RESULTS OF CFD ANALYSIS

Jupiter- Encon Oxy-Fuel Technology

1. is a patented process for the combustion of fossil fuels with pure oxygen

2. uses an undiluted high flame temperature, but keeps the same process temperatures

3. combusts at or near stoichiometric

4. retrofitted using the same furnace design and refractories

Conventional Combustion v/sOxy-Fuel

Traditional Combustion

– Air fuel fired 21% oxygen, 79% nitrogen

– 3 to 5% excess air

Relatively Low Flame Temperature

Readily Available Nitrogen to Create NOX. Nitrogen Increases the combustion volumes

78% Potent heat escapes through Stack.

Higher Flame temperature

No change in furnace design and materials

Possibility of variable processes

No change in versatility of the usage

Does not affect Inclusions/impurities in the re-melted aluminum

Results with Aluminum Melting

Improved Energy Efficiency

• 417 – 500 Kcal / Kg for continuous runs

• Elimination of airborne nitrogen

• More radiant heat transfer

• Longer gas residence time

Lower Fuel Costs

• Natural gas fuel reduction up to 73%

• Oil fuel usage reduction up to 68%

Improved Production

• Better heat transfer

Reduction in Pollutants

RAYCON SYSTEMS

• Used to heat fresh patch up lining in Induction Furnace with the help of High Velocity Burners

• Reduced the “down time” of the furnace by 30 minutes and retrofitted 650 units of heating load to a cheaper source of energy for a 7 ton Induction furnace

• Saving of Rs.39,000/month

• Payback period of 9 months

BURNERS

• Oil Burners

• Gas Burners

• Dual Firing Burning Systems

• High Velocity Burners (OIL/GAS)

R&D ACTIVITIES

• Started in the year 1997

• Project sponsored by Gas Authority of India Limited (GAIL) and Ministry of Science & Technology in partnership with Indian Institute of Petroleum, Dehradun

• Developed gaseous film burner with savings of up to 16% compared to conventional burners

• Innovated Gas Heating Elements which can retrofit any heating elements (electric energized) application up to 550°C temperature
