Answer To The Continued Need For Energy Conservation & Conversion
 
 
 
 
Application of Oxy Fuel
 
Oxy Fuel Technology, 250,000 lbs Jupiter Oxy-Fuel Aluminum Melting Furnace Our mission is to promote Oxy Fuel System to businesses that are energy intensive because Oxy-Fuel Technology is able to achieve significant reduction in fossil fuel usage and production of green house gases.

The patented oxy-fuel combustion technology creates more efficient heat transfer for industrial furnaces.

The improved efficiency is due to :-
 

1. Elimination of airborne nitrogen.
2. Increase in radiant heat transfer.
3. Longer gas residence time.

CASE STUDY
 
In the aluminium recycling furnaces where the patented oxy fuel technology is being used the following results were achieved.
 
Decrease in Fuel consumption
 

1. Natural gas fuel reduction up to 73%
2. Oil fuel usage reduction up to 68%

After oxy-fuel technology implementation 560 Kcal/Kg was the average energy requirement for aluminium, which improved to 416 -500 Kcal/Kg with continuous runs eliminating holding time This compares to the prior experience of about 2,009 Kcal/Kg for air fuel combustion.
 
Reduction in Green House Gases
 

For Natural Gas:

  • NOx below 9e-9 Kg/Kcal.
  • 69% reduction in CO.
  • 69% reduction in SOx.
  • 31% reduction in VOC's.
 

For Oil: NOx, SOx and CO well below AP-42

 
OBSERVATIONS MADE IN THE FURNACE
 
  • Flame temperatures exceeded 2,480°C, and reached as high as 2,925°C. This did not affect the refractory of  the furnace.
  • Molten Metal Process temperature is about 760°C.
  • Wall temperature is about 980°C.
  • Stack temperature is about 540°C.
