the flame. More flue gas exits at high temperature. Heat transfer suffers. Emissions rise.
Fuel & Heat Transfer
High fuel consumption in high-temperature processes
High flue gas volume and stack losses
Lower flame intensity than the process requires
Long heat-up cycles
Emissions & Transition
Higher NOx formation
Pressure to reduce emissions without rebuilding the furnace
Need to prepare for cleaner fuel pathways — hydrogen, low-carbon — without disrupting current operations
Remove the nitrogen, and the flame does more of the work.
Encon brings oxy-fuel combustion into industrial heating applications where higher flame efficiency and better heat transfer can improve process performance.
Jupiter–Encon Oxy-Fuel Technology uses pure oxygen for the combustion of fossil fuels. By removing nitrogen from the combustion process, the flame temperature rises significantly — oxy-fuel combustion can reach up to 3200°C — and heat transfer to the load improves. Flue gas volume falls sharply, reducing stack losses.
The system operates at or near stoichiometric conditions and can be retrofitted to existing furnace designs and refractories in many cases — making it a practical route to improved combustion without a full furnace rebuild. Encon also develops hydrogen combustion systems for industries preparing for the transition to cleaner fuel pathways.
Jupiter–Encon Oxy-Fuel Technology
Patented oxy-fuel process using pure oxygen. Reduces natural gas consumption by up to 73% and oil fuel consumption by up to 68% in aluminium melting applications.
Oxy-fuel retrofit
Retrofitting oxy-fuel burners to existing furnace infrastructure, using the same furnace design and refractories where applicable.
Oxygen enrichment
Partial oxygen enrichment of combustion air as a step towards full oxy-fuel, used to improve flame temperature and reduce cycle time.
Hydrogen combustion systems
Burner and combustion system design for hydrogen fuel, for industries preparing for the low-carbon transition. Hydrogen combustion produces only water vapour as a byproduct, with zero carbon emissions.
Oxygen/fuel ratio control
Controls for maintaining the correct oxygen-to-fuel ratio, ensuring consistent combustion performance and emissions compliance.
Engineered around furnace type, temperature and emissions requirement.
From single-burner conversions to complete system installations.

Automation & Controls
Less fuel in, more heat delivered, less lost through the flue.
Oxy-fuel combustion changes the energy economics of the process.
Fuel & Heat Transfer
Reduced fuel consumption
Removing nitrogen from combustion removes the fuel spent heating it.
Higher flame temperature and improved heat transfer
Oxy-fuel combustion can reach up to 3200°C, transferring more heat to the load.
Lower flue gas volume
Without nitrogen, far less gas leaves the furnace carrying heat with it.
Reduced stack losses
A smaller exhaust volume means less heat lost through the stack.
Faster heat-up cycles
A more intense flame brings the load to temperature sooner.
Emissions & Transition
Lower NOx emissions
Less nitrogen in the flame means less thermal NOx formed.
Reduced CO₂ emissions
Lower fuel input translates directly into lower carbon output.
Cleaner high-temperature combustion
Higher efficiency at the temperatures where conventional air-fuel struggles most.
Retrofit path available
Without full furnace redesign in many cases.
Future fuel readiness
Hydrogen-compatible burner systems.
Measured on real plants.
